configuration file

A configuration file .spdrc is created on the first program execution.

The configuration file defines the regexp to search after cleaning lines.

You can define new formats to detect and extract links.

usage

The program takes url or file as the first parameter.

usage: scan-public-directory url [-h] [--max-depth LEVELS]
                                 [--min-depth LEVELS] [--min-size SIZE]
                                 [--max-size SIZE] [--accept LIST]
                                 [--reject LIST] [--verbose]

                                 [--exec COMMAND]

optional arguments:
  -h, --help          show this help message and exit

                      element of the list, it will be treated as a pattern,
                      rather than a suffix
  --reject LIST       Reject the files with the specified file name suffixes
                      or patterns (comma separated list). If any of the
                      wildcard characters, *, ?, [ or ], appear in an element

  --before DATETIME   Reject the files with date/time after the specified
                      datetime (YYYY-MM-DD hh:mm)
  --lines LINES       Select specified lines matching all filters (N, N-, N-M,
                      -M)
  --banner            Display banner
  --print FORMAT      Print the given string replacing patterns {index} {date}
                      {size} {url} by their respective values
  --exec COMMAND      Execute the given shell command (ex: echo "#{index}
                      {date} // {size} // {url}"). If command starts with : it
                      is considered as an alias

examples of use

$ ./scan-public-directory url http://example.com/images/ | tee photo.txt
2009-02-01 11:13|2.4M|http://example.com/images/02-09.jpg
2010-11-03 10:36|3.4M|http://example.com/images/021110.jpg
2007-03-01 08:21|4.1M|http://example.com/images/03-07.jpg

$ ./scan-public-directory file photo.txt --accept '*-0*' --before '2015-12-25 19:34' --max-size '3M'
2009-02-01 11:13|2.4M|http://example.com/images/02-09.jpg

If necessary, after filtering, you can call a shell command (see the --exec option in the usage)
