This is actually found in *all* versions of less, at least since 1999, but the
environment variable that controls this feature isn't always set. An older
Ubuntu didn't set it, f'rinstance. That's:
export LESSOPEN='|lesspipe.sh %s'
...so less, when invoked, checks that LESSOPEN var and pipes files through
/usr/bin/lesspipe.sh , which checks the filename for a metric ton of common
patterns and attempts to invoke appropriate decompressers for those patterns.
Like "bzip2 -dc" for files ending in .bz2 , "bzip2 -dc | tar tvvf -" for files
ending in .tar.bz2 , and so forth.
