not just one directory. Also use shorter versions of the `tar` parameters, since we were using a mixture of the short and long ones among `archive` and `unarchive`. About not using `$` inside `(( ))`, this is what the the section ARITHMETIC EVALUATION in zshmisc(1) says: > Named parameters and subscripted arrays can be referenced by name > within an arithmetic expression without using the parameter expansion > syntax. And according to http://www.bash2zsh.com/zsh_refcard/refcard.pdf: > `var` (does not require `$` in front unless some substitution e.g. > `${#var}` is needed, `$` is error if `var` is to be modified) Closes #308
