echo "ls -l >/dev/pts/3" |at 23:59or we could also direct to a file:echo "ls -lah >/foo/bar/ls.txt" |at 07:00echo '0 4 */3 2 /root/scripts/task.sh' | crontabThis will cause the system to execute the contents of "task.sh" with the sh shell (unless otherwise specified in the ENV or a shebang line) as your user, at whichever times and dates my ridiculous pattern applies to. :D Anyway, cron tables are very powerful and once you get to know the ins and outs you'll realize there are few scheduling-related things you can't do with them.
