Is there a version of the who command for Xenix that will give you your
effective user id when presented with who am i?
Say I'm logged in as myself and do an su to become root. Well, who am i
returns your line in the /etc/utmp file. What I want is more along the lines
of who I am now. Is there a version of who that does this?
Thanks,
// JCA

What I want is something similiar to the BSD/SunOS whoami. For example, in a .cshrc file, I want to be able to do this: if (`whoami` == "root") then set prompt = "#" else set prompt = "%" endif Something like that. Somebody gave me a code fragment in e-mail that does return what I want, but shell scripts bomb.

Doesn't the .cshrc apply to the C-Shell being started up and affects the environment of the started C-Shell? I know this is the case for BSD/SunOS.

If you do an su to root and do a logname it will return the login name of the account you logged in as not root. What I want is something that will tell me the login name of the effective user id. I haven't tried the code fragment with sed yet, but I did try your suggestion out and it doesn't work. I want the equivalent of whoami on BSD/SunOS for SCO Xenix that will work on both the Bourne and C Shells. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | What to buy? ** ARPANET : crash!pnet01!jca@nosc.mil | EISA or MCA? ** INTERNET: jca@pnet01.cts.com | When will the bus wars end? ** UUCP : {nosc ucsd hplabs!hp-sdd}!crash!pnet01!jca **--------------------------------------------------------------------------* */

Unfortunatly this is not true. I noticed in passing that I had whoami in /usr/local/bin on my system, and for unknown reason I assumed that it was part of the GNU bin tools distribution. In fact my copy is from the BSD free sources, and was distributed as part of the MGR distribution for xenix. Since the source is so small I've include the shar file below. Enjoy #! /bin/sh # This is a shell archive. Remove anything before this line, then unpack # it by saving it into a file and typing "sh file". To overwrite existing # files, type "sh file -c". You can also feed this as standard input via # unshar, or by typing "sh <file", e.g..
