#ITERM TMUX WINDOWS#
Having status line and set of named windows inside it, I can turn iTerm to full-screen mode.Includes CPU, memory, online/offline status, battery, user, host, and date time.
A status line with system-wide information.Similar to tabs in iTerm, but you can give them a name iTerm2 vs tmux on local machine: benefits and drawbacks Benefits: So I’ve decided to give it a try, and today I can share benefits and drawbacks with you. When I was learning tmux, I had been returning to same question again and again. “Given iTerm already can create multiple virtual windows inside a single ‘physical’ window, can split, swap and resize panes, do I really need to use tmux on my local machine instead of iTerm?” Google here, Google there, after a while you grasp concepts like terminal multiplexing, windows, pane splitting, and understand tmux usage on remote machines to persist session state and survive abrupt disconnections.Īt some point of time, you might wondering about tmux usage locally. And you’ve heard about tmux, and decided to give it a try. So you’re using iTerm2 terminal emulator on OSX. tmux experience inside full-screen iTerm with 2 remote sessions nested in a local one This is 2nd part of “ tmux in practice” post series.
#ITERM TMUX HOW TO#
How to set up iTerm2 profile to override key mappings to trigger analogue tmux actions If that is the case, the socket connection will be lost the moment you log out from that session.By Alexey Samoshkin tmux in practice: iTerm2 and tmux Benefits and drawbacks of using iterm2 vs tmux locally. This means it might not point to the authentication socket of the ssh session running your tmux session if you have an earlier, regular ssh session open. NB The ~/.ssh/ssh-auth-sock gets set if it doesn't point to a valid socket. This is controlled by the administrator of the remote host. NB Your global sshd configuration might prohibit the use of the ~/.ssh/rc file. To use this name, set the SSH_AUTH_SOCK environment variable in your ~/.nf file, see the nf example below. This link can be set and updated in ~/.ssh/rc, see the ssh-rc example below. To avoid this, we can link the current authentication socket to a well-known name. You loose access to your ssh keys when you re-attach to your tmux session. The socket of the ssh agent to access the unlocked keys changes with every ssh login. Automatic ssh-agent socket handling and renewal You might want to set up two shorthands, one for normal ssh accesses and one for ssh with tmux. If you do that, the command to invoke becomes local> ssh tmhost The solution is either to set up a shell alias or a special Host configuration in your ~./.ssh/config file, as shown below in ssh-config. The final command we put together above is a much on the fingers if you use it a lot. The command is now local> ssh rmhost -t tmux -CC new -A -s tmux-main The session name is set using the -s flag, the -A flag specifies that new behaves like attach if the session exists. For that, we invoke tmux with the command new -A -s tmux-main.
The easisest way to is to create a session with a well known name and re-attach to that session later. If you want to re-attach to a remote session, you have to know its name. Naming the remote session to be able to re-attach This means invoking ssh with the -t flag: local> ssh rmhost -t tmux -CC To run tmux as the remote command argument to ssh, it need a pseudo-terminal attached. This will open a new tmux session in a new iterm window. The simplest way to get a remote tmux session into a window of iterm is to invoke it on the remote host local> ssh rmhost Tmux can be invoked in command mode using tmux -CC.
