Running Processes after logout

Processes running in the background by shell are usually allowed to continue after logout. Non-redirected output is lost, however.

nohup command

• allows for saving this output by appending it to the nohup.out file in the user’s home directory.
• terminals need to shutdown with exit

at time

• specifies a time for a set of commands (read from stdin with an at> prompt; ^D to end) to be run as the user, whether the user is online or not.

atq

• lists pending at jobs for the user (root gets everyone)

atrm at-jobid

• removes specific at jobs by job number if owner or root
