# zsh function script to run less on various inputs, decompressing as required.

# Thanks to zefram@fysh.org for a great deal of help in sorting this out,
|
|
# ie wrt syntax for unsetting members of arrays and eval "$(...)" when I
|
|
# asked for something better than . =(...)
|
|
#
|
|
# Use -zforce to pass through a display-formatting command
|
|
# zless -zforce 'bzip2 -dc' foo-no-dotbz2
|
|
# zless -zforce 'od -hc' foo-binfile
|
|
#
|
|
# If you can understand all of this without reference to zshexpn(1)
|
|
# and zshparam(1) then you either have a photographic memory or you
|
|
# need to get out more.
