I'm really new to Perl, so my question is probably going to sound real stupid. Anyhow, I am reading "Learning Perl" by Randal Schwartz (AKA "The Llama Book") and I am trying to run my first simple program using Terminal. Here's the program: #!/usr/bin/perl print "Hello, world!\n"; I put these lines in a text editor (in BBEdit, actually). The book said to then enter the following command (I'm not sure if Schwartz meant within Perl): $ chmod a+x my_program Then, enter this command: $ ./my_program Now I had tried running this in Perl in Terminal and it gave me this message: "Bareword found where operator expected at - line 1, near "$ chmod a" (Missing operator before a?)" Am I doing something wrong? I also have the document on my Desktop. Am I not supposed to have it there? Also, Schwartz mentioned something about not having an extension on the text file. I don't see any, but should I change it to .plx anyway? Any advice? Thanks in advance from an aspiring Perl programmer.
