       This program was written for Debian as a free replacement for the non-free rpl program by Joe Laffey.

       usage:  rpl  [-h]  [--version]  [--encoding  ENCODING]  [-E] [-i] [-m] [-w] [-b] [-q] [-v] [-s] [-e] [-F]
       [--files] [-x GLOB] [-R] [-p] [-f] [-d] OLD-TEXT NEW-TEXT [FILE ...]

       Search and replace text in files.

       Text matching the pattern OLD-TEXT is replaced by NEW-TEXT in each FILE. The pattern may  match  multiple
       lines.

       Filenames  may  include glob patterns (these must be quoted to avoid being interpreted by the shell), and
       in particular may use ‘**’ to match all files and zero or more directories and subdirectories. Tilde  and
       environment variable expansion is also performed.

   positionalarguments:
              OLD-TEXT NEW-TEXT FILE                  `-' or no FILE argument means standard input

   options:-h, --help
              show this help message and exit

       --version
              show program's version number and exit

       --encoding ENCODING
              specify character set encoding

       -E, --extended-regex
              use extended regular expression module `regex'

       -i, --ignore-case
              search case-insensitively

       -m, --match-case
              ignore  case  when  searching,  but  try  to match case of replacement to case of original, either
              capitalized, all upper-case, or mixed

       -w, --whole-words
              whole words (OLD-TEXT matches on word boundaries only)

       -b, --backup
              rename original FILE to FILE~ before replacing

       -q, --quiet
              quiet mode

       -v, --verbose
              verbose mode

       -s, --dry-run
              simulation mode

       -e, --escape
              expand escapes in OLD-TEXT and NEW-TEXT [deprecated]

       -F, --fixed-strings
              treat OLD-TEXT and NEW-TEXT as fixed strings, not regular expressions

       --files
              OLD-TEXT and NEW-TEXT are file names to read patterns from

       -x GLOB, --glob GLOB
              modify only files matching the given glob (may be given more than once)

       -R, --recursive
              search recursively

       -p, --prompt
              prompt before modifying each file

       -f, --force
              ignore errors when trying to preserve attributes

       -d, --keep-times
              keep the modification times on modified files

       Replace all occurrences of the word ‘F’ with ‘A’ in all files  with  extension  .txt  under  the  grades/
       directory:

              rpl -w F A 'grades/**/*.txt'
