shell script doesn't run

Igor Sovin — Tue, 05 Sep 2006 22:23:55 GMT

Hi!

I have priblem running script which starts with
#!/bin/sh.
When I run it as root it works fine, but it doesnt run under another user, although all permissions are set correctly.

here is ls -l:

kate:oraslp 7> ls -l

R3COPY is the script that I told about.

First, your shebang should be /usr/bin/sh not /bin/sh. Secondly, while the permissions of the RCOPY script/program are ok (and I question if this should be executable by anybody -I would change the mode to 750 rather than 755), it's probably the permissions of some other commands/executables/files/directories within the script itself that is the problem. I would add a "set -x" near the top of the RCOPY script and that should tell you where the script is failing. This applies if R3COPY is a script; if it is a true executable then run it under TUSC to see where the error occurs.

It really helps when you post the exact error message; otherwise, I have to use "The Force".

Apparently it is not a problem with the protection of the script, but with priviliges needed for an action triggered by the script.

Are all environment variables in place before the run

- What is the exact error message?
- How far does it get in the script?
- Run it with debug output ( -x ) ?
- 'diff' output form env for root and for the other user?
- Cut & paste individual commands from the script and try them?

Sounds like the script want to copy Oracle files around. Doe the other user (oraslp?) have write privs for the target? read privs for the source?

You can figure this one out!
We know you can!

Good luck,
Hein.

Hi guys!

However, I dont get any error after starting script. It simply does nothing:

kate:oraslp 6> ./R3COPY
kate:oraslp 7>

Setting the "set -x" also didn't show any error.

Could you attach the script so that it can be looked at?

thanks!

Hi!

The script is in attachment

I looked at your script, at first sight there
seems nothing out of the ordinary.
There are a couple of exit conditions like
ORACLE_HOME not set, or Oracle not available etc.. , but then you should see an error produced by the script onto your terminal.

So the fact that you get no output at all looks like a fork or exec problem.
Possibly due to something in the environment
But in all honesty I can't explain it yet.

When you run the script like this

oraslp>sh -xv R3COPY

You do not get any output at all ,
not even the verbose info?

By the way this oraslp it is a cshell or not ? And what are your terminal settings ?
When you do ps -ef | grep -i R3COPY is it still in memory ?

Hope we can move on from here.

Igor,
1. Are non-root users allowed by directory to run the file?
2. Check the shell:
ll /usr/bin/sh [ -r-xr-xr-x ]?
3. Change your first lines:
#!/usr/bin/sh
echo hello
exit

Frank,

here is the output of sh -xv:

oraslp is a cshell user.
ps -ef |grep -i R3COPY shows that process not in memory.

Peter,
1)Permissions on /usr/bin/sh is correct
2) After changing first lines i see "hello" in the output, it work fine.

Ah, we can see now where and why it exits.

It says that no option was passed to the ksh shell and exits.

Before you run the script,
can you first type ksh
at your cshell prompt of oraslp.
And then run the script again.

Let me know if that does it,
Also in combination with the ksh shell you can change the first line in your script to #!/sbin/ksh

If this does not work I need to do some research on this interactive shell thing; but we are getting closer :) :)

Re: shell script doesn't run

Igor Sovin — Thu, 07 Sep 2006 04:54:47 GMT

Okay

kate:oraslp 3> ksh
kate:oraslp> ./R3COPY
kate:oraslp>

Unfortunetly no result.

Re: shell script doesn't run

Igor Sovin — Thu, 07 Sep 2006 04:59:32 GMT

but it runs when I change the first line in my script to #!/usr/bin/ksh

Re: shell script doesn't run

Bill Hassell — Thu, 07 Sep 2006 19:40:51 GMT

It's important to know why /usr/bin is the correct location. In HP-UX (and other SysV Unix flavors like Solaris), the /bin directory no longer exists. To verify this, type the command:

ls -ld /bin

It is not a directory but a temporary link so script writers can change their interpreter line (#!/usr/bin...). Linux and other BSD versions still use /bin so it is important to remember the differences. /bin has not existed for more than 10 years in HP-UX.

Since the set -x did not work, the script did not run. The alternate method is to to place the -x trace on the command line as in:

ksh -x ./R3COPY
