Shell Programming and Scripting

Hi,
I wanted to know the significance of different return codes when we do echo $?
I know when $? returns 0 the command has worked successfully.
but what does $? = 1, 2, 3 etc. signify.

Thanks in advance for the help !!!

the return code depends on the command. the man pages should help about this...
