Linux - Signals

In Linux, there are lots of signals that we can send processes. These signals are labeled with names starting with sig. Remember the sig.int signal we talked about before. You can use sig.int to interrupt a process and the default action of the signal is to terminate the process that’s interrupting. This is true for Linux too. You can send a sig.int signal through the keyboard combination control C. Let’s see this in action.

I’m going to do the same thing as we did in Windows and start a program like sudo parted. Pasted image 20260623195537 We can see that we’re in the parted tool now. Let’s interrupt this tool and say we want it to abort the process with a control C keyboard combination. Pasted image 20260623195609 Now we can see that the process closed and we’re back in our shell. We were able to interrupt our process midway and terminate it.
