#print
You can now change a line of a file, using only the
commands already taught, by deleting the old line
and inserting a new one.
This is not a very convenient way to do that, so
there is a command 'c' (change) which combines
those operations.
5c
input text
here.
.
will delete line 5 and replace it by the lines
input text
here.
Note that the text following 'c', just like the text
after 'i' and 'a', must end with a line containing just
one '.' and nothing else.
This directory contains a file named 'short'
with six lines in it. Change the last line to read
new version of last line
and rewrite the file; then end with "ready".

which contains exactly
