Basic vimrc and tmux config for servers

readme.md

My minimal setup for a new server: tmux, Vim and RubyGems config.

curl -fsSL "https://gist.github.com/mislav/5706063/raw/install.sh" | bash -e

bashrc

curl -fsSL "https://gist.github.com/mislav/5706063/raw/bashrc" >> ~/.bashrc

chmod +x ~/.ssh/rc

ssh_rc.sh

#!/bin/sh
if [ -S "$SSH_AUTH_SOCK" ]; then
  # This gets executed by sshd on every client login, symlinking the forwarded
  # agent socket into a predictable location to be picked up by tmux.
  ln -sf "$SSH_AUTH_SOCK" "/tmp/ssh-auth-${USER}.sock"
fi

tmux.conf

## Optional: Ctrl-a as prefix instead of Ctrl-b
## I'm keeping C-b because my desktop tmux is set to C-a already
# set -g prefix C-a
# unbind C-b
# bind C-a send-prefix

# Faster escape sequences (default is 500ms).
# This helps when exiting insert mode in Vim: http://superuser.com/a/252717/65504
set -s escape-time 50

# start numbering windows from 1 instead of zero
set -g base-index 1

# syntax highlighting in Vim
set -g default-terminal "screen-256color"

# status bar contents
set -g status-left-length 15

# remove SSH_AUTH_SOCK from the default list of variables to be auto-updated
set -g update-environment "DISPLAY SSH_ASKPASS SSH_AGENT_PID SSH_CONNECTION WINDOWID XAUTHORITY"

# set it to the symlink set by ~/.ssh/rc
setenv -g SSH_AUTH_SOCK /tmp/ssh-auth-$USER.sock
