[xubuntu-users] Detecting login name after su

[Joshua O'Leary]

You could pass the username as a parameter to the script at runtime:
myscript.sh `whoami`

Accessing it with the $1 (or whatever number the parameter is) in the 
script.
'logname' may also be an option but I think it needs to be running in a 
tty/vt to work.
