Using cat to write a file containing bash commands

Question

Consider the following bash scripts:

#!/bin/bash
cat << EOF > file
$@
VAR=`cat somefile`
EOF 

I want to write a file called file such that $@ is evaluated but cat something is not. In other words I want the output to look like this:

Arg1 Arg2 Arg3 Arg4 
VAR=`cat something`

If I use 'EOF' instead of EOF, then nothing gets evaluated, but I want $@ to be evaluated.

Answer 1

Have you tried escaping the characters? Using "\`":

cat <<EOF > file
$@
VAR=\`cat testfile\`
echo \$VAR
> EOF

Here is the file content:

cat file

VAR=`cat testfile`
echo $VAR

Then execute it:

./file
