Re: Getting error- connect to Bugzilla(Certificate Authorities to trust)
Thanks David, it resolved.
I am new to Bugzilla. I am really do not know where it went wrong in below

Perl file and STDERR
Hi All,
Can you please let me know the following snippset? why it is used for?
select( STDERR );
$| = 1;
select( STDOUT );
$| = 1;
print STDERR \nThis is india\n\n;
print STDERR Usage: This is build;
print STDERR where: base PL label\n;
and second question
second question:- I want to open a file read+write mode and change the
some content in same file without creating another file and copy to it.
MY SCRIPT(Not working as i wish to )
#!/usr/bin/perl
open(FILE,test.txt) or die Could not open the file: $!;
@file=FILE;
foreach (@file)
{
$_=~s/BLR/bangalore/g;
print $_;
}
close(FILE);
Regards,
Jitendra
Re: Perl file and STDERR
Thank you very much Andy, Nathan, Shawn for your kind help.
I am new to the perl. Why auto-flush is needed here (STDERR autoflushes)?
It will free the memory or something else.

Jitendra

You might want to look at the perl in place mode [1], so something like
perl -i.bak -pe ' s/BLR/bangalore/g;' myfile.txt
will modifiy myfile.txt, as in a while loop (via the -p option:
while () {
s/BLR/bangalore/g;
}
) and, as there a param to the -i option, leave you with the original text
in a myfile.txt.bak file
[1]
perldoc perlrun has
-i[extension]
specifies that files processed by the construct are to be
edited in-place. It does this by
renaming the input file, opening the output file by the
original name, and selecting that output file
as the default for print() statements. The extension, if
supplied, is used to modify the name of the
old file to make a backup copy, following these rules:
If no extension is supplied, no backup is made and the current
file is overwritten.
If the extension doesn’t contain a *, then it is appended to
the end of the current filename as a
suffix. If the extension does contain one or more *
characters, then each * is replaced with the
current filename. In Perl terms, you could think of this as:
($backup = $extension) =~ s/\*/$file_name/g;
This allows you to add a prefix to the backup file, instead of
(or in addition to) a suffix:
$ perl -pi'orig_*' -e 's/bar/baz/' fileA# backup to
'orig_fileA'
Or even to place backup copies of the original files into
another directory (provided the directory
already exists):
$ perl -pi'old/*.orig' -e 's/bar/baz/' fileA # backup to
'old/fileA.orig'
These sets of one-liners are equivalent:
$ perl -pi -e 's/bar/baz/' fileA# overwrite
current file
$ perl -pi'*' -e 's/bar/baz/' fileA # overwrite
current file
$ perl -pi'.orig' -e 's/bar/baz/' fileA # backup to
'fileA.orig'
$ perl -pi'*.orig' -e 's/bar/baz/' fileA# backup to
'fileA.orig'
From the shell, saying
$ perl -p -i.orig -e s/foo/bar/; ...
is the same as using the program:
#!/usr/bin/perl -pi.orig
s/foo/bar/;
which is equivalent to
#!/usr/bin/perl
$extension = '.orig';
LINE: while () {
if ($ARGV ne $oldargv) {
if ($extension !~ /\*/) {
$backup = $ARGV . $extension;
}
else {
($backup = $extension) =~ s/\*/$ARGV/g;
}
rename($ARGV, $backup);
open(ARGVOUT, $ARGV);
select(ARGVOUT);
$oldargv = $ARGV;
}
s/foo/bar/;
}
continue {
print; # this prints to original filename
}
select(STDOUT);
except that the -i form doesn’t need to compare $ARGV to
$oldargv to know when the filename has
changed. It does, however, use ARGVOUT for the selected
filehandle. Note that STDOUT is restored as
the default output filehandle after the loop.
As shown above, Perl creates the backup file whether or not
any output is actually changed. So this is
just a fancy way to copy files:
$ perl -p -i'/some/file/path/*' -e 1 file1 file2 file3...
or
$ perl -p -i'.orig' -e 1 file1 file2 file3...
You cannot use -i to create directories or to strip extensions from
files.
Perl does not expand ~ in filenames, which is good, since
some folks use it for their backup files:
$ perl -pi~ -e 's/foo/bar/' file1 file2 file3...
Note that because -i renames or deletes the original file
before creating a new file of the same name,
UNIX-style soft and hard links will not be preserved.
Finally, the -i switch does not impede execution when no files
are given on the command line. In this
case, no backup is made (the original file cannot, of course,
be determined) and processing proceeds
from STDIN to STDOUT as might be expected.

Hi All, I need to truncate last few bytes of file. these files are big in size. One idea is to write needed bytes to another file and delete the original file, but i am dealing with big files :( dont want to use truncate, it just truncating the size, all data is gone any pointers Thanks a b

Do you have strict and warnings? Also see:
http://perl-begin.org/tutorials/bad-elements/
And you should probably use a date+time module:
http://perl-begin.org/topics/date-and-time/
$year += 1900;
$mon += 1;
open FH,echo $year-$mon-$yday $hour:$min /home/me/scriptest/
calls_BH |;
while (FH) {
print;
}
close FH;
What are you trying to do here? Use three-args open (see the bad-elements link
above), and don't resort to shell tricks for what can be done in Perl. You're
appending the echo command's STDOUT to a file and then you're trying to pipe
it out to Perl, but there won't be anything to pipe. This can be done in pure-
Perl using File I/O.
open FH1, snmpget -v1 -c mee 1.2.3.1
1.3.6.1.4.1.1768.100.70.40.2.1.4.2 /home/me/scriptest/calls_BH |
or die;
while (FH1) {
print;
}
close FH1;
Again, same problem. Don't use open to execute shell commands. Use system
instead. In your case, you might wish to use backticks or open -| to trap
the output of snmpget.
The text in the file looks like this:

The easiest solution in your case would be to add the -n flag to echo, which
will supress adding a newline. But you should revamp your script from the
ground's up.
Yeah i`m a total nub :)

Hi All,
How to delete last 10 lines of a file using Perl one liner?
I used the following one liner to delete first 10 lines of a file,
perl -i.bak -ne 'print unless 1..10' test.txt
If it doesn't have to be a one-liner, you can do it efficiently using the
following script:
#!/usr/bin/perl
use strict;
use warnings;
use File::ReadBackwards;
use Getopt::Long;
my $count;
GetOptions(
n=i = \$count,
);
if (!defined($count))
{
die Please specify -n for the line count.;
}
my $filename = shift;
my $bw = File::ReadBackwards-new($filename)
or die Could not backwards-open '$filename' - $!;
foreach my $idx (1 .. $count)
{
$bw-readline();
}
my $wanted_len = $bw-tell();
$bw-close();
open my $truncate_fh, +, $filename
or die Could not truncate-open '$filename' - $!;
truncate($truncate_fh, $wanted_len);
close($truncate_fh);
If you still insist on it being a one-liner, see:
http://mail.perl.org.il/pipermail/perl/2005-August/007316.html
You can do it as a one liner in a much less elegant way by using a cyclical
queue, but I can't be bothered to implement it.

Hi Jenn,
You can fing max and min value as,

my $min = (sort { $a = $b } @ar)[0];

ICMP unreachable from 200.69.22.146 to 200.61.54.55 on
interface outside
I wrote this script:
#!/usr/local/bin/perl
$file = '/var/log/messages'; # Name the file
open(INFO, /var/log/messages); # Open the file
while
$message = INFO / IDS/g {# Read it
into an array
$ message = $
sub sendEmail # simple Email function
my $sendmail = '/usr/lib/sendmail';
open(MAIL, |$sendmail -oi -t);

Close.
You do the login correctly in example 1, but then you use print to
issue the command. all that does is print the string /usr/bin/ls\n
to the remote terminal and return 1 to let you know the command
succeeded. If you want the output of the remote command, you need to
use cmd (in list context)
In example 2, you don't pass a password to login or waitfor one, so
you never login. You do, though, use cmd, which is what you want,
although you need list context:
$t-open(host1);
$t-waitfor('/login:.*$/');
$t-print(root);
my @forecast=$t-cmd(/usr/bin/ls);
my $scalar_forecast = join , @forecast;
# or join'\n', I don't remember if cmd returns newlines or not

Hi Mathew :
This is what your regexp ($line =~ s/^.*\s//g;)means : Remove any

If I understand right what you want to do is preserve the name of
the subfolder, if that is correct then you may need this regexp:
$line =~ s/.*[\s+\t+](\w+)/$1/
this regexp does : Remove any character follow by : one or more spaces
or one or more tabs, follow by one or more words(check the perldoc if
you do not know the meaning of \w) and all this patron replace it with
$1 which is the (\w+) and should be(according to your example) =A

I hope it help =D

I then created a simple script that I hoped would eliminate everything
prior to the last bit of text which follows the big space.
open FILE, H:\My Music\folderlist.txt;
foreach my $line (readline FILE) {
$line =~ s/^.*\s//g;
open FILE2, H:\My Music\artists.txt;
print FILE2 $line . \n;
close FILE2;
}
close FILE;
Not only do I think the regex is very wrong, but it isn't doing
anything. If I had to guess, it is saying to replacy everything up to
the first space with nothing. While this isn't what I want it to do,
having it do that would probably be a good step in the right direction.
However, it won't even do that.
What am I doing wrong here?

I am using Spreadsheet::WriteExcel to populate
certain
columns which is working, but in column A for
example
I am using the method write_col which requires a
reference,
Not just a reference but an ARRAY reference for
all the values that
will go into that column (or a reference to an array
of arrayrefs to
write a rectangular area in one shot). The example
about a fifth of
the way through the Spreadsheet::WriteExcel pod
shows it pretty clearly.
I am printing the absolute path
/home/dbsmith/passwd.dubhpr01.sun when all I need
to
print is sun and in column B all I will need is
dubhpr01 or the hostname.
So stop printing what you don't need, and start
printing what you do
need :) :) :) This code is not writing itself --
you have to take a
smidgeon of responsibility for its output.
For this reason I am trying
to use a regexp to grab $1 and $2 or sun and
dubhpr01
then use write_col method. This is not working
and in
my test code I want to know what data structure to
use.
Are you sure that write_col is the method you want
to use in this
case?
use strict;
use warnings;
use Data::Dumper;
my $string =
qw(/home/dbsmith/passwd.dubhpr01.sun);
my ($host,@OS) = $string =~
m|\.(\w+\d+)\.(\w+)$|i;
my $aref = \$host;
my $aref2 = [EMAIL PROTECTED];
Slow down a bit -- think about what you are writing.
I don't want to
seem bitchy, but you often post code that looks like
you just keep
throwing code into the file willy-nilly trying to
see what sticks.
This code CLEARLY has that feel.
#print $1,\n;
#print $2,\n;
if (ref ($aref) eq SCALAR) {
print yes\n;
}
print newline\n;
if (ref ($aref2) eq ARRAY) {
print YES\n;
}
print ${$aref},\n;
print @{$aref2}[0],\n;
__OUTPUT__
yes
newline
YES
dubhpr01
sun
so my question 1 is what is @{$aref2}[0] and
$aref2 is[ 'sun' ]
@{$aref2} is ( 'sun' )
@{$aref2}[0] is 'sun'
Perhaps the reason you find yourself getting
confusing output is your
confusing variablenames. aref2 says nothing about
the data it
contains, and is dangerously similar to aref. If
you are debugging
something, you are going to see what SHOULD be there
instead of what
IS there.
why isn't write_col writing its data from my code
below:
##-- Write data from ref and format cells A2 and
down
--##
my $string =
qw(/home/dbsmith/passwd.dubhpr01.sun);
my @host = $string =~ m|\.(\w+\d+)$|i;
my $aref = [EMAIL PROTECTED];
print @{$aref},\n;
if (ref ($aref) eq ARRAY) {
print YES\n;
$worksheet-write_col('A2',$aref,$sheet_format);
}
It worked for me. (Outside of the fact I had to
redact the
$sheet_format because you didn't post a complete
runnable program.)
I then tried
$worksheet-write_col('A2',@{$aref},$sheet_format);
and I get error:
[error redacted]
Well, the documentation pretty clearly calls for an
arrayref in the
second argument to write_col, so I have no idea why
you tried passing
in an array.
thank you
derek
I know its an ARRAY reference why u think I wrote eq
ARRAY.
I am not 100% sure write_col is the method I need,
that is why I post emails to this list, but I need to
write data in each respective column so using
write_col seems logical.
Sorry u think that, but I do think about what I write
and how to get to my end goal and yes you do sound
bitchy and rude! My apoligies I am not a Perl know it
all but this list is for posting questions so why do
people like u have to make things more difficult by
being negative?
yes the code I provided with the OUTPUT was only test
code or as u state it willy nilly. I did not want to
post all 186 lines so I took out what is not working
which is know as a snippett.
If you seem to have all the Perl knowledge then get
this code working and send me the output BECAUSE IT IS
NOT WORKING FOR ME!

So moving on, I was able to gat all the files using an scp script and for those w/out an ssh client I used ftp. That was a freak-in pain! Now I need to parse through all 238 files to pull certain fields out delimited by : My question is what does everyone think the most practical way to go about this in terms of a data structure? No necessarily the best but most ideal. To me ideal means most practical in an efficient way. My 1st thought was a hash for each file wherein the key would be the hostname and the values the fields. I know there is a way to create dynamic hash's on the fly but need some guidance on docs? I then thought what about a hash containing a glob of the files. my @diraray = glob(/home/dbsmith/draft_files.*); The keys would be the filenames and the values would be the fields after successive opens. In both situations, my goal is to attain the UID fields that DO NOT match then print out the remaining selected fields. The file sizes range from 700 (18 lines) bytes to 50574k (614 lines). thank you derek -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

Hi Derek, Sorry for not providing an answer to your question (I *think* your question is answered by the manual. If not, wait for zentara :-) ) I may miss something but it may make the person(s) who are responsible for security nervous to hear of plans/thoughts - to transfer hundreds of passwd files unencrypted over the network - to place them in the /tmp directory with predictable file names - of seeing disallowed root login, locked down files, and missing ftp as a problem At least I would get nervous (although not having access to hundreds of boxes...) Dani I can understand you comments, but I am behind several firewalls, I changed it from /tmp to my home dir with permissions of 400. scp is being used as a work-around while a manual login will have to be done for those systems that do not have ssh turned on. I was hoping for socket data transfers to mimic an sftp/ftp get without having to deploy code to the clients and or deploying this module on the clients. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

He took the user account under which the scripts are executing and added a path to the profile to point to the location of the old Perl but when he uses it and does a perl -version he still gets a return of the 5.8 version. He feels this is a guarantee that his scripts will be hitting the wrong version and wants to know why he cannot version query the old Perl. My question is it even possible to successfully work with two versions of Perl..5.005 and 5.8 on the same server...and I don't mean just different modules. I saw that there is a use command to access different module versions but I don't know if that applies to using the whole Perl version. I do plan to insist he rewrite for the new version soon but if I could do anything for him quickly to make his scripts use the old version I will. It's absolutely possible. In fact, it's recommended when upgrading. The likely culprit here is the bang path. He can alias the shell variable, but if the first line of the script is still #!/usr/bin/perl then /usr/bin/perl is the Perl that will be used. What he needs to do is go into the scripts that he's worried about and point them to #!/usr/lpp/oldperl/perl5.005_03 ...or wherever the actual executable for the old Perl is hiding.

Disk device drivers are examples of device drivers that use this value. 0x1 (System) = Loaded by the I/O subsystem during Kernel initialization. The mouse device driver is an example of a device driver that uses this value. 0x2 (Auto load) = Loaded by Service Control Manager. To be loaded or started automatically for all startups, regardless of service type. The parallel port device driver is an example of a device driver with a value of auto load. The Alerter service is one of the services that uses this value. 0x3 (Load on demand) = Loaded by Service Control Manager only when explicitly instructed to do so. Available, regardless of type, but it is not be started until the user starts it (for example, by using the Devices option in Control Panel). 0x4 (Disabled) = Do not load. Windows NT sets device drivers to disabled when Service Control Manager should not load them, such as when the corresponding hardware is not installed. Having this value means that the device drivers are not loaded by Service Control Manager. File system drivers are the one exception to the Start value. They are loaded even if they have a start value of 4. If a device driver is accidentally disabled, reset this value by using the Services option in Control Panel.

Because that's almost never what you want when you're writing to a terminal, the standard I/O library that Perl uses takes care of it for you. When a filehandle is attached to the terminal, as STDOUT is here, it is in line buffered mode by default. A filehandle in line buffered mode has two special properties: It's flushed automatically whenever you print a newline character to it, and it's flushed automatically whenever you read from the terminal. The second property is at work here: STDOUT is flushed automatically when we read from STDIN. __ Do You Yahoo!? Tired of spam? Yahoo!

my $line = abcxxabcxxxabc;
if ($line =~ m{(.*?(?:(?!xxx).))xxx}){
print matched: $1\n;

$cpath = File::Spec-canonpath( $path ) ;
Note that this does *not* collapse x/../y sections
into y. This is by design. If /foo on your system is a
symlink to /bar/baz, then /foo/../quux is actually
/bar/quux, not /quux as a naive ../-removal would give
you. If you want to do this kind of processing, you
probably want Cwd's realpath() function to actually
traverse the filesystem cleaning up paths like this.

Re: Smart assignment
returns true or false (1 or '') and in list context it returns the contents of any capturing parentheses in the pattern. The expression: ( $ptypeline =~ /movable.+(sine|geo|radial|ortho)/i )[ 0 ] is a list slice so the regular expression is in list context but the slice is a single value so the expression is a scalar. The || operator will only work with scalar values, not with lists, so this works because the list has been converted to a scalar with the list slice.

variable is undefined, the ... operator will read
the entire file all at once?
thx...

Join with '': a) a randomly selected entry from @a excluding the digits at positions 0..9 [the part between the 1st and 2nd comma] b) five randomly selected entries from @a [the map part] Note: @a is used in scalar context both times, meaning the number of entries in @a. perldoc -f map perldoc -f join perldoc -f rand My tip for cases where you get a working solution you don't understand fully: a) Try to find out what belongs together (imagine '()'s) b) Try to break the solution apart according to the findings in a) c) examine the parts: print them out, dump them with Data::Dumper, modify them, read the man pages d) put them together again, eventually one by one part, using examination techniques as in c) Hope this helps! Dani I reread the docs and I am still unclear with the code: $a[ 10 + rand( @a - 10 ) I do understand everything but $a[ 10 + rand( @a - 10 ) b/c you say subtract 10 from each element occurrance = @a - 10 then add 10 to the result of rand (@a - 10) To me this is offsets itself which is why I am confused. Will you explain again? I think you missed an explanation step between a and b? Reagardless it work so thank you. Does this slice help demonstrate it? my @a = (0..9,'a'..'z','A'..'Z'); my @b = @[EMAIL PROTECTED]; print @a, \n; print @b, \n; # OUTPUT: #0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ #abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQ # BTW, placing print statements in the right places is a great way to learn how someone's program works. Anyway, I hope this is easier to digest: my @a = (0..9,'a'..'z','A'..'Z'); my @b = @[EMAIL PROTECTED]; my $password = $b[int rand (@b)]; $password .= join '', map $a[int rand (@a)], (1..5); print $password, \n; __HTH__ yes this explains it... thank you. __ Do You Yahoo!?

I will try to use the /e modifier as such:
s/(\$\w+)/$1/e;
An explanation is below:
/e
Righthand side of a s/// is code to eval
/ee
Righthand side of a s/// is a string to eval, then
run as code, and its return value eval'led again.
