I am innocent of this crime. I used normal single and double quote in the code. But WordPress converts them into those fancy html quotes.

And thanks for the other pointers – especially…
> contents=$(< Hello.sh);
This will come in handy.

First of all, please consider posting normal quotes in code. Funny html-quotes may look nice, but bash does not understand them and so we have to change them by hand (which is rather annoying

Now to the actual code ..

If you know how many iterations you need, the “for ((i=0; i contents=`cat Hello.sh` #For some reason, I’m losing all the \n’s in the file.
> echo “Hello has `echo $contents|wc -m` chars” # Or wc -m Hello.sh

contents=$(< Hello.sh); # You won a “useless use of cat”-award
echo “Hello has $(wc -m << string=”Hello World”
> evil=`echo $string | grep ‘^Hell’`
> if [ "$evil" != "" ]; then
> echo “Yup – its evil”
> fi

string=”Hello World”
if grep “^Hell” << echo “Hello World” | sed -e ’s/l//g’ #Will return Heo Word

echo “${string//l/}” # assuming $string is still valid

Cheers, Emil
