Shell Programming and Scripting

hi,

im looking to write a script to end user sessions which are on a paticular program and have been for over an hour so I can free up the system a bit.
I understand that the "who" command lists the current users logged into the system, however it does not let me see what program they are on and how long they have been on it.

If i do a

Code:

ps -ef | grep <username>

then this does provide me with the information I need, question is how do I get it to grep not just one username but every user that is logged into the system currently.

Any help would be massively appreciated

from the who command get the user logged in and save in file and from ps -ef get the processes running for more than hours and use grep -f saved_file for the processes of user currently logged in.

Code:

ps -eo user,cmd,start_time

will output a list like

Code:

JohnF     cat         15:00

You could grep for your progname and have what you requested for.

My ps doesnt like those formats so Ive decided to go along with this which gives me what I require thing is now I don't know how I can kill the user off using the PID without any intervention.

Code:

ps -aef | grep Aug | grep me1010

The PID for the user is in the third column along

---------- Post updated at 09:00 AM ---------- Previous update was at 08:59 AM ----------

This is the output of the command Ive just mentioned, PID is in the third column

Code:

rigbyt  4766  4607   0   Aug 08 pts/124     0:05 /apps/progress//bin/_progres -p me1010rf.p -pf /apps/live/awards/data/awards.pf

As root you can issue kill PID which will send the default TERM (#15) to that process. If that doesn't work, issue kill -9 PID which cannot be blocked by the receiving process. It may be neccessary to inform users beforehand, e.g. using write user.

Does your ps not allow for any formatting/column selection?

this is the format of the ps command I currently have,

Yes thats a good idea Ill incorportae that in the script somewhere

Did you try the user,stime,comm format selectors? Or fname?
