`watch` command with piping `|` [duplicate]

`watch` command with piping `|` [duplicate]



This question already has an answer here:



I want to keep monitoring a specific job on a slurm worload like cluster. I tried to use the watch command and grep the specific id. If the job id is4138, I tried


watch


grep


id


4138


$> watch squeue -u mnyber004 | grep 4138
$> squeue -u mnyber004 | watch grep 4138



but they doesn't work. The second command works for the first few seconds, but stop working when watch refreshes.


watch



A better idea please?

You have to quote the command


watch 'squeue -u mnyber004 | grep 4138'



The other answer covers how to handle using the 'watch' utility with a pipe but since you're using Slurm and know the job ID, just ask Slurm for that job's status:


$> watch squeue -j 4138





It works well too. thanks
