Already running cmd
c=$(pgrep sleep) && sleep 5 && kill $c
Find and kill multiple instances of a process with one simple command.
Only useful for really flakey connections (but im stuck with one for now). Though if youre in this situation ive found this to be a good way to run autossh and it does a pretty good job of detecting when the session is down and restarting. Combined with the -t and screen commands this pops you back into your working session lickety split w/ as few headaches as possible.
And if autossh is a bit slow at detecting the downed ssh connection, just run this in another tab/terminal window to notify autossh that it should drop it and start over. Basically for when polling is too slow.
kill -SIGUSR1 `pgrep autossh`
Kills a process matching program. I suggest using
$ pgrep -fl program
to avoid over-killings
Nice the following: kills all bash process owned by guest
$ pkill -9 -f bash -u guest
grep -- displays process ids
-v -- negates the matching, displays all but what is specified in the other options
-u -- specifies the user to display, or in this case negate
The process loops through all PIDs that are found by pgrep, then orders a forced kill to the processes in numerical order, effectively killing the parent processes first including the shells in use which will force the users to logout.
Tested on Slackware Linux 12.2 and Slackware-current
