Whats up with this basic script??

I run it using ./tester.sh and I get the output: Quote:

Am I seriously doing something fundamentally wrong here? Shall I consult a doctor because my IQ has now dropped to equal a squashed watermelon? Someone help! |
For starters, where did you get "debug"? It is not on my system or in my distro repositories (Arch).
Is it intended to be used with BASH scripts? What happens with: debug -x ./tester.sh OR: debug ./tester.sh ? |
Sorry its the way I typed it.
I meant I ran the script in debug mode using: sh -x ./tester.sh I know there is nothing called debug. |
Aha!!
OK--what is "sh" on your system? Is it aliased to BASH? |
yeah I am using /bin/bash
The script works perfectly. But when I check "under the hood" in the debug mode it is complaining. I have never come across that before so am wondering whats going on. I have tried it on 2 other machines and still the same error. So cant be me... can it? |
On my system, "sh" is a softlink to bash
Code:
[mherring@Ath ~]$ more debug |

This: echo $SHELL is not reliable to show which shell is used: Quote:
What does sh --version tell you. BTW: I, like pixellany, don't have any problems with the "problem" you posted. |
Shells that don't like this kind of function declaration are Ash, Bsh, Csh and Jsh (as in checking for odd shell linkage which clearly didn't happen anyway). However the exact "tester.sh: 1: function: not found" error I can only reproduce using /bin/bash when 0) invoked as 'sh' AND 1) removing the "function" from the "function Output" line. (The other shells will spit out other types of errors.) Which is odd as with current Bash-2 you wouldn't even need to explicitly use the "function" tag to declare a function as "name() { doSomething; }" will do easily...
//BTW with my systems I didn't see no errors either. I wonder though what doctor could help the OP ;-p |
Ooooh weird...
On all my Ubuntu systems I get the same results: Quote:

I can't test it right now to duplicate the error I think it's complaining because the function doesn't have anything to do. It looks at the Output line at the bottom for something to plug into the function and doesn't find anything. Try:
function Output { echo $1 $2 } Output Hello World Output Good Bye Output One Two A function performs the action between the brackets on every line you have listed below it with the variables ($1 $2 here) being substituted in the function. So this runs echo $1 $2 on the line "Hello World" then runs echo again on "Good Bye" then runs it again on "One Two" etc. |
Interesting, about using dash for /bin/sh. At least the results can be explained now. To tell you the truth it is the first time I've heard of it. There is a wikipedia article on it. Looks like Debian and Ubuntu have this as their default for /bin/sh.

Well nevermind, I should have read the thread more carefully and tested the original function first. I ran it and it doesn't give any error here either.
