A hopefully-simple bulk-renaming utility.
Its capabilities currently include dry-run, regex and (simply?) tweaked output.
The most basic usage is simply rena <folder>, which runs against a folder, renaming everything with the pattern of item_{:10>number}, where number is the item's number when being read.
The padding amount can be adjusted with --padding <number>, and the direction with --padding-direction <direction>, and the prefix with --prefix <prefix>.
It can also run in regex mode, by default as a filter if only --match <regex> is used. If --match-rename <pattern> is also used, it renames everything based on a pattern. The exact syntax is described in --help.
See -h or --help for all flags.
Currently only has the most basic execution mode covered, I hope to add more.
Let's say there's a directory named images with the following structure:
md
image.jpg
image3.jpg
12746uju21.jpg
17f29a002.jpg
After running rena images/, it will result in:
md
item_0000000000.jpg
item_0000000001.jpg
item_0000000002.jpg
item_0000000003.jpg
Let's say there's a directory named images with the following structure:
md
image.jpg
image3.mp4
12746uju21.jpg
17f29a002.jpg

ffe_image_breaker.webm

After running rena --match "\.[jpgn]+" images/, it will result in:
md
ffe_image_breaker.webm
image3.mp4
item_0000000000.jpg
item_0000000001.jpg
item_0000000002.png
item_0000000003.jpg
item_0000000004.jpg
Let's say there's a directory named Show with the following structure:
md
Show.S01E01.1080p.mkv
Show.S01E02.1080p.mkv
Show.S01E03.1080p.mkv
Show.S02E01.1080p.mkv
Show.S02E02.1080p.mkv
Show.S02E03.1080p.mkv
After running rena --match "Show\.S(\d+)E(\d+)\.1080p\.mkv" --match-rename "Show S${1} E${2} (1080p).mkv" Show/, it will result in:
Note: most shells will require escaping the $-sign
md
Show S01 E02 (1080p).mkv
Show S01 E03 (1080p).mkv
Show S02 E01 (1080p).mkv
Show S01 E01 (1080p).mkv
Show S02 E02 (1080p).mkv
Show S02 E03 (1080p).mkv
