Re: convert a given dir name to its absolute path

Take a look at File::Spec, the rel2abs method:

$abs_path = File::Spec->rel2abs( "../../etc" ) ;

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -- Brian W. Kernighan

the $abs_path is empty, can you check - $abs_path = File::Spec->rel2abs( "../../"); print $abs_path,"\n"; I got this empty (??) Could you please advice ? Thanks azaria	[reply]

There are bugs in File::Spec that have to do with relative and absolute paths. Some are recently fixed, some fixes are still in developer releases. This may be related. You might want to see if upgrading `File::Spec` helps. See the change log for details. -xdg Code written by xdg and posted on PerlMonks is public domain.

Executed in /usr/local/bin: `$abs_path = File::Spec->rel2abs( "../../"); print "$abs_path\n __OUTPUT__ /usr/local/bin/../..` [download] So it works correctly on my platform (Linux with perl 5.8.4).
