What Are Shell Script Variables?

A variable in a shellscript is a means of referencing a numeric or character value. And unlike formal programming languages, a shell script doesn't require you to declare a type for your variables.

mkdir `date +%b%y`
(creates a directory Jul02)
mkdir `date +%b%Y`
(creates a directory Jul2002)
mkdir `date +%m%y`
(creates a directory 0702)
mkdir `date +%m%Y`
(creates a directory 072002)

mkdir `date +%b%y`

(creates a directory Jul02)

mkdir `date +%b%Y`

(creates a directory Jul2002)

mkdir `date +%m%y`

(creates a directory 0702)

mkdir `date +%m%Y`

(creates a directory 072002)
