How to terminate while loop.
 

Hi

I started a while loop directly from terminal to read a file line by line and to run a command on each line. Post running the command I realized to modify the command and tried to stop the loop by using CTRL+C but it didn't stop. I closed that terminal directly but loop is still running. I also tried to KILL the process but it is getting started automatically with a new PID. Please suggest to stop this loop.

Thanks.

kill the parent process, probably a bash shell.

How did you start the while loop?

What I did is I searched the PID for the command running on each line and killed the same. Please suggest, how to kill parent process.

while read line
do
ldapsearch $line
done < filename

pstree -p will show the parents with their PIDs

Use the pstree command to find the parent process, e.g.
specifying your username to reduce the output.

Hi Charles! :)

It's not obvious why that doesn't respond to multiple Ctrl+C signals, unless the ldapsearch command is programmed to ignore SIGINT.

EDIT: and doesn't exit

Have you tried to rename or move filename?

Hi colucix :)

We keep doing that, one way round or the other

Hi colucix

I killed the parent process but process is still running with a new parent ID.
Also tried to move the filename.

Try killing the parent's parent

Killing the parent process, didn't help.

Assuming you are not logged on as root, try killing the parent's parent and, if that doesn't work, the parent's parent's parent

AlsoCould we see the culprit script?

If it is not a live system, then shutdown -h now or shutdown -g0
`

OK.
