So why do you even mention it?

But the most important point is: _don't_ use 'less' on places other than

the end of a pipe! Less is a pager whose task is to pretty-print streams

so they are human readable. Less _does_ possible modify the stream. I'll

escape transmogrify certain control characters. If you try to use zless/grep

to search for a control sequence you might be up for a surprise ...
