This is one for people with a Unix-like operating system at home:
$ history | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head
141 make
94 cd
30 ls
27 open
24 python
23 ~/Projects/updateAlleged
23 ./totuschin
21 mv
20 xsltproc
10 man
The two non-standard commands are updateAlleged, which downloads some Atom and RSS feeds
that are inputs to the program that generates my home
page, and totuschin, which is a script for uploading an
updated version of one of my web sites to my ISP’s server (which is called tuschin). Each
site’s staging area has a different totuschin script.
The open command is used on Mac OS X to open a document in whatever is the usual editor (as one had double-clicked on it in a Finder window). So I often use open index.html to preview an HTML document before publishing it.
