Bash Script Properties File Using '.' in Variable Name

Question

I\'m new to bash scripting and have a question about using properties from a .properties file within a bash script.

I have seen a bash properties file that uses\'.\'

Answer 1

No can do. The bash manual says this about variable names:

name

A word consisting solely of letters, numbers, and underscores, and beginning with a letter or underscore. Names are used as shell variable and function names. Also referred to as an identifier.

Dots not allowed.
