How to get started
Hi, I just wanted to get started by following the tutorial at http://www.mactipscafe.com/tip015/ but I get the following error: 'Exec format error. Binary file not executable.' I did the chmod step as you can see below [:~/Desktop] xx% chmod 755 helloWorld.pl [:~/Desktop] xx% ./helloWorld.pl ./helloWorld.pl: Exec format error. Binary file not executable. Any help would be really appreciated. Thanks.
Re: How to get started
Are you sure you did step 3? It sounds like you ended up with something that isn't a plain text file.

Try, from Terminal perl -w ../helloWorld.pl The shell will ignore the shebang (#!) line and go directly to perl. The -w flag turns on perl's extra warnings. Also do a ls -l after you do the chmod to be sure the permissions got changed. It also wouldn't hurt to do cat helloWorld.pl just to be sure what you expect is there. If it has improper line ends or is in RTF format you'll see it. echo $PATH to be sure /usr/bin/ is in your search path which perl to be sure perl is actually installed. -- -- There are 10 kinds of people: those who understand binary, and those who don't --
Re: How to get started
Thanks, no it was something else, I had saved the file as Unicode-16 (UTF-16), once I saved it in UTF-8 it worked. It's one of those things you suspect right away but refuse to check because UTF 'should' always work, and if it doesn't, it's the fault of somebody else.

The shebang must be followed by a line feed, NOT a carriage return 3. The whole file will preferably be delimited with line feeds 4. It is not necessary to have either the shebang or exec permissions to run the script using $ perl temp.pl 5. To run it with ./temp.pl, the file must be executable 6. If you create the file in a text editor, make sure it is saved as plain text and with line feeds and not carriage returns 7. The only place where a line feed is absolutely de rigueur is immediately after the shebang. Here's something you can try step by step in the Terminal: xx:~ jd$ cd /tmp # go to the tmp directory xx:/tmp jd$# write a test file ... xx:/tmp jd$ echo '#!/usr/bin/perl print Hello\n ' temp.pl xx:/tmp jd$ cat temp.pl # check the result by reading the file... #!/usr/bin/perl print Hello\n xx:/tmp jd$ perl temp.pl # Have perl run the script Hello xx:/tmp jd$ ./temp.pl # Try running the script as executable -bash: ./temp.pl: Permission denied xx:/tmp jd$ chmod +x temp.pl # Make it executable xx:/tmp jd$ ./temp.pl # Try again Hello xx:/tmp jd$
