Very Computer

I am initiating a shell script that goes out to various UNIX hosts to
get system info.  I want to run the shell as bourne shell for the sake
of uniformity.  

I initiate a shell script#1 on the local host.  Script#1 will do an rsh
to the remote host, the remote host will mount itself to the local host
and then call another script (script#2) that resides on the local host.  

The default ROOT login for the remote host is /bin/csh.  The problem is
that when i login to the remote host it will not read the script that
has been written in bourne shell.  At the beginning of script#1 and
script#2 i use the "#! /bin/sh" syntax.  
The remote host will not read the       if [ ! -d $MOUNT_PT ]
                                                then  
                                                /bin/mkdir $MOUNT_PT
                                                fi

The errors that i get are as follows:

Remote: csns2
Missing ].
then: Command not found.
mkdir: /admin_mnt: File exists
fi: Command not found.
MOUNT_PT=/admin_mnt: Command not found.
export: Command not found.
HOST=csns2: Command not found.
export: Command not found.

I would appreciate any help that I could get.  I did read the
comp.unix.shell FAQ and did see some differences btw. csh and sh but
could not seem to get an answer to my problem.  
Thanks in advance.

If you want to perform the test, you may do it like this:
      [ -d $MOUNT_PT ] || /bin/mkdir $MOUNT_PT

Both solutions will solve your problem.

| Err... just a first glance but shouldn't that test have a semicolon after
| it? All mine do....
| if [ ! -d $MOUNT_PT ] ;
| then  
|     /bin/mkdir $MOUNT_PT
| fi

If you have access to a UNIX computer, give it a try.  ";" is a logical
end of line, and at end of line it's redundant.

I don't see anything wrong with the syntax - it's conceivable that some
shell implementation could have trouble with  "test ! -d xxx", but in
practice I think all can handle that.  To test that, reverse the sense
of the test -
  if test -d $MOUNT_PT
  then
       :
  else
       /bin/mkdir $MOUNT_PT
  fi

Assuming syntax is OK, and assuming MOUNT_PT is defined as expected
(verify this using "echo"), we have to assume the poster's surmise is
correct and root is executing the script with csh.  (It would eliminate
a lot of useless speculation if people would post the actual error
messages if any, rather than using terms like ``the remote host will
not read''.)  One thing to verify is that the script is chmod +x and
the #!/bin/sh line is right at the top.
