Hello,


basically I need a perl equivalent in bash that does which and gives
me the binary path. I need this because I run my script in different
systems I want the binary automatically adjusted.



use Env q/@PATH/;

my $file = shift or exit 1;

my @which_files = grep -x, map "$_/$file", @PATH;

Perhaps FindBin is the module you want. It finds the "binary" of the 
Perl script. See `perldoc FindBin` for details.


FindBin is a standard module and is installed when the rest of Perl is. 
For a list of standard pragmatics and modules, see `perldoc perlmodlib`.

A quick search of CPAN for the word "which" turned up
File::Which.
It may meet your needs.
