How to send SIGINT to multiple processes I am trying to send the SIGINT signal to multiple processes, I think this is right: kill -2 <pid1> <pid2> ... <pid3> but I cannot confirm that...

Yes, this is right. The man page confirms it. Running `man kill` says:


SYNOPSIS
kill [options] [...]

...

OPTIONS
[...]
Send signal to every listed.


Your shell probably provides its own internal version of `kill`, which will take precedence, but it should be compatible with the interface described. You may be able to find more info by running `help kill`.

I'd use `kill -INT` instead of `kill -2`, since the name-to-number mapping can vary between UNIX variants.
