I wrote a shell-script for a unix-maschine (Unix IBM AIX 4.3.2) and i used
the wait command.

When i start the script from the command-prompt everything works all right.
but if i start it with the cron -job the following problems appear:
1) the sub-shells were not started
2) the wait command was ignored because 1) (i think so ;-))

Please can anybody help me a.s.a.p.?????????
(our data-secure does not work)

Thanks

Maybe you have some kind of pre-requisite for a terminal in your
sub-shell actions : just try to re-direct both stdout & stderr in your
cron command. If this is not enough, try to redirect stdin too (but is
needed only in some wierd cases).

Hope this helps,
Patrice.

Are you properly defining FULL path for all executables in the script?
It is possible the script works on command line because your shell has
the PATH variable defined where crontab doesn't. Another LESS gracefull
dirty workaround is to add the sourcing of your login file or add the
PATH declaration to the top of the script.
