If you're just switching between two directories, you can use cd - to go back and forth.

There is a shell variable CDPATH in bash and ksh and cdpath in zsh:

CDPATH    The search path for the cd command. This is a colon-separated

          list of directories in which the shell looks for destination

          directories specified by the cd command.

So you can set in your ~/.bashrc:

export CDPATH=/Project/Warnest:~/Dropbox/Projects/ds

Then cd docs and cd test will take you to the first found such directory. (I mean, even if a directory with the same name will exist in the current directory, CDPATH will still be consulted. If CDPATH will contain more directories having subdirectories with the given name, the first one will be used.)

Something else you might try is a tool called autojump. It keeps a database of calls to it's alias (j by default) and attempts to make intelligent decisions about where you want to go. For example if you frequently type:

j ~/Pictures

You can use the following to get there in a pinch:

j Pic

It is available of Debian and Ubuntu, and included on a per-user basis in ~/.bashrc or ~/.zshrc by default.

If it's a small number of directories, you can use pushd to rotate between them:

# starting point

$ pwd

/Project/Warnest/docs

# add second dir and change to it

$ pushd ~/Dropbox/Projects/ds/test

~/Dropbox/Projects/ds/test /Project/Warnest/docs

# prove we're in the right place

$ pwd

~/Dropbox/Projects/ds/test

# swap directories

$ pushd

/Project/Warnest/docs ~/Dropbox/Projects/ds/test

unlike cd -, you can use this with more than two directories

Following up on Noach's suggestion, I'm now using this:

function pd()

{

    if [[ $# -ge 1 ]];

    then

        choice="$1"

    else

        dirs -v

        echo -n "? "

        read choice

    fi

    if [[ -n $choice ]];

    then

        declare -i cnum="$choice"

        if [[ $cnum != $choice ]];

        then #choice is not numeric

            choice=$(dirs -v | grep $choice | tail -1 | awk '{print $1}')

            cnum="$choice"

            if [[ -z $choice || $cnum != $choice ]];

            then

                echo "$choice not found"

                return

            fi

        fi

        choice="+$choice"

    fi

    pushd $choice

}

example usage:

# same as pushd +1

$ pd 1



# show a prompt, choose by number

$ pd

 0 ~/Dropbox/Projects/ds/test

 1 /Project/Warnest/docs

 2 /tmp

? 2

/tmp ~/Dropbox/Projects/ds/test /Project/Warnest/docs



# or choose by substring match

$ pd

 0 /tmp

 1 ~/Dropbox/Projects/ds/test

 2 /Project/Warnest/docs

? doc

/Project/Warnest/docs /tmp ~/Dropbox/Projects/ds/test



# substring without prompt

$ pd test

~/Dropbox/Projects/ds/test /Project/Warnest/docs /tmp

etc. Obviously this is just for rotating through the stack and doesn't handle adding new paths - maybe I should rename it.

I use alias in bashrc to do those cds.

such as:

alias wdoc='cd ~/Project/Warnest/docs'

alias dstest='cd ~/Dropbox/Projects/ds/test'

I found a script (typically called acd_funch.sh) that solved this issue for me. With this you can type cd -- to see the last 10 directories that you've used. It'll look something like this:

0  ~/Documents/onedir

1  ~/Music/anotherdir

2  ~/Music/thirddir

3  ~/etc/etc

To go to ~/Music/thirddir just type cd -2

References

• scripts/acd_func.sh


• SkyRocknRoll / acd_func.sh

NOTE: This script was originally published in a linux gazette article which is available here: acd_func.sh -- extends bash's CD to keep, display and access history of visited directory names.

Try the cdable_vars shell option in bash. You switch it on with shopt -s cdable_vars.

Then you need to set your variables export dir1=/some/path. and finally cd dir1, etc.
You can then put it in your ~/.bashrc to make it stick.

Use "pushd -n" (assuming you use bash).

Add to your ~/.bashrc:

pushd -n /Project/Warnest/docs/

pushd -n ~/Dropbox/Projects/ds/test/

then,

cd ~ is your home,

cd ~1 is ~/Dropbox/Projects/ds/test/

cd ~2 is /Project/Warnest/docs/

You can use ~1,~2 etc in exactly the same way as ~.

There are a lot of good suggestions here. Which to use would depend on whether you have a small fixed list of directories you switch among, or whether you are looking for a more generic solution.

If it's a small fixed list, setting up simple aliases (as Felix Yan suggested) would be easiest to use.

If you're looking for a more generalized solution (i.e. many different directories, changing over time), I'd use pushd and popd (as Useless suggested). I personally find the default pushd/popd to be hard to use, especially as you start switching among many folders; however I wrote a few tweaks that make it much easier for me. Add the following to your bashrc:

alias dirs='dirs -v'

pd () 

{ 

    if [ "$1" ]; then

        pushd "${1/#[0-9]*/+$1}";

    else

        pushd;

    fi > /dev/null

}

• Use pd (as a shorter form of pushd) to jump to a new folder, remembering where you were.


• Use dirs to see the list of saved directories.


• Use pd 3 to jump to directory number 3.

Example Usage:

$ PS1='w$ '   ## just for demo purposes

~$ pd ~/Documents/data

~/Documents/data$ pd ../spec

~/Documents/spec$ pd ~/Dropbox/Public/

~/Dropbox/Public$ pd /tmp

/tmp$ pd /etc/defaults/

/etc/defaults$ dirs

 0  /etc/defaults

 1  /tmp

 2  ~/Dropbox/Public

 3  ~/Documents/spec

 4  ~/Documents/data

 5  ~

/etc/defaults$ pd 2

~/Dropbox/Public$ dirs

 0  ~/Dropbox/Public

 1  ~/Documents/spec

 2  ~/Documents/data

 3  ~

 4  /etc/defaults

 5  /tmp

~/Dropbox/Public$ pd 4

/etc/defaults$ dirs

 0  /etc/defaults

 1  /tmp

 2  ~/Dropbox/Public

 3  ~/Documents/spec

 4  ~/Documents/data

 5  ~

/etc/defaults$ pd 3

~/Documents/spec$ popd

~/Documents/data ~ /etc/defaults /tmp ~/Dropbox/Public

~/Documents/data$ 

The following appeared to work on the one case I tested it on, and you can just drop your directory names as symlinks in ~/Bookmarks:

mkdir "$HOME/Bookmarks"

ln -s /tmp "$HOME/Bookmarks/testdir"



function ccd() { cd $(readlink "$HOME/Bookmarks/$1") ; }



ccd testdir && echo $PWD

# gives /tmp

You could do worse than try j2.

From the README:

Spend a lot of time cd-ing around a complex directory tree?

j keeps track of where you’ve been and how much time you spend there, and provides a convenient way to jump to the directories you actually use.

I use it extensively & recommend it.

I'd advice using zsh, that shell as very good TAB completion for directories, files, and even options for most cli programs.

I've been using that shell for years now, and I'd miss the functionality if it was gone.
Scripting the zsh is a lot of fun, too, with a large number of one-liners that can help you every day.

In my experience, the greatest speedup in navigating in a shell is to use its history search functionality. In Bash you can search backwards in your history of commands by pressing Ctrl+R and type in some pattern. That pattern is then matched against previous entries in your history -- may it be cd commands or other operations -- and suggestions are made as you type. Simply hit enter to run the suggested command again. This is called reverse-search-history in Bash and I love it. It saves me a lot of keystrokes and spares my internal memory.

It's a good thing because you only have to remember some smaller part of a command, like Drop or Wa to distinguish between the two history entries cd ~/Dropbox/Projects/ds/test/ and cd /Project/Warnest/docs/.

I also use these aliases (add them to ~/.bashrc):

alias ..='cd ..'

alias ...='cd ../..'

alias ....='cd ../../..'

alias .....='cd ../../../..'

It's much quicker to go to the upper directory with them (yet it only solves half of the navigation).

if you're using zsh:

• 
  

  you don't have to type cd, just type directory path (/foo/bar/baz<Enter> equals to cd /foo/bar/baz<Enter>)

  
  
  

  requires auto_cd option to be set

  
  


• you can expand abbreviated paths with Tab key (/u/sh/pi<Tab> expands to /usr/share/pixmaps; works for file names as well)

There is a rather nice tool for quick directory changes:

xd - eXtra fast Directory changer
http://xd-home.sourceforge.net/xdman.html

a bit awkward is that you need to map it in bash profile or similar as it only outputs the directory

# function to do `cd` using `xd`

# -g turns generalized directory search command processing on

# which improves the whole thing a bit

f() 

{

        cd `/usr/bin/xd -g $*`

}

you can do things like:

# change to /var/log/a* (gives you a list to choose from)    

f vla

# to skip the list and go directly to /var/log/apache2

f vlapach

You never ever should type full path in shell anyway. You always can use:

soffice /P*/W*/*/mydoc*

instead of

soffice /Project/Warnest/docs/mydoc.odt

There's also OLDPWD, an environment variable which, according to IEEE 1003.1 (POSIX), should be updated with the previous working directory each time cd changes the working directory (for the curious ones, line 80244 of page 2506 of IEEE 1003.1-2008).

There is also a "wcd" app created specifically for this (also ported to cygwin, since I am on that). You can create shortcuts, bookmarks of dirs with it. Also supports wild cards. Reading the man page & docs in /usr/share/wcd should help a lot.

http://manpages.ubuntu.com/manpages/hardy/man7/wcd.7.html

cdargs is the most efficient tool for bookmarking a directory: http://www.youtube.com/watch?v=uWB2FIQlzZg

Try fastcd (https://github.com/frazenshtein/fastcd)
It sets hook that records visited directories from bash. And sets script as "j" alias, that shows you the last visited directories, with the ability to quickly cd (start typing to filter directories).
Modification of .bashrc is required to make the "j" alias.

Getting tool

cd ~; mkdir Soft; cd Soft

git clone https://github.com/frazenshtein/fastcd

Install required modules

pip install --user urwid

Source the set.sh file into your bashrc

echo -e "nsource /home/$USER/Soft/fastcd/set.shn" >> ~/.bashrc

And update bashrc

source ~/.bashrc

Then just type "j" in console

I had the same question, and first found this answer. I installed the utility z (https://github.com/rupa/z).

This is exactly what you look for, because z learns from your cd commands, and keeps track of the directories according to the frecency principle (frequent & recent). So after you do both cd commands once, you can do somtehing like:

z docs

z ds

to jump to /Project/Warnest/docs/ and ~/Dropbox/Projects/ds/test/ respectively. The arguments to z are regexes, so you don't even need to type a full folder name.

Update (2016): I now use FASD for this, which allows fuzzy search based on your latest directories.

I've created a tool for this, in Ruby. It allows you to use YAML files to declare your projects.

I've wrote a little article about it here:
http://jrnv.nl/switching-projects-terminal-quickly/

I've also posted the source on GitHub:
https://github.com/jeroenvisser101/project-switcher

I've been using my own utility cdhist to manage this for many years. It aliases your cd command and automatically keeps a directory stack.

You can use export to assign your directory paths to variables and then reference them.

export dir1=/Project/Warnest/docs/

export dir2= ~/Dropbox/Projects/ds/test/

cd $dir1

cd $dir2

Some suggestions here:

Most direct idea, I will add alias in the .profile file

vi ~/.profile

alias dir1='cd /myhome/onedir'

alias dir2='cd /jimmy/anotherdir'

Then use $ dir1 or dir2, can cd

If you are always switching in two dirs only. using cd - will switch between them.

The solution I use for this situation is screen. Start screen and create a window for each directory with C-a c and navigate there. Change between windows/directories with C-a n or C-a p. Name the windows with C-a A. Then you can pop up a list of your windows with C-a " and navigate using the window number or name. Since it is screen, you can detach from the session saving your work space and re-attach later with the same set up.

It seems that what you need is basically a project file for your workflow. With directories that belong to your activity, like in a programming IDE. Try Zsh Navigation Tools and the tool n-cd there. It will allow you to navigate across last visited folders and also define a Hotlist with directories of your choice:

n-cd can be bound to a key combination with:

zle -N znt-cd-widget

bindkey "^T" znt-cd-widget

TL;DR

1. Use an Fish for interactive shell that empower you immediately (fish>zsh>bash).


2. Use POSIX/Bash for scripting that is the most widely supported syntax (POSIX>Bash>Zsh>Fish).

Shells

Having tested different shells here is my feedback (in order of testing/adoption):

• 
  Bash:
  
  
  
  
  • auto-completion: basic ;
  
  
  • path expansion: no ;
  
  
  • scripting: excellent.
  
  
  
  


• 
  Zsh+oh-my-zsh:
  
  
  
  
  • auto-completion: good (cycling through);
  
  
  • path expansion: yes (cd /e/x1 → cd /etc/X11/) ;
  
  
  • scripting: good.
  
  
  
  


• 
  Fish+oh-my-fish (current) is the best out of the box:
  
  
  
  
  • auto-completion: native and supported options;
  
  
  • path expansion: yes ;
  
  
  • scripting: too much difference from POSIX-compatible.
  
  
  
  

Use meaningful aliases

Every shell can be expanded using function and alias, here are the ones I use related to your issue (POSIX-compatible):

back () {  # go to previous visited directory

        cd - || exit

}



up () {  # go to parent directory

        cd ..|| exit

}

There are basic, but really meaningful so easy to remember and autocomplete.

Know your shell

Configure CDPATH to add your most used directories (e.g. ~/projects/, /etc/init.d/) so you can quickly jump to them.

See manatwork answer for mroe details on CDPATH.

anc is a cmd line tool (short for anchor), that keeps bookmarks of directories. (so far only tested with bash)

In your case:

anc a /Project/Warnest/docs/ ~/Dropbox/Projects/ds/test/

this adds both directories to the anchor(think bookmarks) list

now if you want to jump to /Project/Warnest/docs/ from anywhere
on your system type:

anc Warn

and if you want to jump to ~/Dropbox/Projects/ds/test/ type:

anc ds test

Apart from matching text against the bookmarked paths anc has many other
convenient ways for jumping around directories.

anc i

starts the interactive mode, that lists all bookmarks by number,
so all you have to type is the number

If you type:

anc Pro[TAB]

a list matching all bookmarks (in your case both bookmarks) gets shown and you can select from it using your arrow keys, this is a very quick and intuitive way.

Get anc at the project's github page:
https://github.com/tobimensch/anc

There's also a README with example usage.

Full disclosure: I'm the author of this script. I hope some people will find it useful.
