Need Help??

jfw2112 has asked for the wisdom of the Perl Monks concerning the following question:

I'm using the module Net::Telnet and running system commands on a remote host? When a system command doesn't work, I don't see any of the shell error messages. Where do these shell error messages go and how do I capture them? John....

just a way : capture STDERR to file and `cat the file` `$stdout = $t->cmd("some_cmd 2> /tmp/error.tmp"); $stderr = $t->cmd("cat /tmp/error.tmp; rm /tmp/error.tmp");` [download] i can't sure it is good answer =( good luck!	[reply] [d/l]
