Force logout after 24 hours idle

fuser -k `who -u | awk '$6 == "old" { print "/dev/"$2'}`
Shell timeout variables (TMOUT) can be very liberal about what is classified as 'activity', like having an editor open. This command string will terminate the login shell for an user with more than a day's idle time.

What Others Think

Check your quotes, please. And run fuser as root. sudo fuser -k `who -u | awk '$6 == "old"{print "/dev/"$2}'` Also will only work on a few flavors of Unix that a) have the age in column 6, b) have the age in 'who -u' output, and c) support the fuser command.

Quoting fixed, thank you arcege. As a non-root user, this will only kill your own sessions (I have this stuck in my .profile). A well-intentioned question: is fuser such a rarity? I've had no problems running this in solaris or linux.
