I have come to know that we can use watch command to monitor the output of other command and it prints the output every 2 seconds by default, which is really useful.
I start to use it to monitor the output of nvidia-smi, for example. But now I do not know how to quit the program (stop monitoring the output of nvidia-smi). I tried to press q and there is no response.
Searching the internet with similar title gives me no clue. There are only some tutorials on how to use watch and its options and I can not find a way to stop the command. I am stuck here.

From man watch:
By default, watch will run until interrupted.
The key words are "until interrupted", which basically can be interpreted as until (but not limited to) the following happening:
- The user (you) pressed CTRL+C in the terminal.
- The system restarted.
- The process was issued a
killrequest.

I am curious to know why there is no shortcut to useqto stop watching, just like when we are usinglessormancommand. A lot of command support the use ofqto quit.

I am not one of the programmers and I can not answer for them. As far as I understand, the source code forwatchis available and you should be able to either fork it and create your own version that includes the option to pressQto quit or extend it like others have by submitting a patch or getting directly involved in the program development.

@Hao, note that reacting to a signal (generated by Ctrl+C) and reading tokens fromstdinare very different code paths.lessandmanaccept a variety of keystroke commands;qis just another among several.watchaccepts no keystroke commands, so it would be functionality added only for quit.

@Hao, note that reacting to a signal (generated by Ctrl+C) and reading tokens from
stdin are very different code paths. less and man accept a variety of keystroke commands; q is just another among several. watch accepts no keystroke commands, so it would be functionality added only for quit.– user4556274
