On ubuntu 14.04 LTs, when running byobu, I keep seeing strange numbers appear, such as 127 in the screenshot below:

enter image description here

What does this 127 represent, and if it is nothing important, how do I get rid of it? I don't remember seeing this in Ubuntu 12.04.

http://www.tldp.org/LDP/abs/html/exitcodes.html -> code 127 means 'Command not found'. It is the value exited of previous command (of course, when the value is other than 0, 0 means success).

Is the exit status code of last command.

To disable it use:

byobu-disable-prompt

More information you can find here.

  • to "complete" this answer by using @enedil answer, the numbers represent "exit codes". A feature that is not in Ubuntu 12.04's byobu May 8, 2014 at 10:30
