NAME

cdpart-backend - Change directory part

VERSION

This document describes version 0.002 of cdpart-backend (from Perl distribution App-CdUtils), released on 2016-09-29.

SYNOPSIS

To use in shell:

% cdpart() { cd `cdpart-backend "$1"`; }

% cd /media/mv/en/c/celine-dion
% cdpart fr; # /media/mv/fr/c/celine-dion

DESCRIPTION

cdpart will try to substitute a directory element with specified argument, starting from the deepest. cdpart is useful if you have some branches with identical structures and you want to move to another branch quickly.

Suppose we have this directory structure:

media/
  mv/
    en/
      a/
      b/
      c/
        carly-rae-japsen/
        celine-dion/
        charlie-puth/
        ...
      ...
    fr/
      a/
      b/
      c/
        celine-dion/
        christophe-willem/
        ...
    de/
    ...
  music/
    en/
      a/
      b/
      c/
        celine-dion/
        ...
    fr/
      a/
      b/
      c/
        celine-dion/
        ...
      ...
    ...
 ...

You can see that the directories mv and music have the same structure: the first subdirectory level is language code (en, fr, ...), the second level is the first letter of artist's name (a, b, c, ...) and the third level is the name of the artist.

Suppose you are now in directory:

/media/mv/en/c/celine-dion

and you want to see Céline's French music videos (/media/mv/fr/c/celine-dion). If you use cd, the command will be:

% cd ../../fr/c/celine-dion

which is too much to type because you are retyping the substructure. With cdpart you just have to type:

% cdpart fr

What cdpart will do is try the following directories in order:

/media/mv/en/c/fr
/media/mv/en/fr/celine-dion
/media/mv/fr/c/celine-dion

The third succeeds so it goes there. If no match is found until the topmost directory, cdpart will not change directory.

Another example:

% cdpart music

will eventually change the directory to /media/music/fr/c/celine-dion.
