Bash quoting example

gistfile1.sh

#!/bin/bash

function my_print() {
    for arg in "$@"; do
        echo -n "{$arg} "
    done
    echo
}

var1="Two bits"

# Print var1 as one string.
my_print "\$var1 = $var1"
# Output: {$var1 = Two bits}.

# "Double quoting is actually 'unquoting'". "\var1 =" is inside quotes, $var is outside
# of the quotes, and the "" is an empty string at the end.
#
# Therefore this gets interpreted as the two strings "\$var1 = Two" and "bits".
my_print "\$var1 = "$var1""
# Output: {$var1 = Two} {bits}
