Top Ten:

1. sudo - nearly a third of the history
   
2. vim - main editor, also used to view files when I want highlighting or folding
   
3. apt-cache - searches for packages, or checking dependencies
   
4. ls - alias that adds '--color=auto'
   
5. lp - lots of print jobs with custom parameters
   
6. cd - lots of these from going up or down one level
   
7. git - breakdown: log, status, pull, clone, config, remote, init, describe
   
8. echo - testing regex makes this pretty high
   
9. cat - viewing file contents
   
10. mv - wrangling third-party code in /opt/ that I rebuild when there's an update
    

sudo breakdown:
* apt-get - installing/updating/cleaning up packages
* vim - editing system files
* mount - mucking around with university cifs shares
* systemctl - stuck with systemd for now, for fear I'd break commercial software
* mkdir - reorganizing installed scripts / libs
* chown - cleaning up permissions
* mv - reorganizing
* chmod - cleaning up permissions
* ufw - opening ports
* virsh - starting/configuring vm's

Here's a hack for the last bit:
