From the man page:
You may define an "input preprocessor" for less. Before
less opens a file, it first gives your input preprocessor
a chance to modify the way the contents of the file are
displayed.
What this means is that less(1) can automatically open up tar files,
uncompress gzipped files, and even display something reasonable for
graphics files.
You just need to put the following in your
.zlogin/.login/.bash_profile/whatever:
eval $(lesspipe)
or
eval $(lessfile)
lesspipe will toss the contents/info on stdout and less will read them
as they come across. This means that you don't have to wait for the
decoding to finish before less shows you the file. This also means that
you'll get a 'byte N' instead of an N% as your file position. You can
seek to the end and back to get the N% but that means you have to wait
for the pipe to finish.
lessfile will toss the contents/info on a file which less will then
read. After you're done, lessfile will then delete the file. This
means that the process has to finish before you see it, but you get nice
percentages (N%) up front.
If you have any questions, send me e-mail at <torin@daft.com>.
Mentioning less in the subject line will help.
