Bash scripts requiring sudo password

Question

I\'m creating a Bash installer script which compiles and installs some libraries for both OSX and Linux. Because some commands in my script (\"make install\", \"apt-get install\

Answer 1

To get the password, just put sudo echo "Thanks." at the start of the script.

But I would prefer this solution:

if [[ $UID != 0 ]]; then
    echo "Please run this script with sudo:"
    echo "sudo $0 $*"
    exit 1
