A meme doing the rounds, here is the list of ten applications I’ve used the most. I appear to have a much smaller HISTSIZE than some.
dean@tir:~$ history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -rn | head
119 sudo
77 ls
34 apt-cache
25 ping
23 vi
20 man
20 cd
18 cat
17 ssh
14 iwlist
Guess who’s been having internet problems and is struggling with patchy access to a neighbours wireless. A lot of the sudo commands are me bouncing the network connection.
Like Wouter I have a habit of using “ls” when I’ve forgotten what I was going to do. I’ve also been using bash completion so I haven’t been “cd”ing as often as I used.
