#### Calling parm file.
. /psoft/batch/fsdev/scripts/parms/test_ae.parm
./batchae7: /psoft/batch/fsdev/scripts/parms/test_ae.parm[3]: cd: restricted shell - can't cd

./batchae7: /psoft/batch/fsdev/scripts/parms/test_ae.parm[13]: /psoft/batch/fsdev/log_output/grepfile.test_ae: restricted

Hi,

You either choose to use a restricted shell yourself (bash -r for example). In That case the solution is simple: Don't use the -r option

Or you are getting a restricted shell/environment by your Provider/IT department/School/etc/etc for security reasons. In that case: You are probably out of luck, but you can ask them if you could get an unrestricted/less restricted shell/environment (answer will probably be: No!).

Also have a look here: Restricted shell

Hope this helps.

Yes, you are using a restricted shell

rush shell => restricted user shell

Have a look here: GNU Rush

You don't, that is the point of the restriction.

Permissions can be a problem, but if I look at your original post I see this:

./batchae7: /psoft/batch/fsdev/scripts/parms/test_ae.parm[13]: /psoft/batch/fsdev/log_output/grepfile.test_ae: restricted
./batchae7: /psoft/batch/fsdev/scripts/parms/test_ae.parm[14]: /psoft/batch: restricted

All point to a violation of the shell and not a permissions problem.

Here a link to the rush man page. It does tell you a lot about what is and isn't allowed.

Hope this helps.
