#print
A useful operation is to replace a string of several blanks
by exactly one blank. Note that you can't just write
s/ */ /
because the " *" willl match any number of blanks
including zero. Thus it will always match at the beginning
of the line, even if there is no blank there.
The normal sequence is
s/ */ /
which will only substitute for a string
that has at least one blank in it.
Try that command on the line in the file "line".
Then rewrite the file "line" and type "ready".
