Its a bash trick. Say your bash session looks like:

vim foo.java
javac foo.java
java foo
[repeat]

"!vim" expands to the most recent history item that starts with those
letters. "!vim" would execute "vim foo.java". This will save you millions
of keystrokes during your programming career, thus increasing the life of
your keyboard.

So now you can say:

!vim
!javac
java foo

(note that you can't say "!java" after "!javac", since the string "java"
matches the first letters of the history item "javac". Thus !java will
execute javac.)

Of course this works with any command.

ls /media/cdrom/path/to/folder
vim files.txt
# hey i forgot what was in my folder. what's that path again?
!ls
