Hi,

I would like to build a module that will contain full paths to frequently used system commands (e.g., cp), so I could 'use' it in the beginning of my Perl scripts.

Has someone created such a module already (I couldn't find it on either CPAN or in google) ?

My (obviously flawed) attempt is as follows:

The (abbreviated) module:

 
$ cat LinuxCommandsPaths.pm
package LinuxCommandsPaths ;

use strict ;
require Exporter;
my @ISA = qw(Exporter);

my @EXPORT_OK = qw(
                        $cat
                        $cleartool
                        $chkconfig
                ) ;

our $cat = '/bin/cat' ;
our $cleartool = '/usr/atria/bin/cleartool' ;
our $chkconfig = '/sbin/chkconfig' ;

1;

[download]
And the testing script:

 
#!/usr/bin/perl -iw
#

use LinuxCommandsPaths qw(:DEFAULT $cat $cleartool $chkconfig) ;

my $cat=$LinuxCommandsPaths::cat ;

print "\$cat == |$cat|\n";
__END__

The problem, as you can see, is that I couldn't find the correct way to import the '$cat' variable so I could just write:

print "$cat \n" ;

[download]
but I have to have the horrid:

my $cat=$LinuxCommandsPaths::cat ;

[download]
which defeats the whole idea of the module.

Any help would be appreciated.

Ron.
