I had the chance to try out these options. *YiFei *was right in that the scripts, when invoked by crontab after zsh was activated, were being invoked by sh and that was why the *source* command was not working.
Using . (dot) would resolve the issue on command line, but I cannot tell jsub to use dot. My current crontab entries look like this: jsub -N "h" -once -o ~/err/hourly.out -e ~/err/hourly.err ~/grid/jobs/hourly.sh But neither of these are allowed: jsub -N "h" -once -o ~/err/hourly.out -e ~/err/hourly.err . ~/grid/jobs/hourly.sh jsub -N "h" -once -o ~/err/hourly.out -e ~/err/hourly.err ". ~/grid/jobs/hourly.sh" The first one causes jsub to find two arguments and crash; the second one causes jsub to complain that ". ~/grid/jobs/hourly.sh" is not a program. *Roy Smith* offered a trick to explore what environment was used when my script was run. So I create a small script with content "/usr/bin/env > ~/myenv.jsub.txt" and then asked jsub to run it. The job was successfully submitted, but myenv.jsub.txt file remained empty! It is as if *no* environment was passed, which is confusing. Anyway, for now, I have given up on `exec zsh` and am going to just invoke zsh manually after I run `become`.
