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

dot is not allowed to be variable name. so you cannot just simply source the property file.

What you can do is:

"parse" the file, not source it. E.g. with perl, awk or grep to get the value of interesting property name, and assign it to your shell var.

if you do want to set a var with dot in its name, you can use env 'a.b.c=xyz' and get the a.b.c from env output.
