[foxboro] Starting scripts from cron

Sebastian,

Usually in these cases the cause for the problem is to be found in the
environment. Make sure, that your script is run in the same shell as =
you
tested it with (usually I use the bourne shell so the first line in my
script is "#!/bin/sh").=20

Try a test script, which just dumps the environment in some file in =
your
test shell and then start this from crontab (remember to rename the =
output
file between the two tests. ;-)

E.g. (untested, maybe "printenv" is in /usr/bin)

#!/bin/sh
/bin/printenv >/usr/tmp/myenv

Examine the differences of the two outputs. Often it's a missing PATH =
or
DISPLAY variable in cron jobs.

Hope this helped.
