Hello,
I am writing a script that will find which user is executing the script.
I found 3 different ways to do this:
#!usr/bin/perl
use strict;
use warnings;
my $logname = $ENV{ LOGNAME };
print "\$logname = $logname\n";
my $user = $ENV{ USER };
print "\$user = $user\n";
my $pwuid = getpwuid( $< );
print "\$pwuid = $pwuid\n";
I noticed that for $ENV{ LOGNAME } and $ENV{ USER }, I can changes the variable value using setenv in csh and export in bash.
But getpwuid's value always gives me the correct value. So should I go with getpwuid to get the correct user that is calling the script?
Is there a better way?
Thank you.
