Subject: The "set" utility outputs binary data
Date: Thu, 3 Dec 2015 15:05:58 +0100 [thread overview]
Message-ID: <20151203140558.GA17469@zira.vinc17.org> (raw)
The "set" utility outputs binary data (probably due to escape
sequences for coloring and so on in some parameters such as
prompts):
zira:~> set | grep ZSH
Binary file (standard input) matches
Though I could use the non-standard -a grep option, this is annoying.
I think that by default, "set" should quote non-printable characters
(including invalid byte sequences, I assume). I don't think that this
is even forbidden by POSIX, which already requires the shell to quote
some characters so that the output is "suitable for reinput to the
shell".
This is also important when the output is on a terminal.
