Re: How do you grab username/login id in Unix?

$ENV{LOGNAME} should do it in many cases. It has been defined as the username on all systems I have used.

But the getpwxxx method that gaal showed is probably the best. It should work on more than just unix.

$ENV{LOGNAME} is setted at login time, so if someone log in as popeye and the do su his $ENV{LOGNAME} is again popeye. But if popoye do su - his $ENV{LOGNAME} is again popeye.	[reply]
