What is your favorite command on terminal ?

  I  am an avid terminal user and try to work directly on $ prompt as far as possible.  If you are a command line geek, the following command can display  the 10 commands that you use most often.

  $  history | awk '{print $2}' | sort | uniq -c | sort -rn | head -10

Here is my output.

   73 sudo
     56 ls
     46 cd
     23 ifconfig
     20 dmesg
     11 ps
     10 ssh
     10 lsusb
      9 vi
      8 wget
