Is it meme o’clock already? Well, if you really must know…

toto:~ richard$  history|awk '{a[$2]++} END{for(i in a){printf "%5d\t%s\n",a[i],i}}'|sort -rn|head
  130 cd
  110 ls
   50 ssh
   20 exit
   15 scp
   14 cp
   11 svn
   11 sudo
   11 openssl
   11 java

I’m surprised there’s not some find, grep and mate in there.
