New Tmux terminfo

I suggest changing all references to screen or screen-256color to tmux and tmux-256color as the new terminfo has been added to ncurses 6 (now in stable in Arch). You can find the announcement at http://invisible-island.net/ncurses/NEWS.html#index-t20150502 (the 6th point), or confirm by yourself by going to /usr/share/terminfo/t/. This mainly fixes the italic issue referenced here: https://wiki.archlinux.org/index.php/Tmux#Fix_reverse-video.2Fitalic_mode_in_urxvt. ~ Nicop06

Actually, it seems that the screen-256color terminfo is working since the upgrade to nurses 6. I suggest completly removing the section to avoid any confusion. Nicop06 (talk) 21:38, 5 January 2016 (UTC)

I've been using TERM=tmux-256color since the update. Overall things work, but there are some places and programs which have issues with it. The most common one is prezto (zsh config) doesn't use color for a lot of commands. I believe it fails to detect if term has color and falls back to color-less command arguments. I just filed a bug report for prezto. There were some other issues which I can't remember right now. Maybe some info notice should be added about this. MaikuMori (talk) 09:15, 6 January 2016 (UTC)

So it turned out it's not a bug in prezto, but coreutils. It's tracked here. The fix will be in coreutils-8.25. After that's fixed I see no reason to not use TERM=tmux-256color everywhere. My 2c. MaikuMori (talk) 21:45, 29 January 2016 (UTC)

Arch is using coreutils 8.30-1 now, let's move to tmux-256color? --Noraj (talk) 11:21, 12 September 2018 (UTC)

X clipboard integration

I updated the config options to be pasted into `tmux.conf` according to the new mode-table names in tmux. The old ones didn't work for me in vi-mode while the new ones do.

Can somebody check the emacs ones? I'm not sure about those. --jakobh ✉ 16:10, 1 March 2017 (UTC)

Tips and tricks

Can I add this section under Tips and tricks on the wiki?

# More friendly split pane
bind-key h split-window -h
bind-key v split-window -v

The description should be more descriptive than "More friendly split pane" - what is it actually doing? And the comment should be in the surrounding text, not in the code block. -- Lahwaacz (talk) 13:28, 12 September 2018 (UTC)

That was what is was going to do, you can now take a look at it [1].--Noraj (talk) 18:51, 12 September 2018 (UTC)

beware of 'exec tmux' if using Midnight Commander(without --nosubshell)

Because mc will run bash interactive like bash -rcfile .bashrc this means exec tmux also gets executed and thus create a small startup delay when running mc (and who knows what else). To test that mc does this, in ~/.bashrc after this line [[ $- != *i* ]] && return just add [[ -n "$MC_SID" ]] && echo "ran by 'mc' $MC_SID" >>/tmp/b and in another terminal run tail -F /tmp/b. To workaround this, only exec tmux if both MC_SID and TMUX env. vars are empty, ie. this [[ -z "$TMUX" ]] && exec tmux should probably be [[ -z "$TMUX" && -z "$MC_SID" ]] && exec tmux. Tested Midnight Commander 4.8.24-84-gcef0bb013, tmux 3.1a. Gentoo eshoes (talk) 01:27, 2 May 2020 (UTC)

256 colors

As of tmux 2.1, this is now tmux, or tmux-256color. 

I couldn't find the relevant change in the changelog. Further, setting this to tmux-256color didn't work for me on termite with tmux 3.1_b-1.

Although, using xterm-256color worked fine. MrHritik (talk) 23:33, 15 October 2020 (UTC)

Autostart with systemd

After setting this up, I was not able to run certain commands as shown below, apparently because I lost access to dbus. If it's not a problem, I'd suggest adding a note.

$ reboot
