===============================================================================
cdll is a replacement for cd and incorporates similar functionality to
the bash pushd and popd commands but is independent of them.
This version of cdll has been tested on Linux using Bash. It will work
on most Linux versions but will probably not work on other shells without
modification.
Introduction
============
cdll allows easy moving about between directories. When changing to a new
directory the current one is automatically put onto a stack. By default
50 entries are kept, but this is configurable. Special directories can be
kept for easy access - by default up to 10, but this is configurable. The
most recent stack entries and the special entries can be easily viewed.
The directory stack and special entries can be saved to, and loaded from,
a file. This allows them to be set up on login, saved before logging out
or changed when moving project to project.
In addition, cdll provides a flexible command prompt facility that allows,
for example, a directory name in colour that is truncated from the left
if it gets too long.
Setting up cdll
===============
Copy cdll to either your local home directory or a central directory
such as /usr/bin (this will require root access).
Copy the file cdfile to your home directory. It will require read and
write access. This a default file that contains a directory stack and
special entries.
To replace the cd command you must add commands to your login script.
The login script is one or more of:
/etc/profile
~/.bash_profile
~/.bash_login
~/.profile
~/.bashrc
/etc/bash.bashrc.local
To setup your login, ~/.bashrc is recommended, for global (and root) setup
