Currently, a command frequency meme seems to propagate through Planet Debian, and I thought I'd run that one-liner as well. Some interesting results yielded:

At my laptop:

09:43:23 mbscholt@galadriel:~$ history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -rn|head -10
    331 cd
     35 ll
     21 vim
     12 cp
     10 mc
      9 PROMPT_COMMAND='pwd>&7;kill
      9 mv
      8 wget
      6 luna
      6 killall

As root on my server:

09:43:14 root@luna# history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -rn|head -10
    106 ll
     82 vim
     59 cd
     48 apt-get
     17 du
     16 /etc/init.d/apache2
     14 cp
     14 addgroup
     12 rm
     10 mc

One of my normal user screen sessions:

09:43:10 mbscholt@luna:~/projects/overload_iserv/server$ history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -rn|head -10
    108 vim
    102 ll
     67 cd
     46 svn
     46 cp
     17 du
     13 pine
     11 python
      9 wget
      9 grep

So it looks like I'm mostly moving from place to place looking what's there, and editing the hell out of it :) And it's funny, but I sometimes have those nervous twitches too.
