Program to provide a bash cd history directory stack

Project description

BASH SHELL CD HISTORY

cdhist is a utility which provides a bash shell cd history directory stack. A bash cd alias calls a python helper script to intercept your normal shell cd command and maintain a stack of directories you previously visited which can be listed and quickly jumped to by numeric index.

The latest version and documentation is available at http://github.com/bulletmark/cdhist.

USAGE

Add "somepath" to your directory stack and cd there:

cd somepath

List the current stack and its indices:

cd -l

Change dir to stack index "n":

cd -n

Search back through stack for "string" and cd there:

cd -/string

List the stack and its indices then immediately prompt for dir to select:

cd --

You can also type /string at the above prompt to search.

Show this help:

cd -h|?

All other arguments are passed on to the normal cd command.

INSTALLATION

Arch users can install cdhist from the AUR and skip to the next section.

Ensure python3-pip is installed. Bash and python 3.4 or later are required.

Note cdhist is on PyPI so you can just type sudo pip3 install cdhist. Or do the following:

git clone http://github.com/bulletmark/cdhist
cd cdhist
sudo pip3 install .

CONFIGURATION

Each user who wants to use the cdhist facility should source the cdhist.bashrc file into their bashrc, i.e in ~/.bashrc just add the following lines:

for _d in /usr/share /usr/local/share; do
    _f="$_d/cdhist/cdhist.bashrc"
    if [[ -r $_f ]]; then
	source $_f
	break
    fi
done

Then log out and back in again.

ALTERNATIVE COMMAND NAME

Some people may prefer not to alias their system cd command to this utility and just use an alternative unique command name. To do this, set CDHISTCOMMAND to your preferred name before you invoke the cdhist.bashrc script in your ~/.bashrc. E.g, to use the command name xd rather than cd add the following export after the if test and before the source line in the above.

export CDHISTCOMMAND=xd

Log out/in, and then just type xd /tmp to change dir, xd -- to see and select dirs, etc.

UPGRADE

cd cdhist  # Source dir, as above
git pull
sudo pip3 install -U .

REMOVAL

sudo pip3 uninstall cdhist
