Great Job!

Putting “mdump” or its source code in ~/.bash_logout did not work.

So after little testing adding mdump to the m1-9 commands solves it.

Enjoy.

I like the simplicity of it – with the numbers from 1-9.

INSTALL instructions:
- put into ~/bin/bookmarks or sth.
- source it from ~/.bashrc – add “. ~/bin/bookmarks”
USAGE:
- use m1-9, g1-9 and lma.
- sing/hum some nice melody

#!/bin/bash
# Bash Directory Bookmarks
alias mdump=’alias|grep -e “alias g[0-9]“|grep -v “alias m” > ~/.bookmarks’
alias lma=’alias | grep -e “alias g[0-9]“|grep -v “alias m”|sed “s/alias //”‘
alias m1=’alias g1=”cd `pwd`”; mdump’
alias m2=’alias g2=”cd `pwd`”; mdump’
alias m3=’alias g3=”cd `pwd`”; mdump’
alias m4=’alias g4=”cd `pwd`”; mdump’
alias m5=’alias g5=”cd `pwd`”; mdump’
alias m6=’alias g6=”cd `pwd`”; mdump’
alias m7=’alias g7=”cd `pwd`”; mdump’
alias m8=’alias g8=”cd `pwd`”; mdump’
alias m9=’alias g9=”cd `pwd`”; mdump’
touch ~/.bookmarks
source ~/.bookmarks

In zsh alias does not print alias g1 but just g1. Ugly hack to get it to print this (i am new to grep, awk, zsh) so please fix the ugly ugly mdump and lma lines!

#ZSH Directory Bookmarks
alias m1=’alias g1=”cd `pwd`”‘
alias m2=’alias g2=”cd `pwd`”‘
alias m3=’alias g3=”cd `pwd`”‘
alias m4=’alias g4=”cd `pwd`”‘
alias m5=’alias g5=”cd `pwd`”‘
alias m6=’alias g6=”cd `pwd`”‘
alias m7=’alias g7=”cd `pwd`”‘
alias m8=’alias g8=”cd `pwd`”‘
alias m9=’alias g9=”cd `pwd`”‘

alias mdump=’alias | grep -e “g[0-9]=” | grep -v “m[0-9]” | awk ‘\”{ print “alias ” $1 ” ” $2 }’\” | cat > ~/.bookmarks’

alias lma=’alias | grep -e “g[0-9]=” | grep -v “m[0-9]” | awk ‘\”{ print “alias ” $1 ” ” $2 }’\”’

touch ~/.bookmarks
source ~/.bookmarks

Karthick,
Amazing ! This is way better than my implementation. The snippet below adds tab completion to your script.


# enable custom tab completion

shopt -s progcomp
# jump to bookmark

function g {

   source ~/.sdirs

   cd $(eval $(echo echo $(echo \$DIR_$1)))

}
# list bookmarks without dirname

function _l {

   source ~/.sdirs

   env | grep "^DIR_" | cut -c5- | grep "^.*=" | cut -f1 -d "="

}
# completion command for g

function _gcomp {

    local curw

    COMPREPLY=()

    curw=${COMP_WORDS[COMP_CWORD]}

    COMPREPLY=($(compgen -W '`_l`' -- $curw))

    return 0

}
# bind completion command for g to _gcomp

complete -F _gcomp g
# Usage: g [TAB]

Btw, it is also possible to use TAB completion on bookmark names using compgen/complete in bash.. so doing something like:
$ g my
should complete to
$ g mybookmarkname

I did the following to give descriptive bookmark names:

function s { cat ~/.sdirs | grep -v "export DIR_$1=" > ~/.sdirs1 mv ~/.sdirs1 ~/.sdirs echo "export DIR_$1=$PWD" >> ~/.sdirs }


function g {

   source ~/.sdirs

   cd $(eval $(echo echo $(echo \$DIR_$1)))

}

function l { source ~/.sdirs env | grep "^DIR_" | cut -c5- | grep "^.*=" }

Mnemonics:
s – Save directory (argument is a shorthand bookmark name)
g – Go to directory
l – List saved directories

Usage:
$ cd /foo/bar/some/dir
$ s mybookmarkname

…
In an other shell:
$ l
mybookmarkname=/foo/bar/some/dir
$ g mybookmarkname
should take you to /foo/bar/some/dir

Obviously you’ll use far less characters than the 14 used in “mybookmarkname”..

Incidentally, it is also ok to leave the bookmark name..
$ cd /foo/bar/some/dir
$ s

…
In an other shell:
$ l
=/foo/bar/some/dir
$ g
should take you to /foo/bar/some/dir

ubersoldat, yes I have a similar alias “lma” that is used for listing the bookmarks.

Very nice! Think I will use this today!

You could also find useful listing your bookmarks:

alias favs=’alias|grep -e “alias g[0-9]“|grep -v “alias m”

Good idea. I just added it to my bash_logout

I created a similar .bat script for windows.
Mine is d.bat

To add an alias to the current directory you type ‘d ‘.
And then to go to that directory it is the same command.

An additional feature I have is it adds each alias as an environment variable prefixed with ‘d-’. You can then use those as parameters for other commands.

eg.
C:\Windows> d win
d-win=C:\Windows
C:\Windows> cd /d F:\test
F:\test> d test
d-test=F:\test
F:\test> d win
C:\Windows> copy *.* %d-test%
