Utilities to let you easily reach frequently visited but deeply nested directories.

# Utilities for quickly accessing frequently used directories in bash.

# Usage:
#   $ cd /path/to/project/src/
#   $ mark code     # Will create a new shortcut.
#                   # Becomes interactive if a shortcut already exists
#                   # m is an alias for mark. You can also `m code`
#
#   $ code          # From now on, running this anywhere in the shell
#                   # will put you in /path/to/project/src/code
#
#   $ unmark code   # Will remove the symlink and is interactive
#                   # u is an alias for unmark. You can also `u code`

SHELLMARKSDIR="$HOME/.shellmarks"
mkdir -p $SHELLMARKSDIR
function mark_alias { alias $(basename $1)="cd -P $1"; }

function mark { # Mark a directory
    symlink=$SHELLMARKSDIR/$1
    ln -ivns "$(pwd)" $symlink && mark_alias $symlink
}
alias m=mark

function unmark { # Remove a mark
    symlink=$SHELLMARKSDIR/$1
    rm -iv $symlink
    if [ ! -f $symlink ]; then
        unalias $1
    fi
}
alias u=unmark

function shellmarks { # List all existing marks
    LINK_COLOR=$'\e[1;35m'
    RESET_COLOR=$'\e[0m'
    for symlink in $SHELLMARKSDIR/*; do
        test -L $symlink && echo "${LINK_COLOR}    $(basename $symlink) ${RESET_COLOR} -> $(readlink $symlink)"
    done
}

for symlink in $SHELLMARKSDIR/*; do # load all existing symlinks as aliases
    mark_alias $symlink
    test -L $symlink && ( test -e $(readlink $symlink) || rm $symlink ) # remove symlinks if source does not exist
done

Awesome!

There's a utility called autojump which has completely replaced cd for me:

https://github.com/joelthelion/autojump

No need to mark folders. As soon as you've visited one it's in the database and can be jumped to (including tab completion from anywhere).

There is also a utility called z which replaced both cd and autojump for me:

https://github.com/rupa/z

DESCRIPTION
       Tracks your most used directories, based on 'frecency'.

       After  a  short  learning  phase, z will take you to the most 'frecent'
       directory that matches ALL of the regexes given on the command line.

There's a utility called fasd that provides a superset of both z and autojump functionality:
