How we can change the priority of a process with top command in linux?

Question

I want to change the priority of a process using top command

perhaps you meant htop? top and htop are two different tools and htop can indeed change priorities — AnonymousLurker, Nov 28, 2018 at 4:50

Once given top command, press r. Give PID value of the process you want to change the process value. Give renice value (from -20 to +19)

Nice value of -20 means highest priority value and +19 means lowest priority value. 0 is by default value.

Don't confuse renice value (-20 to +19) with process value (0 to 39)

relation between nice value and priority is :

PR = NI + 20

In addition to erTugRul’s answer, the renice command exists for this exact function.

renice -5 -p 1234
