Bash does not have a built-in function like other languages. However, a parameter expansion can be used to cut any string value. The three parts defined in parameter expansion are the primary string variable that has to be cut, starting position, and length of the cutting string. The first two are mandatory; the last one is optional. The starting position is counted from 0, and length must be counted from 1 of the main string.
