Bash script to find and kill a process with certain arguments

bashprocess

I want a script which kills the instance(s) of ssh which are run with the -D argument (setting up a local proxy).

Manually, I do ps -A | grep -i ssh, look for the instance(s) with -D, and kill -9 {id} each one.

But what does that look like in bash script form?

(I am on Mac OS X but will install any necessary commands via port)

Run pgrep -f "ssh.*-D" and see if that returns the correct process ID. If it does, simply change pgrep to pkill and keep the same options and pattern

Also, you shouldn't use kill -9 aka SIGKILL unless absolutely necessary because programs can't trap SIGKILL to clean up after themselves before they exit. I only use kill -9 after first trying -1 -2 and -3.

Try to use pkill selenium if neither this, nor one of the others work you can keep using your method with another pipe sequence such as

kill `ps -ef|grep -i selenium| grep -v grep| awk '{print $2}'`

Bash – How to run a program multiple times with different arguments using a loop in a bash script

To simply run the program ten times, with the (incremented) iteration number as an argument, do this:

for ((i=1; i<=10; i++))
do
    python script.py "$i"
done

As Kamaraj says, to get the ten processes to run at the same time (i.e., simultaneously / concurrently), add & to the command:

for ((i=1; i<=10; i++))
do
    python script.py "$i" &
done
