Finding error code

[nitinkgoud]

Hi Guys,
Can you tell me how to find error code generated by a command.
Say i run a command and its generating an error how do i find out its error code ( i know its done using redirection operator.......but not sure how)?

Like this...

#!/bin/ksh

somecommand

STATUS=$?

print "Final status code was ${STATUS}"

# or this way

anothercommand && print "Success!" || print "Failed!"

It's the "[tt]$?[/tt]" that holds the return code from any command, immediately after the command ends.
