Kill all pid files in the folder

Question

I have a folder filled with .pid files. Each of them has a PID for the work frame. How can I kill every PID in this folder from the command line?

Answer 1

According to the docs it says:

ps -e -o pid,command | grep [r]esque-[0-9] | cut -d ' ' -f 1 | xargs -L1 kill -s QUIT 

Note It looks like a name instead of .pid files.

In addition, the QUIT signal will gracefully kill them. If you want to force them to kill, use TERM instead.

Answer 2

 cat folder/*.pid | xargs kill 

should do it?

If you need to specify a signal, for example KILL , then

 cat folder/*.pid | xargs kill -KILL 

If your pidfiles does not have line feeds, this might work better:

 ( cd folder && for pidfile in *.pid; do echo kill -QUIT `cat $pidfile`; done ) 

Answer 3

Run the command:

 kill `cat folder/*.pid` 

If there are no newlines in the PID files, then the following should work:

 for f in folder/*.pid; do kill `cat "$f"`; done 

Answer 4

Run this - with the reverse steps:

 kill -9 `cat /path/*.pid`

How it works

 pgrep ruby | xargs ps | grep [r]esque | awk '{print $1}' | xargs kill -9 

NOTE. pgrep not supported on MAC OS, as soon as it is useful for some

Answer 6

Leading filling will cause errors. Use sed 's/^ *//g' to remove the leading interval / pad:

 ps -e -o pid,command | grep '[r]esque-[0-9]' | sed 's/^ *//g' | cut -d ' ' -f 1 | xargs -L1 kill -s QUIT
