Backslash Symbol

In the shell, the backslash symbol serves the following purposes:

Suppression of Interpolation

The backslash symbol is be used to prevent [interpolation] of [metacharacters] by the shell. By prefixing the dollar [symbol] with a backslash [metacharacter], we prevent interpolation from taking place: 

 price=300
 echo "Cost is $price dollars"   # Without the backslash $price is output as 300
 echo "Cost is \$price dollars"  # Interpolation of $price does not take place
