-2

What is the equivalent of this command in Solaris?

ulimit -e 19

What this does in other systems is set all programs in the current shell to run with nice -n 19. When I try to run the above command in Solaris it does not recognise the -e option.

    By "other systems" do you mean Linux? Becuase -e don't exist on Mac OS X nor OpenBSD. – thrig Feb 17 '17 at 1:14
  • I'm not sure why there are down votes. It seems to be a very normal and relevant question. – CJ7 Feb 20 '17 at 1:21

As I understand you want to define the maximum priority for the processes under a user. You can achieve this in Solaris via the prioctnl command.

prioctnl -s -m 19 -i uid $uid

I don't have a Solaris box at hand but the man page can be found here.

Also, if you want to make it permanent, the best way is to put it with a project. More info here.

  • I am not an administrator. Is it possible to run this command as a standard user to apply to the current shell? – CJ7 Feb 20 '17 at 1:18
  • it is possible, but it will depend on your rights. – BitsOfNix Feb 20 '17 at 7:13

I suggest that you Learn to use the renice command. You can do the same using the command:

 renice 19 -p <pid1 pid2 ... pidN>

In the local case running under a /bin/sh varient, use:

 renice 19 -p $$

this will change the nice level of the current shell to level 19.

  • I want to put the ulimit command in .profile so that it applies by default in every shell. What you are suggesting doesn't achieve this. – CJ7 Feb 17 '17 at 2:03

    @CJ7 It should do. The nice level is inherited from the login shell. – Kusalananda Feb 17 '17 at 10:10
