  Usage
  $ renamer <options> <files>
 
  -f, --find <string>      The find string, or regular expression when --regex is set. If not set, the whole filename will be replaced.
  -r, --replace <string>   The replace string. With --regex set, --replace can reference parenthesised substrings from --find with $1, $2, $3
                           etc. If omitted, defaults to a blank string. The special token '{{index}}' will insert an incrementing number per
                           file processed.
  -e, --regex              When set, --find is intepreted as a regular expression.
  -d, --dry-run            Used for test runs. Set this to do everything but rename the file.
  -i, --insensitive        Enable case-insensitive finds.
  -v, --verbose            Use to print additional information.
  -h, --help               Print usage instructions.

For more information on Regular Expressions, see this useful guide.

Don't forget to test your rename first using --dry-run!

Renamer comes with globbing support built in (provided by node-glob), enabling recursive operations. To recurse, use the ** wildcard where a directory name would appear to apply the meaning "any directory, including this one".

For example, this command operates on all js files in the current directory:

$ renamer --find this --replace that '*.js'

this command operates on all js files, recursively:

$ renamer --find this --replace that '**/*.js'

this command operates on all js files from the lib directory downward:

$ renamer --find this --replace that 'lib/**/*.js'

Bash users without globstar will need to enclose the glob expression in quotes to prevent native file expansion, i.e. '**/*.js'
