In reply to Thanh Phong. Sorry, the acutal command is:

# echo Host * | grep "Host \*$" not work !!

Your first example is an awesome choice! It’s exactly what I came here looking how to use grep to do.

The example number 2 is is VERY WRONG.

# grep -v “#” /etc/apache2/sites-available/default-ssl

will also exclude lines like: value display_errors off; # turns off errors right way to this is:

# grep -v "^#"  /etc/apache2/sites-available/default-ssl
so it will exclude only lines that begins with #.
