I am trying to do approximately this in a crontab: SHELL=/bin/bash 0 8 * * * prog >/tmp/$(date +%s).extension
and it doesn't work, the command never gets executed. Backtick substitution doesn't work either. An identical command with a fixed string in place of the $(date +%s) command substitution works perfectly. An identical command executed on the command line works perfectly. Anyone have any guesses as to what might be going on here? Britton Kerin __ GNU GPL: "The Source will be with you... always."
