TERMINAL MULTIPLEXER

Wednesday, December 5, 12

what is tmux?


what is tmux?tmux is a terminal multiplexer: it enables a number of

terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single

screen. tmux may be detached from a screen and continue running in the background, then later reattached.

tmux vs. screen

syntax whether used interactively, as a key binding, or from the

So, how did I install tmux?


libevent

$ wget http://sourceforge.net/projects/levent/files/latest/download

$ tar xfz libevent-2.0.17-stable.tar.gz

$ cd libevent-2.0.17-stable/

$ /configure—prefix=/home/jlotito

$ make

$ make install

tmux

$ wget http://sourceforge.net/projects/tmux/files/latest/download

$ tar xfz tmux-1.6.tar.gz

$ cd tmux-1.6

$ ./configure—prefix=/home/jlotito

tmux cont.

$ ./configure—prefix=/home/jlotito CPPFLAGS=”-I$HOME/include” LDFLAGS=”-static -L$HOME/include -L$HOME/lib”

$ make

$ make install

$ export PATH=~/bin:$PATH

$ tmux -V

tmux 1.6


If you have permissions,you can do it.


sandbox vim: 7.0my vim: 7.3


:set rnu



but you shouldn’t have to set things up


$ cd$ mkdir bin$ cp ~/../jlotito/bin/tmux ~/bin$ export PATH=~/bin:$PATH


$ tmux


prefix = CTRL + bThis is the default prefix

It’s run before every command

prefix dThis means type ‘CTRL + b’ and then type ‘d’.


prefix dDetaches from the current tmux session

In other words, it exits tmux


detachdo it


$ tmux attachreattaches to the tmux session


do itnow


Multiple sessionsYou can have them

We won’t discuss them today


prefix ccreate a new window (or tab)


prefix #‘prefix 1’ takes you to tab #1


prefix wprovides a list of windows available

‘j’ and ‘k’ to scroll the selections


prefix %That’s not 5, but ‘%’, which means

prefix SHIFT+5

This splits the pane in half


prefix xIn the lower portion of tmux, you’ll see it ask you:

kill pane 2? (y/n)

type ‘y’


prefix “split horizontally


prefix oswitch between panes


prefix CTRL + omove panes around layout


PREFIX SPACEchange layout of panes


Try scrolling in a panehaha


prefix [CTRL u : up a lot

CTRL d: down a lotLove alot.j : up a line

d : down a lineq: quit


Configuration$ touch ~/.tmux.conf


CTRL + B is awkward# Prefix Configset -g prefix C-aunbind C-bbind C-a send-prefix

Easy Pane Spitting# Splitting Panesbind \ split-window -hbind - split-window -v


Easy Pane Movement# Movement keys, vim stylebind h select-pane -Lbind j select-pane -Dbind k select-pane -Ubind l select-pane -R

Pane Resizing# Pane resizing, vim stylebind H resize-pane -L 5bind J resize-pane -D 5bind K resize-pane -U 5bind L resize-pane -R 5


Try the pane resizingDon’t forget to run this command

prefix r


Let’s make resizing easier by repeating

# Pane resizing, vim stylebind -r H resize-pane -L 5bind -r J resize-pane -D 5bind -r K resize-pane -U 5bind -r L resize-pane -R 5


resizeprefix L

-r You can hold it down, and it will keep moving

we were using tmux 1.6latest is tmux 1.7


new in 1.7

tmux configuration files now support line-continuation with a "\" at the end of a line.* New option status-position to move the status line to the top or bottom of the screen.* Enforce history-limit option when clearing the screen.* Give each window a unique id, like panes but prefixed with @.* Add pane id to each pane in layout description (while still accepting the old form).* Provide defined ways to set the various default-path possibilities: ~ for home directory, . for server start directory, - for session start directory and empty for the pane's working directory (the default). All can also be used as part of a relative path (eg -/foo). Also provide -c flags to neww and splitw to override default-path setting.* Add -l flag to send-keys to send input literally (without translating key names).* Allow a single option to be specified to show-options to show just that option.* New command "move-pane" (like join-pane but allows the same window).* join-pane and move-pane commands learn "-b" option to place the pane to the left or above.* Support for bracketed-paste mode.* Allow send-keys command to accept hex values.* Add locking around "start-server" to avoid race-conditions.* break-pane learns -P/-F arguments for display formatting.* set-option learns "-q" to make it quiet, and not print out anything.* copy mode learns "wrap-search" option.* Add a simple form of output rate limiting by counting the number of certain C0 sequences (linefeeds, backspaces, carriage returns) and if it exceeds a threshold (current default 250/millisecond), start to redraw the pane every 100 milliseconds instead of making each change as it comes. Two configuration options - c0-change-trigger and c0-change-interval.* find-window learns new flags: "-C", "-N", "-T" to match against either or all of a window's content, name, or title. Defaults to all three options if none specified.* find-window automatically selects the appropriate pane for the found matches.* show-environment can now accept one option to show that environment value.* Exit mouse mode when end-of-screen reached when scrolling with the mouse wheel.* select-layout learns -u and -U for layout history stacks.* kill-window, detach-client, kill-session all learn "-a" option for killing all but the current thing specified.* move-window learns "-r" option to renumber window sequentially in a session.* New session option "renumber-windows" to automatically renumber windows in a session when a window is closed. (see "move-window -r").* Only enter copy-mode on scroll up.* choose-* and list-* commands all use "-F" for format specifiers.* When spawning external commands, the value from the "default-shell" option is now used, rather than assuming /bin/sh.* New choose-tree command to render window/sessions as a tree for selection.* display-message learns new format options.* For linked-windows across sessions, all flags for that window are now cleared across sessions.* Lots and lots of bug fixes, fixing memory-leaks, etc.* Various manpage improvements.
