The two-option data type offers only two choices. In the above example, we have declared a few variables with different data types. If you create a FAT or NTFS partition, the Microsoft Basic Data type code will be applied. See String Type Storage Requirements for storage requirements for the SET type. Just like system variables, user variables can be referenced using the dollar sign: $ cat test3 #!/bin/bash A variable is nothing more than a pointer to the actual data. Isn't that awesome? "bash" ---> String Data Type; So, it’s totally ok to store different data types into the same array. It only understands integers. See Section 11.3.1, “String Data Type Syntax” for SET type syntax and length limits. Since bash does not discriminate string from a number, an array can contain a mix of strings and numbers.
