Regading 'perlipc'
Hi all, I would like to know if there is any possibilty to handle a situation where in while executing a perl script if i press a Control-C (or terminate the execution explicitly) then my code should be in a position to handle it and display a predefined message(or specifically execute predefined code for cleanup) and then actually exit the code execution. Thanks in advance for the help. regards Anand - Heres a new way to find what you're looking for - Yahoo! Answers
Set time period for a statement to execute
Please guide me with some code or documentation for the following problem :- I need to set some specific time for a command to execute. For example, If I am opening a very large file and it takes me more than 3 to 4 seconds then my code should be able to quit the program or kill the process of opening the file and display an error message.

They are all |equally general; or rather they are all, considered as |groups, universal. Every object whatever presents at once |the subject-matter for each of them. In every fragment of |substance we have simultaneously illustrated the abstract |truths of relation in Time and Space; the abstract-concrete |truths in conformity with which the fragment manifests its |several modes of force; and the concrete truths resulting |from the joint manifestation of these modes of force, and |which give to the fragment the characters by which it is |known as such or such. Thus these three classes of |Sciences severally formulate different, but co-extensive, |classes of facts. Within each group there are truths of |greater and less generality: there are general abstract |truths, and special abstract truths; general abstract-concrete |truths, and special abstract-concrete truths; general |concrete truths, and special concrete truths. But while |within each class there are groups and sub-groups and subsub-groups |which differ in their degrees of generality, |the classes themselves differ only in their degrees of |abstractness.* ^F0^Let us pass to the sub-divisions of these classes. The |first class is separable into two parts\p=m-\the one containing |universal truths, the other non-universal truths. Dealing | ^F0^* Some propositions laid down by M˙ Littr\l=e'\, in his book\p=m-\Auguste Comte et |la Philosophie Positive (published in 1863), may fitly be dealt with here. In |the candid and courteous reply he makes to my strictures on the Comtean |classification in ``The Genesis of Science,'' he endeavours to clear up some of |the inconsistencies I pointed out; and he does this by drawing a distinction |between objective generality and subjective generality. He says\p=m-\``qu'il |existe deux ordres de g\l=e'\n\l=e'\ralit\l=e'\, l'une objective et dans les choses, l'autre |subjective, abstraite et dans l'esprit.'' This sentence, in which M˙ Littr\l=e'\ |makes subjective generality synonymous with abstractness, led me at first to |conclude that he had in view the same distinction as that which I have above |explained between generality and abstractness. On re-reading the paragraph, |however, I found this was not the case. In a previous sentence he says\p=m-\ |``La biologie a pass\l=e'\ de la consid\l=e'\ration des organes \l=a`\ celles des tissus, ~DNO 357 ~APG 0020089 ~SPG 82 ~TXT ^C0^wholly with relations apart from related things, Abstract |Science considers first, that which is common to all relations |whatever; and, second, that which is common to each order |of relations.

Hello Anand,
q/STRING/
STRING
A single-quoted, literal string.A generalized single-quote operation.
A backslash represents a backslash unless followed by the delimiter or
another backslash, in which case the delimiter or backslash is interpolated.
for example
$foo = q!Hello World!; This is equivalent to $foo='hello world';
_
qq/STRING/
"STRING"
A double-quoted, interpolated string.
for example
$foo = qq!Hello World!; This is equivalent to $foo='hello world';
_
qr/STRING/imosx
This operator quotes (and possibly compiles) its STRING as a regular
expression. STRING is interpolated the same way as PATTERN in "m/PATTERN/"
Options are:
i Do case-insensitive pattern matching.
m Treat string as multiple lines.
o Compile pattern only once.
s Treat string as single line.
x Use extended regular expressions.
For example
$rex = qr/my.STRING/is;
s/$rex/foo/;
This is equivalent too
s/my.STRING/foo/is;
_
qx/STRING/
STRING
A string which is (possibly) interpolated and then executed as a system
command with "/bin/sh" or its equivalent. Shell wildcards, pipes, and
redirections will be honored. The collected standard output of the
command is returned; standard error is unaffected.
qx(ls); This is equivalent to `ls` (backtics)
qw/STRING/
Evaluates to a list of the words extracted out of STRING, using embedded
whitespace as the word delimiters.
@a=qw(foo bar baz); This is equivalent too @a=("foo", "bar", "baz");
_
quotemeta EXPR
Returns the value of EXPR with all non-"word" characters backslashed.
_
A Small Example
PROGRAM
$ cat func.pl
#!/usr/bin/perl
$foo = q!Hello World\n!;
print "single-quote operation\n\t",$foo."\n";
$foo = qq!Hello World\n!;
print "double-quote operation\n\t",$foo;
$foo = "Hello world";
$pattern = qr!Hello!is;
$foo=~s/$pattern/HELL0/;
print "Regex operation\n\t",$foo;
@a=qw(hello perl world);
print "\nTurn a space-delimited string of words into a list\n\t";
foreach(@a){
print "$_\n\t";
}
$foo="Hello*world";
$non_word_char = quotemeta($foo);
print "\nBackslashed non-word characters\n\t",$non_word_char."\n";
print qx/ps/;
OUTPUT
$ perl func.pl
single-quote operation
Hello World\n
double-quote operation
Hello World
Regex operation
HELL0 world
Turn a space-delimited string of words into a list
hello
perl
world
Backslashed non-word characters
Hello\*world

RE: Reading contents of file
Hi
I have already tried the way u have told but when i use '
while($line=)' and the regex in the if loop then the regex pattern is
matched only once in the current line and does'nt get repeated for the same
line with differnt bookname present in the same line.
For Eg.
If the input is Genesis 45. with 1 chron ..
here genesis an 1 chron are the book names which can be identified by the
function .
the output is:
Genesis 45. eith 1 chron..
here the loop does'nt get repeated for 1 chron.
Please help in this regard

Hi Anand,
You know where its going wrong then change it :)
Ok, I haven't gone into the regex etc. but I see these 2 major problems:
1. $line=; should be also there inside the while loop, to make the
program get the next line in the file, and hence eventually come out of the
loop when it reaches EOF.
Or, make the change the while loop as "while ( $line = )" and put the
regex check in "if" conditional.
2. Again, you want to make some changes to the line you've read, and then
print it to the output file, the line "print OUT $line;" should be in the
while loop, not outside.
See this:
while ( $line = {
if ($line=~m/([123]?[\.\s]*[a-z\\=\.]+)/oi)
{
..
... do what u want if regex matches
...
print OUT $line;
}

RE: Reading contents of file
Hi
I have tried the way u explained, Thanks for that But I have few new problems
. The code after the modification is as below:
open IN, "r1.dat";
open OUT, ">r1.txt";
$/=undef;
$line=;
while($line=~m/([123]?[\.\s]*[a-z\\=\.]+)/cig)
{
$book=$1;
print $book,"\n";
$t_book=$book;
$t_book=~s/\.//g;
$t_book=~s/\\l=([a-z]+)\\/$1/ig;
$t_book=~s/<(|\/)(B|I|SC|U)>//ig;
$quote=bibref($t_book);
if($quote)
{
print OUT "$book";
}
else
{
print OUT $book," ";
}
$line=~s/$book//;
}
close(IN);
Input:
Genesis 45. anand 1 chron mca 2 chron
1 chron kumar
output:
Genesis. anand 1 chron mca 2 chron1 chron
kumar
Here the problems are :
1) The new line character '\n' cannot be detected.
2)I am not able to print the unmatched data i.e in the above example '45'
doesn't match the regex in the while loop so this cannot be printed in the
output file.
Plz suggest me in the matter . Is there any way to find the data which is
unmatched with the regex.
Thanks for the help
Regards
Anand

Ok, got it now J , sorry, I misunderstood your problem earlier.
If you are expecting multiple matches in a single line, then i would suggest,
keep the regex match as it is i.e. while
($line=~m/([123]?[\.\s]*[a-z\\=\.]+)/oi),
But inside the loop when you a find a match and do relevant things, modify
$line in such a way, that you get the next ( may be replace the matched
substring with empty string? ) This way the lop will end once all matches on
the line are found.
Well Im not a Perl expert, so this is what I could think of J But Im sure
there must be a better way to do it!

Subject: RE: Reading contents of file
Hi
I have already tried the way u have told but when i use '
while($line=)' and the regex in the if loop then the regex pattern is
matched only once in the current line and does'nt get repeated for the same
line with differnt bookname present in the same line.
For Eg.
If the input is Genesis 45. with 1 chron ..
here genesis an 1 chron are the book names which can be identified by the
function .
the output is:
Genesis 45. eith 1 chron..
here the loop does'nt get repeated for 1 chron.
Please help in this regard

Hi Anand,
Yo! u know where its going wrong then change it :)
Ok, I haven't gone into the regex etc. but I see these 2 major problems:
1. $line=; should be also there inside the while loop, to make the
program get the next line in the file, and hence eventually come out of the
loop when it reaches EOF.
Or, make the change the while loop as "while ( $line = )" and put the
regex check in "if" conditional.
2. Again, you want to make some changes to the line you've read, and then
print it to the output file, the line "print OUT $line;" should be in the
while loop, not outside.
See this:
while ( $line =
{
if ($line=~m/([123]?[\.\s]*[a-z\\=\.]+)/oi)
{
..
... do what u want if regex matches
...
print OUT $line;
}
}

Subject: Reading conte! nts of file
Hi
I am new to PERL. I have a doubt, The following script is used to read the
contents of a file (word by word (or) word preceeded by a number), check for
the existence of the matched pattern which is done by the help of bookref()
sub, if it is found then the matched pattern is prefixed with the tag
. When I run the following script it goes to unending because it is
not pointing to the next string after the complete execution of the loop .
Please correct me
open IN, "r1.dat";
open OUT, ">r1.txt";
$/=undef;
$line=;
while ($line=~m/([123]?[\.\s]*[a-z\\=\.]+)/oi)
{
$book=$1;
print $book,"\n";
$t_book=$book;
$t_book=~s/\.//g;
$t_book=~s/\\l=([a-z]+)\\/$1/ig;
$t_book=~s/<(|\/)(B|I|SC|U)>//ig;
$quote=bibref($t_book);
if($quote)
{
$line=~s/($book)/$1/ig;
}
}
print OUT $line;
close(IN);
Thanks in advance for the help.

regex problem
Hi all, I have the following problem in the following regex replace. $line=~s!\b($name)\b!$1!g; here this regex finds the exact matching of the content in $name and does the needed but in some examples the variable $name may contain backslash characters like 'gene\l=s\' , in this type of cases the replace string does not work so i have removed '\b' on either side and used the following $line=~s!(\Q$name\E)!$1!g; This works fine but the problem is that the replacement is not done on the exact word but also on substrings which is unnecessary. if i use both \b\b and \Q\E then the code fails to replace. please send suggestions in this regard Thanks in advance for the help Regards Anand - Jiyo cricket on Yahoo!

Hi all while learning hash arrays i have got a doubt i.e if the data is in the following manner Name ABC AGE 25 Book perl Name DEF AGE 20 Book linux Name GHI AGE 21 Book PHP . .. (assume that the above data is already present in a file or it is being accepted from user using a program in the above format) can anyone help me on how to store the data with hash key as the 'Name' and the hash strings as the details of 'AGE' and 'Book' Thanks in advance for the help Regards Anand - Jiyo cricket on Yahoo!

Re: hash array
Hi ,
Thanks for the reply. but can u help me out if the data is large and need a
loop to store(also if possible give instructions if the record has variable or
optional number of fields).

Hello,I think you could do it as following:
my %hash = ( 'ABC' => { 'AGE' => 25,
'Book' => 'perl',
},
'DEF' => { 'AGE' => 20,
'Book' => 'linux',
},
);
Then,you could access the final value,for example the 'perl',with this syntax:
print $hash{'ABC'}->{'Book'};
if you want to access all the value of 'ABC',you can do:
print $_," ",$hash{'ABC'}->{$_},"\n" for (keys %{$hash{'ABC'}});
Hope that helps.

hello,I wrote it as below simply,maybe it's not so good,you could modify it.
use strict;
use warnings;
my %hash;
while(<>)

next if /^$/;

{
my $name = $1;
my $age = $1 if ($_ = <>) =~ /AGE\s+(.*)$/;
my $book = $1 if ($_ = <>) =~ /Book\s+(.*)$/;
$hash{$name}->{age} = $age;
$hash{$name}->{book} = $book;

# then print the value
