A file-rename tool inspired by Perl's File::Rename.
If you have zef you can
- clone this repo
cd to it
zef install .
The distribution only provides the
rrnm binary. In general:
rrnm --help to see information on the possible command-line switches / options.
The first positional argument should be a substitution or transliteration operator, as documented under
Raku's substitution-operators doc section.
The positional arguments following that should be the files you want to move / copy / whatever (see the examples below).
The regex syntax is whatever
Raku will recognize.
Some usage examples follow, all of which are to be run in a terminal where you have access to
rrnm 's/^a/b/' <DIRECTORY>/a*
will rename every file / directory of the form
On the other hand,
rrnm -c='cp' 's/^a/b/' <DIRECTORY>/a*
will take every file of the form
<DIRECTORY>/a<BLAH> and copy it to
<DIRECTORY>/b<BLAH>. It will complain aboit not being able to copy directories among those (because the cp command behaves this way), but you can fix that with
rrnm -c='cp -r' 's/^a/b/' <DIRECTORY>/a*
You can even do the following in a
git repo, to effect a regex-based git-mv:
rrnm -c='git mv' 's/^(\d)/0$0/' [0-9]*
or equivalently, using lookahead assertions,
rrnm -c='git mv' 's/^<?before \d>/0/' [0-9]*
That will perform a
git mv on every file whose name starts with a digit, prepending a
0 (if you wanted to do this for some reason).
--dry option just shows you the command that would be run. So in a git repo that contains files
2.txt (and nothing else starting with a digit),
rrnm -c='git mv' 's/^(\d)/0$0/' [0-9]* --dry
would simply show you
git mv 1.txt ./01.txt
git mv 2.txt ./02.txt
in the terminal.
I use this all the time: first run what you think will work with
--dry, then recall the last command and remove the
