Usage

$ pdf-renamer [dry] glob-pattern search-regex name-pattern

    dry             If specified, writes output to console
                    only and does not actually rename files

                    source files to rename

    search-regex    Regular expression identifying text
                    content to search for and extract for
                    the new file name

                    substitutions for regex captures. Note
                    that all illegal file characgters are

Examples:

    Explanation

    dry
            Will do a dry run, output to console only

     ~/docs/uploads/*.pdf

             Will look for all files with a .pdf extension
             in the ~/docs/uploads directory

    "Invoiced (\d\d.\d\d).(\d\d\d\d)"

             Will look for the text Invoiced followed by a
             date such as 03/10/2020 and capture the date
             for reuse in the new file name

    invoice-$1.pdf

             Files renamed with the capture with year
             first, such as invoice-2020-03-10.pdf.
