dirname not working in 'at' spawned script

[rdp010]

I have a script which shells itself. Within the script is
a command ADWENV="${ADWENV:-$(dirname $0)/adwenv}". This command works okay if the script is submitted via cron, but during the execution of the script from the 'at' scheduler it abends. UX:sh: ERROR: /ADW/dev01/bin/rdp-shellself1.sh: $(dirname: not found

Anything run by [tt]cron[/tt] or [tt]at[/tt] runs in a bourne shell ([tt]/bin/sh[/tt]). It also doesn't run your [tt].profile[/tt], so environment variables you are expecting to be there might not be.

You need to make sure you have a...
[tt]
#!/bin/ksh
[/tt]
...as the first line of your script. Also, you can either add a...
[tt]
. ~/.profile
[/tt]
...as your next line. You can also change that line to look like...
[tt]
ADWENV="${ADWENV:-$(/usr/bin/dirname $0)/adwenv}"
[/tt]
There are other things you can do, but this should get you started.

Hope this helps.
