UNIX for Dummies Questions & Answers

Hello,

A file called test2 contains passwd entries from various servers.

- On solaris9 host :

Code:

> cat test1 | cut -d ":" -f3 | wc -l
   18229

- The same file copied with scp to a redhat host (same cksum) :

Code:

$ cat test1 | cut -d ":" -f3 | wc -l
39411

- A perl script running on the redhat host and connecting with ssh to the solaris9 host :

Code:

#!/usr/bin/perl
use strict;
use Net::SSH::Perl;
use Math::BigInt::GMP;
my $ssh = Net::SSH::Perl->new("the_solaris9_host");
$ssh->login("root","");
my $cmd = "cat /tmp/test1 | cut -d \":\" -f3 | wc -l";
my($output, $error, $exit) = $ssh->cmd($cmd);
print "$output\n";

Code:

$ ./test.pl
   39411

Can somebody explain why this BIG difference in the "cut" output on solaris9 and redhat?

Why is the perl script, supposed to send the command as is on the solaris host, gives a different output then the same command direcly from ssh on terminal?

I definitively missed something and need some expert help please.

Thanks a lot.

I don't have a direct answer. Check the Sun host for the paths for cut. You can try:

type -a cut

or

which cut

It could be that somehow the Perl-ssh uses a different path than the interactive login does.
