Bash Question: HowTo Exit Script with User Input While Process is Running Mid-Loop?
Hi, I have written a script that allows me to repetitively play a music file $N times, which is specified through user input. However, if I want to exit the script before it has finished looping $N times, if I use CTRL+c, I have to CTRL+c however many times are left in order to complete the loop. For instance, if I specified that the song is to repeat 5 times, if during the first iteration through the loop, if I use CTRL+c to exit the script, I will have to press CTRL+c four more times before the script will terminate.
My objective is to be able to type 'q' or some character in order to quit the process. I have found limited information about this topic online, and what I have found has not worked for me.
Although my script provides more options than what is listed below, here it is in its most basic form (note - I'm using mplayer to play the audio file):
Does anyone have any recommendations on how I can exit from the script using keyboard input in such a way that I'm not stuck in the loop and that the script actually terminates?
