For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
shell script

Hi Graham,

Would u know why the following doesn't work  - the shellscript  takes the username as a parameter
and then i want to find out if has the following process running (prog).
script looks like so
checkuser () {
PID=`prog`
   x=`ps -fu $1 | grep -v "grep" | awk '{print $2}' grep $PID`
   if test -n "$x"
   then
       echo $1  User $PID is running;
       exit 0;
   else
       echo $1 User $PID is not running;
       exit 1;
   fi
}

case $1
       ABC )
       CheckUser "$1";
       break;;

}

I invoke the script by calling it and passing in the ABC (username)

Any ideas whats up in the above script

"Doesn't work" is always a hard one to analyse - can you tell me ehat happens when you try to run it?  Some form of syntax error?  Wrong results? No results when there should be something reported?

Yeah the incorrect result was popping up .. I should have printed out the the first argument instead of the second .. Sorted .. Thanks

Another question you may know off hand -
I am trying to loop through a list of USERNAMES and find out if they are running  a process at all .

I am initialisng the USERLIST like so
USERLIST=`user1 user2 user3`
my loop looks like so

for USER in $USERLIST
do
echo $USER
done

when i run it i get the following  no such user

any ideas ,
nano

I can't imagin why you'll get a "no such user" message from an echo statement ... I think there has to be more to it than that, and that you've only shown me some of the code.
