[p4] Problem running p4 command line from a perl script.

[Biswajit Dash]

Hi All, 
I have a perl script which executes p4 commandline to
find out list of pending changelists.

When I execute the p4 command in commandline, It works
fine. however when the same command gets executed from
the script, I get 
Perforce password (P4PASSWD) invalid or unset.

I am sending the 
script and command/output logs 

xyz at biswajit>>cat test.pl 
#!/usr/bin/perl
my $p4 = 'p4 ';

my $cmd = "$p4 users";
my @output = `$cmd`;
print("CMD:$cmd\nOUTPUT:@output\n\n");

$cmd   = "$p4 -u padmin changes -s pending";
@output = `$cmd`;
print("CMD:$cmd\nOUTPUT:@output\n\n");

##############End of script##############
xyz at biswajit>> p4 counter security

CMD:p4  users
