I'm getting more comfortable with the terminal in Mac OSX and I thought I'd have a dabble at bash scripting. Not wanting to crawl before I could sit down I wanted to write an incredibly simple "Hello, world!" script so I did this:
~/Desktop touch hello.sh ~/Desktop vim hello.sh
I then added this to hello.sh
#!/bin/bash echo "Hello, world!"
I then did this:
~/Desktop chmod -x hello.sh ~/Desktop hello
At which point nothing happened.
I had downloaded an equally simple bash script from somewhere that was this:
#!/bin/bash echo "The current date and time." date
And when I did
it did exactly what it was supposed to.
So then I checked file permissions with ls -l and I got this:
-rw-r--r-- 1 Mike staff 33 5 Sep 21:13 hello.sh -rw-r--r--@ 1 Mike staff 50 5 Sep 21:00 date.sh
So clearly the @ is making all the difference, or so I thought. Instead of using vim I created the same file in TextEdit and after going through the same motions as before I ended up with the same situation, ie my script did nothing except now the permissions were showing an @ at the end of them.
So my questions are why is this not working, what am I doing wrong? And what is the @ at the end of the permissions?
