Stupid question. Did you type "y" or "n" (then <enter>) at this point?

it still gives an error when a add a "$" on either side of the read variable, my if statements have been working without them too, just now it gives me an error.

Sorry the $ signs were from my editor. I have removed them from the post.

What I was wondering was whether the script asked the question and whether you could reply with "y" or "n" .

currently, I get an error before I get a chance to say yes or no. The script stops and gives me an error at the line
Code:
echo "Have you completed the requirements and still want to continue?"
echo
echo "y/n?"

As soon as it dislplays' y/n, it stops and gives me the error
Code:
./ad2.sh: line 66: [: = unary operator expected
./ad2.sh: line 144: [: = unary operator expected

Please post the current version of the script.
We assume that you have now sorted out the multi-line "echo" statements (which do not work in every Shell) and of course the quotes in:
if [ "$variable" = "something" ]
statements which stops the condition being erroneously treated as a numeric compare.

Btw. This will be a lot quicker if you post the exact script, what you typed, and exactly how the script replied verbatim.

I updated it awhile ago, check back on page 2, i told you i updated it. Secondly the echo issue does not need to be addressed because there was a point where the script worked with those statements.
Thirdly, i am not quoting the if statements becuase it was working before.
Also othr iphone scripts do not use the quotes.

There must be another issue.

Can anyone help me? I am getting kind of depressed...

Have you tried using the "set -xv" to see what is throwing the error ?
