Exit command with any key

rated 0 times [ 1] [ 0] / answers: 1 / hits: 644 / 3 Years ago, sun, august 1, 2021, 8:24:54

Here's what I have:

A script that records sound and exits when pushing ctrl+c

arecord -D plughw:0,0 -f cd -t wav -d 0 -q -r 16000 > file

This will record and record until I push ctrl+c

I want to simulate the ctrl+c action, by pushing any key (preferably one keystroke)

You can use stty in a subshell and change the setting for ctrl-c to whatever. In my example I changed it to x. After the subshell is ended or interrupted by x the setting will be restored to ^c (ctrl-c).

user@host:~# (stty intr x && arecord -D plughw:0,0 -f cd -t wav -d 0 -q -r 16000 > file); stty intr ^c

Even if you kill the process via killall acroread the setting will be restored.
