Re^4: shedding a bash wrapper and updating to Path::Tiny

Hello Datz_cozee75,

Here are a few comments.

Path::Tiny has a method for getting the absolute path of the current working directory, so path(".")->absolute; with Path::Tiny->cwd;
You do not need to quote the variables when you create a new path, so code like this path( "$current", "$to", "$ts" ) can be changed to code like this path( $current, $to, $ts )
You do not need to use stringify on a path before printing it, so code like this say "string abs from is $string_abs_from"; can be changed to use the variable that contains the Path::Tiny object like this say "string abs from is $abs_from";. Generally, Path::Tiny objects will stringify on their own when necessary. However, there may be times when you are passing a Path::Tiny object to another method (for example, a method from a different CPAN package) you may sometimes need to stringify the path first.
I like to use named variables in my foreach loops, so I made some changes to reflect this.
The Path::Tiny children method can be given an argument of a regular expression, where only children that match the regular expression are returned. This allowed me to simplify your code a bit.

Here is the modified code. Please note that this code is untested and I did this quickly, so it may need some small adjustments and there may be some typos. Please be sure that you have a backup of your data before running this code.
