Color output your terminal does not seem to support.

try 'zypper lu | lv' instead. lv supports ansi escape characters; less does not. This is rather a 'bug' of less than a problem of zypper since a pure 'zypper lu' should give a colored output as well. Coloring makes the output of terminal programs much more readable. I would welcome this to be used much more heavily. If we wanna do sth. about that issue, we should at first install lv by default and perhaps then modify less to interprete ANSI-escape-sequences correctly since that is easier than making all users learn about a new program like lv. For a guide on how to use ANSI-escape-sequences with your own Linux programs just have a look at http://www.elstel.com/ColorConsole (page will go online, soon; in a day or so.).

less -R will do the right thing (maybe amending LESSANSIENDCHARS), hence just do 'LESS="$LESS -R"' in .bashrc or something. But really, zypper should check isatty(1) before activating color output.

I disagree. less (and similar programs) should _not_ by default interpret ANSI sequences, otherwise looking at files that contain arbitrary binary crap could fiddle with the terminal settings. Optional is okay. Ciao, Michael. -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

This is some meta-mode switch control sequence sent by readline when it is initialzed. See https://www-old.cae.wisc.edu/pipermail/bug-octave/2008-March/005294.html It's fixed in factory by avoiding readline initialization if the output is not terminal (git show 50e3c8).

Isn`t there any possibility to see if a non-tty recipient understands ANSI-ESC sequences like 'less -R'? -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

Nope. You can detect "active" recipients via an inquiry control code (which then basically sends back an terminal identification sequence), but not passive ones, like less or the like.
