Hello mldvx4,

An alternative solution would be to change the username through the usermod and also after the /home dir if exists?

Sample of code:

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

my $nname = "monk";
my $name = "testuser";

sub rename_account {
    my ( $name , $nname ) = ( @_ );
    my $username = `usermod -l $nname $name`;
    my $dirusername = `usermod -d /home/$nname -m $nname`;
    chomp(my @dir = `ls -la /home`);
    print Dumper \@dir;
}


# rename_account("monk", "testuser");
rename_account("testuser", "monk");


__END__

$ sudo perl sample.pl

$VAR1 = [
          'total 16',
          'drwxr-xr-x  4 root   root     4096 Mar 19 12:57 .',
          'drwxr-xr-x 24 root   root     4096 Mar  7 15:04 ..',
          'drwxr-xr-x  2 monk   testuser 4096 Mar 19 12:51 monk',
        ];

The script will not produce any error if the user exists etc.

Hope this helps, BR.
