Yesterday I was curious about how often I use certain Linux commands - i.e. ls, grep and git - and I knew all the previous commands have been stored in the history file. However, I don’t feel like going through the file and do the statistics all by myself.
Fortunately someone saved me with this one-line magic:
history | awk '{CMD[$2]++;count++;}END { for (a in CMD)print CMD[a] " " CMD[a]/count*100 "% " a;}' | grep -v "./" | column -c3 -s " " -t | sort -nr | nl | head -n10
And the result is:
1 378 75.6% git
2 44 8.8% ls
3 28 5.6% cd
4 10 2% python
5 6 1.2% spyder
6 6 1.2% history
7 4 0.8% vi
8 3 0.6% rm
9 3 0.6% cat
10 2 0.4% pip
Wow! I never realized git was so dominant in my daily command line engagement. All my works have been done in web-IDEs or local integrated IDEs such as pyCharm and IntelliJ, rescueing me from the burden of local environment configuration.
Git actions can also be done in the IDEs now but I feel like more code-y
with command line, maybe.
