Shell Script Wrapper — Make a script auto-respawn on exit
This shell script wrapper provides a way for you to run a script and ensure that if it crashes or is killed that it immediately restarts.
#!/bin/sh -eu if test $# -eq 0; then echo Please give a command to start >&2 exit 75 fi # execute the monitored command ${1+"$@"} & # get the PID of monitored command pid=$! # make sure when this script finishes, it will kill the started command trap 'kill -9 $pid' EXIT # wait for the monitored command to finish wait $pid trap '' EXIT # recursively restart everything again exec $0 ${1+"$@"}
