I have a function which required some process ID that needs further action.
I tried to get it via command
PID = $(ps axf | grep SOME_PATTERN | grep -v grep | awk 'print $1')
And it works on ubuntu and centos, but doesn't work on suse.
Although manually it works everywhere.
What could be the reason for the specific works on Suse and how can I fix it?
linux grep opensuse ps suse

You cannot have spaces around=in a variable assignment.

You need to use pgrep instead of ps axf if you want to use it with watch command. There is more extended explanation here
