What are the two ways you can execute a shell script when you do not have execute access permission for the file containing the script?
To do this you will need at least read permission; if you don't have that then you will not be able to execute the script at all. One way is to copy the script to your directory and add the execute permission. The second way is to call the correct shell interpreter program directly, as in: ksh /some/file/shell

I would suggest studying the source code of a current shell program to see how to go about implementing one of your own.
