Linux User Activity Management

Submitted by on March 9, 2008 – 2:59 pm One Comment

The following is a detailed look into managing Linux users and the system resources they utilize. Disabling user access; halting, killing, and re-nicing user processes; controlling disk space allocation are all points covered by this article.

Halting, Resuming, and Killing users

Before taking any of the actions below, you may want to notify the user:

write alex pts/67 << EOF

Alex, buddy, I need to kill you.


Stop a user and his processes:
skill -STOP -u alex

Resume a halted user:
skill -CONT -u alex

Kill and log out a user:
skill -KILL -u alex

Kill and log out all users:
skill -KILL -v /dev/pts/*
