Hi, Is it possible to have a program start with a higher priority when you execute it from a shell? Specifically, I'd like to run C-Kermit at a slightly higher priority (read, it gets MORE CPU time). I find that file transfers sometimes fail/abort when I run a CPU intensive process while C-Kermit is transferring a file. This is on a 68030 NeXT computer running NextStep 2.0. This OS is BSD-ish and built on Mach.

[Maybe:]
$ mv program program_real
$ echo nice [some negative priority (only works for the superuser
though)] program_real > program
$ chmod +x program #+sx ?
anyway, "[only] The super-user may run commands with priority higher
than normal by using a negative increment, e.g., - -10." so watch out
for set-uid shell script temptations.
