awk '{print $1}' ~/.bash_history | sort | uniq -c | sort -n | tail -5
The command 'cd' always shows up in the output. I am a developer, the number of directories I visit most frequently are my git repository root, 3 more directories inside the repo (the components I work most frequently), logs directory and tests directory for running tests. I wanted to figure out a quick way to jump between these directories.
I found the following post useful in finding the solution to my problem:
http://unix.stackexchange.com/questions/31161/quick-directory-navigation-in-the-terminal
The commands that helped me for this are pushd, dirs -v, the ability to refer to a directory as
'~<num>' where <num> is the number against the directory in 'dirs -v' output.
Idea is to pre-populate the list of directories every-time I start a terminal.
I don't want the order of this list to change, so that over time the number of times I will need to execute 'dirs -v' reduces because I remember the corresponding <num> for these directories.
I saved the list as follows in .bash_dirs file in my home directory.
pushd -n /home/pranithk/.scripts > /dev/null
pushd -n /usr/local/var/log/glusterfs/bricks > /dev/null
pushd -n /usr/local/var/log/glusterfs/ > /dev/null
pushd -n /var/lib/glusterd > /dev/null
pushd -n /home/pranithk/workspace/gluster-tests/afr > /dev/null
pushd -n /home/pranithk/workspace/gerrit-repo/tests/bugs > /dev/null
pushd -n /home/pranithk/workspace/gerrit-repo/libglusterfs/src/ > /dev/null
pushd -n /home/pranithk/workspace/gerrit-repo/xlators/mgmt/glusterd/src/ > /dev/null
pushd -n /home/pranithk/workspace/gerrit-repo/xlators/cluster/afr/src/ > /dev/null
pushd -n /home/pranithk/workspace/gerrit-repo/ > /dev/null
I added the following lines in my .bashrc file to load it every time the terminal is started.
if [ -f ~/.bash_dirs ]; then
. ~/.bash_dirs
fi
Now every time I start the terminal I have the directories already populated as below:
~
10:22:44 :) ⚡ dirs -v
0 ~
1 ~/workspace/gerrit-repo/
2 ~/workspace/gerrit-repo/xlators/cluster/afr/src/
3 ~/workspace/gerrit-repo/xlators/mgmt/glusterd/src/
4 ~/workspace/gerrit-repo/libglusterfs/src/
5 ~/workspace/gerrit-repo/tests/bugs
6 ~/workspace/gluster-tests/afr
7 /var/lib/glusterd
8 /usr/local/var/log/glusterfs/
9 /usr/local/var/log/glusterfs/bricks
10 ~/.scripts
Note that the number '0' is always associated with the present directory. The order of the directories is in reverse order of the list we have in the file because pushd keeps recently pushed directory first.
~
10:26:33 :) ⚡ cd ~8
/usr/local/var/log/glusterfs
10:26:36 :) ⚡ cd ~1
~/workspace/gerrit-repo (master)
10:26:39 :) ⚡
As shown above if I want to change to my logs directory all I need to type is 'cd ~8', if I want to change to my git repository root I type 'cd ~1'. So much typing and excessive pressing of 'tab' are saved :-).
Have fun and enjoy.
