I recently started to use tmux and like it much, but its green bottom bar is a bit distracting, is there a way to change its color? or a way to hide it?

There are many options given in the manual. (See the OPTIONS section.)Create an RC file: ~/.tmux.conf. The contents below enables UTF-8, sets the right TERM type, and draws the status bar with a black background and white foreground.set status-utf8 onset utf8 onset -g default-terminal screen-256colorset -g status-bg blackset -g status-fg whiteIn FreeBSD 10.1, I have had to add -g to the UTF directives.set -g status-utf8 onset -g utf8 onOn UTF-8, many SSH clients require one to explicitly define a character set to use. For example, in Putty, select Window -> Translation -> Remote character set: UTF-8 and select Use Unicode line drawing code points.And to turn off the status bar...set -g status offOn colors from the manual...message-bg colourSet status line message background colour, where colour is one of:    black, red, green, yellow, blue, magenta, cyan, white, colour0 to    colour255 from the 256-colour palette, or default.So, to list the available colors, first create a script, maybe colors.sh:#!/usr/bin/env bashfor i in {0..255} ; do    printf \x1b[38;5;${i}mcolour${i}\ndoneNext, execute the script, piping to less:colors.sh | less -rThis produces a list of colors, 1-255, in this format:colour1[...]colour255Pick a color from the list, perhaps colour240, a shade of grey. In ~/.tmux.conf, use this value to set the desired color:set -g status-bg colour240In Fedora 17, 256-color terminals are not enabled by default. The official method used to enable 256-color terminals by default is given on the Fedora Project Wiki. Follow that guide, or, as a per-user solution, create an alias for tmux to force 256-color support with the -2 switch.alias tmux=tmux -2Then start tmux to test it.Note that, as @ILMostro_7 points out, it would not be correct to set the TERM type for tmux from, for example, ~/.bashrc. Each tmux pane emulates a terminal - not the same thing as an xterm. The emulation in tmux needs to match screen, a different terminal description, to behave properly; but, the real terminal does not need to do so. It's description is xterm-256color.
