I'm attempting to run GPG from cron, and it's not working. I can run the script from the command line, and all works perfectly. When I try to run it from cron, however, it doesn't work. The crontab calls this script, called "pgpdecrypt" with the following crontab line: > > > > > > > > > > */1 * * * * root /bin/bash /etc/pgpdecrypt > > > > > > > > > > The /bin/bash wasn't originally there; I added it to make sure that the script was using the correct shell.

The fact is that if you put the path at the beginning of the script, the script will run the same under cron as it does under the shell you tested it with. If the OP had put "#!/bin/bash" at the beginning of the script when he tested it, he would have been able to debug it without being confused by the fact that it ran under his shell and not under cron. Because the script ran under his shell but not under cron, he was deluded into thinking that the problem had to do with cron, and so he was looking for the solution in the wrong place. For several different reasons, it's better to have the executable path in the script instead of in the crontab. It's not that you can't get the job to run that way, it's just bad practice.
