How to kill a running for loop on linux?

Question

I'm working on Linux, I have executed the for loop on a Linux terminal as follows:

for i in `cat fileName.txt`
do
echo $i
vim $i
done

fileName.txt is a file contains the large no of file entries that I'm opening in vim editor one by one. Now i have to skip opening other files in between.(i.e. i have to break the for loop). Any suggestion how to get the PID of running for loop? and kill the same. Thanks in advance.

Solution 1

You want to kill the running job. Press CtrlZ. Bash will show something like:

[1]+  Stopped                 vim $i

Use that number with kill to send the KILL signal:

kill -9 %1

and it should be killed afterwards:

[1]+  Killed                  vim $i

Solution 2

This might also do the trick:

while true ; do killall vim ; done

You can abort this one with ^C as usual.

Solution 3

Find the process id (PID) of the parent of the vim process, which should be the shell executing the for loop. Try using "pstree -p". Then, kill that process id using "kill ".
