Shell Programming and Scripting

I have a script at /java/custom/build.sh

I want to force the user to execute the script from the /java/custom directory ONLY. In other words if the user is in /java I want to exit if they execute custom/build.sh

The directory structure may change from the env to env, so I can't use variables (say $SCRIPT_PATH=/java/custom).

Thanks for the help in advance

I am not sure how to tell what directory the script is currently residing in, but PWD will tell you the directory that the person who is running it is in. er, hope you understand that. ^_^

Code:

#!/bin/bash

if test $PWD != '/java/custom'; then
        echo "You can not run the script from any directory except /java/custom";
        exit 1;
fi

something along these lines:

Code:

#!/bin/ksh

iam="$(whence $0)"
iamDir="${iam%/*}"
iamDir="${iamDir%/.}"

if [ "${iamDir}" != "${PWD}" ]; then
  echo "you cannot run [${0}] from anywhere BUT [${iamDir}]"
  exit 1
fi

echo "I'm happy"

Wish it was that easy, Like I said the directory structure may change from env to env so I can't use $PWD against a predefined path. It has to be generic.

Thanks, vgersh99

That's exactly what I was looking for.
