As always, thanks. I checked the change in to GIT -- I learn something new every day ! ...Phyllis
CPUS=`nproc`
Is that correct?
Yes, please change it to CPUS=nproc
The single quotes are not needed, those are to prevent shell expansion within the quotes.
Attention, it is absolutely not the same, whether in backquotes or unquoted. Backquotes mean that the shell tries to execute the quoted contents as a command and substitute the standard output of that command as the result.
Please compare and see the difference:
mri.sge:~>nproc 2 mri.sge:~>CPUS=nproc mri.sge:~>echo $CPUS nproc mri.sge:~>CPUS=`nproc` mri.sge:~>echo $CPUS 2
(there are 2 cores on the test computer, mri.sge:~> being the shell prompt)
