Re^3: I come in peace for I seek your wisdom dear monks :)

What I said is true and I think that I covered your case with:

Once you have given execute permission to the file, you can just type "helloword.pl" and it will run. Typing "perl helloworld.pl" explicitly starts the Perl interpreter and sends it the helloworld.pl file.

In the above, yes, "perl helloworld.pl", helloworld.pl does not need execute permission because helloworld.pl is an input file to the command "perl". Normally one would give the .pl file execute permissions and omit the need to type "perl" explictly. Note: On Unix the "file extension" of .pl doesn't matter. On Windows, there are a couple of non-obvious steps required to get a .pl file to execute in all situations without having to type "perl" first. But that is not the question here.

If the OP cannot execute the .pl file, either the OP is in the wrong directory or has the wrong permissions or has the wrong shebang line or the path does not have the perl command.

My advice of:

Get helloworld.pl working in your default login directory before trying to move it or get it to run in a sub-directory.

still appears solid to me.

Typing "perl helloworld.pl" explicitly starts the Perl interpreter and sends it the helloworld.pl file. You said it was required to set execute permission. It isn't. Now the phrasing of the lines above is such that for someone unfamiliar with permission bits, it still looks like "perl helloworld.pl" requires execute permission. Also note that you can just type "helloword.pl" and it will run only works if either `.` (a dot) or the path of your current directory is in your $PATH. Given the example case from the book, the latter is very unlikely - and putting `.` in your path is usually strongly adviced against.	[reply] [d/l] [select]
