Hi Everyone,

I am working on a bash script, and currently looking at examples. I came across something I'm not sure what it means: if (( $? )); , the double quotes and the $? is what I don't get. In the script there is no variable set for ? so kinda lost.

Possible info: Simply enclose the particular arithmetic expression between a "$((" and a "))", and bash will evaluate the expression.

And also anyone have recommendation of a good bash scripting book.

Learning the bash Shell, 2nd Edition?

Thanks,
