Title: My tmux configuration

|
|
|
|
[tmux](https://tmux.github.io/) is a terminal mutiplexer. It lets you have multiples shells running in a single terminal emulator window and it keeps those shells running in the background should you need to close your terminal emulator.
|
|
|
|
I've played around with the configuration quite a bit to find settings that suit my needs. Here's what it ended up looking like :

This screenshot was done on Mac OS X, using the Terminal app and this [Solarized theme](https://github.com/tomislav/osx-terminal.app-colors-solarized).
|
|
|
|
I figured I'd share my tmux configuration here !
|
|
|
|
## Installing tmux
|
|
|
|
tmux is available on Debian. I suggest using the [jessie backports](https://packages.debian.org/jessie-backports/tmux) version :
|
|
|
|
`apt -t jessie-backports install tmux`
|
|
|
|
tmux is also available on Mac OS X using [brew](http://brew.sh/) :
|
|
|
|
`brew install tmux`
|
|
|
|
## tmux.conf
|
|
|
|
I used screen before tmux, so I configured the prefix key on C-a instead of C-b. tmux has the advantage of being *much* simpler to configure than screen.
|
|
|
|
If you want to use this configuration, simply copy the following in ~/.tmux.conf. This file is read by default when tmux starts.
|
|
|
|
If you simply want to try it out, copy it in a file somewhere else and have tmux load with the -f parameter (`tmux -f ~/tmux-test.conf`).

## Aliases
|
|
|
|
I also use two functions with tmux (in ~/.bash_aliases).
|
|
|
|
The first one creates a new "mytmux" tmux session if one doesn't exist yet, opens 10 shells and selects the first one.
|
|
|
|
```
|
|
mytmux() {
|
|
tmux has-session -t mytmux
|
|
if [ $? != 0 ]; then
|
|
tmux new-session -s mytmux -n $(hostname) -d
|
|
tmux new-window -t mytmux:1 -n $(hostname)
|
|
tmux new-window -t mytmux:2 -n $(hostname)
|
|
tmux new-window -t mytmux:3 -n $(hostname)
|
|
tmux new-window -t mytmux:4 -n $(hostname)
|
|
tmux new-window -t mytmux:5 -n $(hostname)
|
|
tmux new-window -t mytmux:6 -n $(hostname)
|
|
tmux new-window -t mytmux:7 -n $(hostname)
|
|
tmux new-window -t mytmux:8 -n $(hostname)
|
|
tmux new-window -t mytmux:9 -n $(hostname)
|
|
tmux select-window -t mytmux:0
|
|
fi
|
|
tmux attach -t mytmux
|
|
}
|
|
```
|
|
|
|
The second one changes the tmux window name whenever I ssh to a remote host, and switches the window name back to the name of my computer when I logout from the host.
|
|
|
|
```
|
|
if [ -n "$TMUX" ]; then
|
|
ssh() {
|
|
if [ $# -le 2 ]; then
|
|
tmux rename-window "${@: -1}"
|
|
command ssh "$@"
|
|
tmux rename-window "$(hostname)"
|
|
else
|
|
command ssh "$@"
|
|
fi
|
|
}
|
|
fi
|
|
```
|
