What is your definition of a "superfluous blank line"? Is that all
blank
lines, or all consecutive blank lines where the number is more than
one?
If it's the latter, you may find "more -s filename" to your liking.
Thanks, Paul. I mean "all consecutive blank lines where the number is
more than one". Furthermore, I mean how to delete those blank lines
from the file.
$ more -s file > file.new
$ mv file.new file
Paul
Or better, "cat -s file > file.new" and avoid having to page through the
file.
You only have to page through a file when output is a terminal (not in
this case) IIRC.
