su command difference between unix and linux

Hello all
the su with -l option is running normal with linux but when i try to run it on unix AIX 5.2.7 it's not working with -l option
any help
# 2  
It may the su version problem . Please check whether both the linux and unix AIX 5.2.7 using the same version.
# 3  
Have you checked the man page for su? Because it doesn't say anything there about a -l switch.

The -l that Linux supports is something borrowed from BSD, and just doesn't appear in any non-BSD inspired system (like AIX or HP-UX)
# 4  
how to get the su version on aix ?
# 5  
Just use:
Code:
su - username

Should be the same in unix (incl. AIX) and Linux. (Exactly the same effect as "su -l username" in Linux).
# 6  
i already work with su - user name on AIX but i'm adding an alias for su in the .profile so i have to add the -l flag .
can any one tell me why su -l is not working on AIX
note : i already installed sudo from AIX toolbox CD but still the same problem
# 7  
Read the whole thread again. The -l flag is something the Linux variant of su borrowed from BSD, and isn't available on any system that didn't at any time borrow from it too. Those include HP-UX and AIX.

In short:There is no way for a current version of the native su program on AIX to support the -l switch without possibly ripping up a glaring, warranty-voiding security hole.
