How can I use an at command in a shell script?

at-job, linux, shell, unix

Solution

I'd say

at now +10 minutes <<< "rm -rf /tmp/tobedeleted"

For multiline, consider a "HERE-doc"

at now +10 minutes <<ENDMARKER
rm -rf /tmp/tobedeleted
echo all done | mail -s 'completion notification' sysadmin@example.com
ENDMARKER

Problem

I am trying to use the Unix `at` command (for setting a job to run at a certain time) in a shell script. The time will be specified by user input using getopts and optarg which seem to be working fine, the problem is `at`. How do I write the `at` command into the script to run at a certain time based on input from the user? Thanks, Ryan
