filerenamer: rename files and directories, optionally recursively.
version 0.0.2 : 09 April 2025
Golang program for renaming files and directories, optionally recursively.
All characters match the negative regexp [^A-Za-z0-9_.] are each
replaced with the _ underbar character. Leading, trailing and
sequential underbar characters in the base directory or filename are
removed. Remaining characters, including those in filename extensions
are lower-cased.
Usage:
frn Path
Recursively rename the file, directory or the directory and all files
under it (by providing a directory ending with a "/") provided by Path.
All non-word, . and _ characters will be replaced by "_" and the names
lowercased. If in doubt run in dryrun mode.
Application Options:
-v, --verbose verbose: record changes
-d, --dryrun dry-run mode: no changes will be made
Help Options:
-h, --help Show this help message
Arguments:
DirOrFilePath: directory path to process
