How would you find a string of digits? Remember
[1234567890][1234567890]*
as an expression? In this directory is a file
"table" which contains some numbers. On every
line of the file, follow all numbers by the
character '%'. It should only take one 's' command.
Then rewrite the file and type "ready".
