filename_cleaner

Quickly rename list of files with extension and replace any special characters with with any given string.

Currently any string that are not one of letters (a..z, A..Z), numbers (0..9), _ (underscore), - (dash), and ' ' spaces string are first squeezed into one string and then replaced by any given string/char [default to . (a single dot)].

Optionally, you could also

• capitalized each word in the output
• make each word in output lower case
• use more than one character as the separator string if you prefer

cd ~/projects/files
filename_cleaner --base-dir . --exts java rb --recursive --sep-char _

To make your change permanent:

cd ~/projects/files
filename_cleaner --base-dir . --exts java rb --recursive --sep-char _ --commit

Us as library in your project

Add this line to your application's Gemfile:

gem 'filename_cleaner'

And then execute:

$bundle

Example Usage:

• Use the default separator string '.'

require 'filename_cleaner'
# Treat the input as having extension (e.g. at least one dot within the input)
new_name = FilenameCleaner.sanitize('some b@d fil$name.txt', '_', true)
puts new_name # => 'some_b_d_fil_name.txt'

# Treat the input as having no extension (ignore the meaning of within the input)
new_name = FilenameCleaner.sanitize('some b@d fil$name.txt', '_', false)
puts new_name # => 'some_b_d_fil_name_txt'
