/bin/sh^M: bad interpreter: No such file or directory

Error Message

The following error displays upon running the startJavaHelp script:

"./startJavaHelp: <install path>/arcgis/java/docs/startJavaHelp: /bin/sh^M: bad interpreter: No such file or directory".

Cause

The UNIX shell script 'startJavaHelp' is in a DOS format, and the file contains ^M line returns.

Solution or Workaround

1. cd to <install path>/arcgis/java/docs/startJavaHelp
   
2. Determine the owner <username:group> who installed the ArcGIS Engine Developer Kit and make a note of it:
   ls -l
3. Log in as root:
   su
4. Run the 'dos2unix' utility:
   dos2unix startJavaHelp startJavaHelp
5. Change the owner of the 'startJavaHelp' script from 'root' back to the user who installed the ArcGIS Engine Developer Kit (as determined in step 2). For example, if the <username:group> is <test:users>, then execute:
   chown test:users startJavaHelp
6. Change the file permissions to 555:
   chmod 555 startJavaHelp
7. Exit root and run the script as normal.
