The watch
command is documented as follows:
SYNOPSIS
watch [-dhvt] [-n <seconds>] [--differences[=cumulative]] [--help]
[--interval=<sec-onds>] [--no-title] [--version] <command>
[...]
NOTE
Note that command is given to "sh -c" which means that you may need to
use extra quoting to get the desired effect.
The part about giving the command to sh -c
means the jobs
command you are running via watch
is running in a different shell session than the one that spawned the job, so it cannot be seen that other shell. The problem is fundamentally that jobs
is a shell built-in and must be run in the shell that spawned the jobs you want to see.
The closest you can get is to use a while loop in the shell that spawned the job:
$ while true; do jobs; sleep 10; done
You could define a function in your shell startup script to make that easier to use:
myjobwatch() { while true; do jobs; sleep 5; done; }
Then you just have to type myjobwatch
.
2I add a
clear
.N=1; while true; do jobs; sleep ${N}; clear; done;
