I am running a cron job to remove log files that reach a certain size.  On the IRIX OS, this is no problem.  However, the command I'm using (npri) doesn't exist on the SUNs.  What can I use instead?

`npri` is used to set the priority of a process; The equivalent command under Solaris would be `nice` or `renice`

Yes, that should work, you can specify how nice (1-19) you want to lower the priority of the job by
nice -n 19 ...
to make it really low priority, the default is 10

Equivalent command is called priocntl ( defeating process aging, setting fixed high or low "pri" value etc) , but "nice" is posix utility and suits your application perfectly.
