Basic bash script

[Drew Sanderson]

Here is the output of ls -l from /Library/FileMaker\ Server/Data/Scripts/

-rwxrwxrwx@ 1 fmserver fmsadmin 73 Dec 5 15:17 touch.sh

This is the shell script:

!#/bin/bash

touch /Library/FileMaker\ Server/Data/Documents/touchtest.txt

This is the failure in the FileMaker server logs:

2011-12-05 15:26:59.389 -0500 Information 146 filemaker.hostname.com Schedule "touch" run now by "accountname [123.456.7.8]".

2011-12-05 15:26:59.395 -0500 Error 642 filemaker.hostname.com Schedule "touch" aborted; unexpected error. (-1)

This bash script is being called from a scheduled system script from FMS. Nothing else is attached to it like in a script sequence. I am using the default user ( FMServer ).

What am I missing that is causing this very basic script not to run?

[Karsten Wolf]

The shebang line start with #!

#!/bin/bash

touch /Library/FileMaker\ Server/Data/Documents/touchtest.txt

With that wrong the server doesn't know what to launch.

[Drew Sanderson]

I actually had that right but in a last ditch effort, I changed it to !# incase for some reason I had that wrong. I copied and pasted that line to the forum. oops. The error remain even with #! Any other thoughts? The script works fine from terminal. It really does not get any simpler than touch to test things out.

[Karsten Wolf]

Two ideas:

test from Terminal as user fmserver ( su fmserver ). Does that work?

What is the meaning of the @ in the ls -l output?

[Drew Sanderson]

I have no idea what the password of fmserver is.

[Drew Sanderson]

The "@" sign -- which is not documented in the manual page for ls(1) -- indicates that the file has extended attributes. You can use the command 'xattr -l <filename>' to show them.

On touch.sh that command returns:

com.apple.FinderInfo:

So you're editing with BBEdit ;-)

If you don't know what the root user is, stop here

To act as fmuser without knowing the pw:

- in a Terminal:

# going to root

su

# after entering pw

sudo -u fmserver /Library/FileMaker Server/Data/Scripts/touch.sh

That should execute the script as fmserver.

[Drew Sanderson]

The fmserver user was able to execute and create the touch file.

These are the steps I did in terminal. Notice I confirmed I was fmserver.

machine:~ user$ su

Password:

sh-3.2# su fmserver

bash-3.2$ whoami

fmserver

bash-3.2$ /Library/FileMaker Server/Data/Scripts/touch.sh

bash-3.2$

[Karsten Wolf]

When in doubt, RTFM.

The docs say you can set user & group for the script to run in. Perhaps using fmserver:fmsadmin is the error here.

I'm out of ideas and don't have a FMS to poke around here.

[Steven H. Blackwell]

The default fmserver account probably does not have privileges to do what the script asks. If creating a file, that file must be within the FMS security bubble. if it's outside, then it likely will not work. BTW, use something like the ChangeMOD utility to check the read/write privileges of the script file itself.

i was able to execute it under the fmserver user as revealed by my whoami I did just prior to executing the touchtest.sh as seen above in the thread so why would it be different if run under a scheduled script?

The file is being created in the "Bubble" at /Library/FileMaker Server/Data/Documents/

I did use chmod fmserver:fmsadmin on touchtest.sh The ls -l I placed higher in this thread shows the permissions are correct including that the file is executable. Again, I was able to execute it as fmserver when I used su.

What else might I be missing?

[Drew Sanderson]

When in doubt, RTFM.

I hear ya, but that thing lacks some serious detail. Amazing the details it lacks. It would also be nice if there was some more effective error communication to the logs!

[Karsten Wolf]

Have you checked the server drive lately?

[Drew Sanderson]

RAID Utility says that the status of each drive is "Good" but that SMART status is Unsupported. I had planned on doing a drive replacement soon. Tracking says the new drives are arriving today.

[Drew Sanderson]

Fresh OS and fresh FMS 11 and all weird behavior is gone.
