rename

A cli tool to rename files in bulk.

Why?

I don't like the perl-rename or the rename tool in linux. I could learn to get better at them but I don't want to. Anyway regex can get pretty gaudy and it's not intuitive to me to come with the right pattern on the fly in a timely manner. So I'm experimenting here with a simpler syntax: hello(n:int)->hi(n) which reads better and looks self-explanatory. But I don't rename files that often so maybe it doesn't matter.

Install (Unix)

export VER=$(wget -qO- https://github.com/Gnarus-G/rename/releases/latest | grep -oP 'v\d+\.\d+\.\d+' | tail -n 1);
curl -L https://github.com/Gnarus-G/rename/releases/download/$VER/rn-$OSTYPE.tar.gz -o rename.tar.gz
tar -xzvf rename.tar.gz rn
# Allow to able to run it from anywhere [Optional]
sudo mv rn /usr/local/bin

Usage

Grab a binary (linux or mac) in releases or run the install script above.

./rn simple --help

For example to replace file1, or file99 to 1renamed.txt or 99renamed.txt

Experimental MRP (Match Replace Protocol)

./rn simple "file(n:int)->(n)renamed.txt" file*

Regular Expression

./rn regex "file(\d+)" '${1}renamed.txt' file*

Demo

Performant (2x faster that perl-rename)

One might say, blazingly fast?

Note

The "simple" match and replace syntax is still in development. The happy path pretty much works, and the parser gives comprehensive error messages.
