zombie-killer

Kill processes that (exceed max run time) AND (match command INCLUDING arguments)

• Edit kill-zombies.sh to change timeout and regex.
• Run in a screen or tmux like: 'watch -n 1020 kill_zombies.sh'
• Test by uncommenting the input from test-data.txt.
• Results are logged to file.
• Getting awk: warning: escape sequence `/' treated as plain `/'
• Originally a one-liner:

watch -n 1400 kill $(ps ao etime,pid,args | awk ' /[r]uby .\/grade4/ { gsub(/[:-]/,""); pid=($1 >= 700 ? $2 : ""); if (pid != "") {print pid; d=strftime("[%Y-%m-%d %H:%M:%S]",systime()); print d, pid >> "killing_zombie_process_list.log"; }} ')

Alternatives that might work for you

• killall --older-than only offers match vs command, not argruments. That might be fine for your scenario.
• If you want to make a special user, group, or launch script with a custom name, killall could probably identify your process that way but it is more configuration to maintain.
• pkill doesn't have the --older-than option so requires parsing the ps output as well.
