Question

In a bash script I execute a command on a remote machine through ssh. If user breaks the script by pressing Ctrl+C it only stops the script – not even ssh client. Moreover even if I kill ssh client the remote command is still running…

How can make bash to kill local ssh client and remote command invocation on Crtl+c?

A simple script:

#/bin/bash ssh -n -x root@db-host 'mysqldump db' -r file.sql 

Answer 1

Eventual I found a solution like that:

#/bin/bash ssh -t -x root@db-host 'mysqldump db' -r file.sql 

So – I use ‘-t’ instead of ‘-n’. Removing ‘-n’, or using different user than root does not help.
