Change: “check distro” – put in how to check kali in /etc/???

Check which Debian install you have:

lsb_release -a

echo $var             # is the same as...
printf '%s\n' "$var"

echo -n $var          # is the same as...
printf '%s' "$var"

Basic Syntax:

find /path/to/search/ -name searchTerm

If you get a bunch of garbage on the screen, send it all to /dev/null:

find /path/to/search/ -name searchTerm 2>/dev/null

tar xvzf filename

# x - extract
# v - verbose
# z - zip / gnuzip
# f - file (name follows)
