Create a shell script with a shell script

Question

I'm creating a script which create file and insert content using

cat > /etc/file <<END
FILE CONTENT
END

It works for most files but it doesn't work when file content have shell commands in it. I tried with the echo command but i have the same problem.

Why does it execute commands ?

If the here-doc contains `$variable`, the variables will be expanded. You need to use `<<'END'` to prevent variables from being expanded. — Barmar, Jan 12 '15 at 10:29
Correct ! I had to use backtick escapes to solve my problem, my script contains variables wich were executed. How does i set your answer as valid? Thanks by the way — Rck, Jan 12 '15 at 10:41

The file's content includes $variables wich are expanded. To avoid variable expansion, I had to use single-quote escapes 'END'.
