It is not your friend. You should be able to do "svn add "admin/upload_data/FINAL leg list svn add "admin/upload_data/FINAL leg list 19_01_2010 to agar (Merged data in one).xls" > however there are some special characters like ( ) +#@ that svn cannot > understand as the full path of the file . Well, *YES*. You're going to have difficulty getting characters that mean things to the subversion somponent numbering scheme or the Subversion URL scheme, such as '@', '/', and '#' into the actual filenames. Even if you can leverage your way past this by stuffing in enough backslashes, you're effectively destabilizing your Subversion repository and scripting to handle it, especially post-commit scripts. > can some one help me in this in perl or in shell . > > -- > Regards > Agnello D'souza Can you first explain why you want, or need, to do this? -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/

Re: Extracting properties from objects.
Hi Sean, In your given example, $l becomes a link object, so you go: $l->url(); to get the URL, for example. After using your code below, look at this page: http://search.cpan.org/~petdance/WWW-Mechanize-1.66/lib/WWW/Mechanize/Link.pm That will show you how to use $l. Hope that helps, Ben On 24 Jan 2011, at 10:17, Sean Murphy wrote: > Hi All. > > I am wondering how do you extract properties from objects. If we use > WWW:Mechanize as an example.

1. I suggest you try using Subversion's SVN::Wc API:
http://search.cpan.org/perldoc?SVN::Wc
It is written in C and has bindings for Perl and other languages, and it more
reliabale than parsing the command line.
2. If that fails you can try this:
[code]
#!/usr/bin/perl
use strict;
use warnings;
open my $svn_st, "svn st|";
my @files_to_add;
while (my $line = <$svn_st>)
{
chomp($line);
if ($line =~ m{\A\?})
{
push @files_to_add, substr($line,8);
}
}
close($svn_st);
system("svn", "add", @files_to_add);
[/code]
Note that I've used the list form of perldoc -f system.

You can see some of the things I have tried

I know I can do this link extraction myself with

Hey Mike
What you have written can be fixed by changing it to
for (my $num = 0; $num <= $#linkder; $num++) {
print STDERR "@{$linkder[$num]}\n";
}
or even
for (my $num = 0; $num <= $#{$links}; $num++) {
print STDERR "@{$links->[$num]}\n";
}
but it is much clear and more Perlish to write
foreach my $link (@$links) {
print STDERR "@{$link}\n";
}
Remember: everywhere you could put a simple variable identifier you can
put a reference. Surrounding it in braces is always valid and helps
resolve ambiguity, so @linkder is the same as @{linkder} is the same as
@{$links}. Likewise, $linkder[$num] (or $links->[$num]) is an array
reference, and can be dereferenced with @{$linkder[$num]}.
HTH,
Rob

I think one of the kde or gnome process monitors would show a pretty picture of windows performance. However, I'd look into snmp, nmap (maybe), perl, metasploit (if you want to hack apart ruby). Ps - msf would definitely be the funniest solution to bring to your boss (depending on your threshold for humor). Though using an nmap plugin or installing an snmp server on every box might be the easiest.

Re: Reading a value from a hash using a variable for the key
Guys You claim : s/.*TTL=//; will erase the line, leaving with an empty (uninitialized) $line variable. I want to ask : If so, how print "TTL = $line\n" does give me the right value ! If it will leave $line containing a null (zero-length or undef) string - how can I print it ?

Extracting properties from objects.
Hi All. I am wondering how do you extract properties from objects. If we use WWW:Mechanize as an example. How would you get the properties of the first link. Lets say: my $l = $mec->find_link (text => 'link'); So I would like to find out the text of the link, URL, attribs, etc. This is just an example. When I review the CPAN doc, they don't show this type of information. Sean

Well, the indentation here is wrong, so it's hard to read. This seems like an
artefact of an indentation preserving mode while pasting without a special
reservation for preserving indentation.
