Hello:
I searched here for "vi -c" but found no hits.
How can I use vi -c to remove ALL empty lines, regardless of how many?
I tried
<code>
vi -c ":g/^$/d | wq" filename
</code>
but I have to run it several times.
This is NOT homework. :)
Thanks for your time. (3 Replies)

RMDIR(1) General Commands Manual RMDIR(1)
NAME
rmdir, rm - remove (unlink) directories or files
SYNOPSIS
rmdir dir ...
rm [ -f ] [ -r ] [ -i ] [ - ] file ...
DESCRIPTION
Rmdir removes entries for the named directories, which must be empty.
Rm removes the entries for one or more files from a directory. If an entry was the last link to the file, the file is destroyed. Removal
of a file requires write permission in its directory, but neither read nor write permission on the file itself.
If a file has no write permission and the standard input is a terminal, its permissions are printed and a line is read from the standard
input. If that line begins with `y' the file is deleted, otherwise the file remains. No questions are asked and no errors are reported
when the -f (force) option is given.
If a designated file is a directory, an error comment is printed unless the optional argument -r has been used. In that case, rm recur-
sively deletes the entire contents of the specified directory, and the directory itself.
If the -i (interactive) option is in effect, rm asks whether to delete each file, and, under -r, whether to examine each directory.
The null option - indicates that all the arguments following it are to be treated as file names. This allows the specification of file
names starting with a minus.
