I don't like it but one workaround is to immediately modify line 1 of the newly spooled job.

So that strategy would be to write a wrapper on top of
intercepts its $jobid when Not needed
at is run underneath
- changes the shebang shell line of the newest file in /var/spool/cron/atjobs/ :
sudo <<< 'cd /var/spool/cron/atjobs/ && sed -i -e "1s/\#!\/bin\/sh/\#!\/bin\/bash/" $(ls -1t |head -n1)'
Might be a race condition in case of the
at now by-itself timespec, unless perhaps additional time (like 1 sec) is artificially added. Though in my own use cases, I really need it run now not in 1 sec.
Anyway that's too much of a system hack to comfortably make my scripts use.
