What Others Think

As is, this runs until shutdown. Output of pgrep could be banished to /dev/null (current usage loops the pid to terminal) while pgrep wget > /dev/null 2>&1 || sudo shutdown -P now; do sleep 1m; done could be expanded to do something every time the process is not-running (e.g. re-spawn/keep-alive) while pgrep gcalctool > /dev/null 2>&1 || gcalctool ; do sleep 0.1s; done and, just in case one wants to use this for a single catch of a program stopping (e.g. notify when this process finishes this time) a break could be inserted to stop the looping while pgrep wget > /dev/null 2>&1 || { zenity --info --text="wget is finished"; break; }; do sleep 1m; done ^example assumes zenity but one could also use notify-send, mail, whatever...
