RunExternalM2 :: PreRunScript

PreRunScript -- a way to impose resource limits


This option's value is a string containing a shell command that can impose any resource limits on the Macaulay2 process started by runExternalM2.

By default, it is set to the shell command


but you can set it to things like

ulimit -t 5

(to limit CPU time to 5 seconds) or something more complicated:

ulimit -S -m 654243 && ulimit -H -t 50

In all cases, it should be a single command such that appending

&& other_command

results in a valid shell command.
