This tool is to visualize alias usage to parse command history. You can evaluate whether you use alias efficiently or not.

• It can show reduced types and more redusable types

• It can show how degree you use each alias

The visabliable shell scripts is the followings:

• zsh ($HOME/.zsh-history)

How to use:

$ alias | alias_metrics

Case Study:

$ alias | alias_metrics >>

You reduce 10.25% types (29814 / 290970)

If you use alias all, you can reduce more 3.98% types (11575 / 290970)

You often forget the following alias

alias   #used   #forgot forgot rate(%)  command

g       9       1530    99.42   git

_       0       210     100.00  sudo

gco     24      197     89.14   git checkout

ga      516     190     26.91   git add

...

<< I regist alias g=‘git`, but I often forgot to use this alias. This result show I typed “git” 1530 times. So I can reduce 1530 * 2 = 3060 types by typing “g” instead of “git”.

Todo:

• It can parse other shell scrpt(bash, csh, etc…)

• Add the function that recommends alias that can reduce your types by setting it

• Add the function that show Gold Standard

• Acceleration
