NAME

cdprev-backend - Change to the "previous" or "next" (sibling) directory

VERSION

This document describes version 0.010 of cdprev-backend (from Perl distribution App-CdUtils), released on 2025-09-23.

SYNOPSIS

To use in shell:

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

% pwd
/some/path

% ls
four/   one/   three/   two/

% cd four

% cdnext
% pwd
/some/path/one

% cdnext -n2
% pwd
/some/path/two

% cdprev -n3
% pwd
/some/path/four

DESCRIPTION

cdprev and cdnext are commands to change to "previous" and "next" sibling directories, respectively. By default, asciibetical ordering is used. You can change the ordering by setting the "CDPREVNEXT_SORT_FILES_OPTS" options, as sort-files utility is used to sort the directories.

OPTIONS

--num=i, -n

Integer. Default 1.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

complete -C cdprev-backend cdprev-backend

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.

tcsh

To activate tcsh completion for this script, put:

complete cdprev-backend 'p/*/`cdprev-backend`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.

ENVIRONMENT

CDPREVNEXT_SORT_FILES_OPTS

String. Options to pass to sort-files. Default: --by-field name.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
