Hi Billy,
can't see anything wrong with the code, except that it assumes that the
file is in the current directory. It's not something as daft as you
'cd'ing to that directory before you ran in debug mode is it?

Hi Kaustav,
You can do something such as:
#!/usr/bin/perl -w
use strict;
my $file = "foo.file";
open(FILE, $file) or die "Can't open $file: $!";
my @lines= ;
close FILE;
@lines = grep {!/\.(txt|scc)$/} @lines;
print qq{$_\n} for @lines;
This isn't "deleting" from the array, rather reformin

You're right, your way is better. I tend to write code that is
clear to the way I think and then optimize it later (usually
with a profiler). Should get more in the habit of "use re 'debug'".

Others have given you some good stuff about deleting from the array, but

You have "use strict" turned on, so put "my" in front of $fh in line

Yep, you're right. map is slightly slower when it actually has

Welp, if &subroutine_1 is in Library1.pm,
then within Library2.pm, you could do something like:
sub subroutine_2 {
require "/path/to/Library1.pm";
&subroutine_1;
}

That depends:
First you have to load the file via 'require' or 'use' - perldoc them.
If your other .pm creates its own namespace, you need to addre

Hi all,
I am executing a perl script from a directory other than the one it is
located in. I have a package that the script is using located in the same
directory as the script, but the script cannot find this package because
the package is not in the include directory. I need a way to incl
: but I am having trouble stripping $0 of the perl script name.
The standard File::Basename module has a dirname() function
that will do that for you.
Alternatively, you can say something like this in your perl script:
use lib '/path/to/your/module/file.pm';
-- tdk
I cannot use a fixed library path as the script will be installed in
different directories on different systems.
the idea is it will be executed as:
/home/dbncc/perl/scripts/.pl
and the library will also be located in the same directory.

Thanks for the suggestions however I think I need to clarify

I am using a WinNT system and I'm running a script that calls

that in is in file2.pm.

Does your file1.pm have "use file2" in it?
