lesspipe.sh is an input filter for the pager less.
It is able to process a wide variety of file formats.
It enables users to deeply inspect archives and to
display the contents of files in archives without
having to unpack them before. That means file contents
can be properly interpreted even if the files are
compressed and contained in a hierarchy of archives
(often found in RPM or DEB archives containing source
tarballs).
The filter is easily extensible for new formats.
The input filter is a bash script, but works as well
as a zsh script. |
