When the specified process does not exist, run the restart script to pull it up. # features: #1. this monitoring script can be executed repeatedly and is automatically mutex-free to ensure that only one monitoring script process exists #2. mutex not only depends on the monitoring script file name, but also contains its command line parameters. It takes effect only when the whole file is mutually exclusive #3. for monitored processes, you can specify only the process name or include the command line parameter #4. whether it is a monitoring script or a monitored process, it is always only for processes belonging to the current user # command line parameters that need to be specified # parameter 1: name of the monitored process # parameter 2: restart the script of the monitored process if test $ #-ne 2; thenprintf "\ 033 [1; 33 musage: $0 process_cmdline restart_script \ 033 [m \ n "exit 1fi process_cmdline =" $1 "# Name of the process to be monitored, or the complete command line, you can also run some command line restart_script = "$2" # scripts to restart the process.
