finger command
Hello all,

Here is what I am trying to do. If a user exist, then send an echo "EXIST" or else "DOES NOT EXIST". (under HP-UX)

Kind of:

Code:
#!/usr/bin/sh
USER=mylogin

finger $USER

if $? = 0
then
     echo "EXIST""
else
     echo "DOES NOT EXIST"
fi


Does not work at all. Any idea?

I have no access to HP-UX and finger is not present in my system.
But I would try "who" piped to "grep" for this purpose.

It should be
Code:
if [ $? -eq 0 ];

Checked on HP-UX system

......................................
#!/usr/bin/sh
USER=mylogin

finger $USER > /dev/null ### Will not display the output of finger command

if [ $? -eq 0 ]
then
echo "EXIST""
else
echo "DOES NOT EXIST"
fi

Finger is disabled on all our servers, just like talk, and rwall are.

You would be better of getting the info from the passwd file.

Try:

cat /etc/passwd | grep username 1>/dev/null 2>&1

if [ $? != 0 ]
then
echo user does not exist
else
echo user does exist
fi
