I have numerous variables within different php files, and I just want to list them in my terminal.

I guess the command begins with 'cat file.php file2.php' and ends with '| sort | uniq' but I failed finding a pattern that matches a variable, and I have no idea how to cut them from the rest of the line..

Thanking you in anticipation

You could try this:

egrep -o '\$\w+' *.php | sort -u

Variables start with $ and are followed by alphanumeric charaters.
