Hello David I know that is not an elegant way, but you could try to execute a script calling another one I don't know if will works, but you can try.
#!/bin/bash nohup caffeinate -s bacula-idle-watch.sh >/dev/null 2>&1 </dev/null & exit 0 Best regards *Wanderlei Hüttel* http://www.bacula.com.br Em seg, 7 de jan de 2019 às 17:06, David Brodbeck <brodb...@math.ucsb.edu> escreveu: > Hmm, good catch on the redirect, but it still doesn't work.
