Iterm2 multiple panes windows#

My approach (not based on any particular insight) is to use iTerm tabs and panes to separate servers, and screen / tmux on the server to persist sessions. Personally, I'm used to tmux by itself at this point, so I've not leveraged this ability extensively - but if you are used to iTerm2 split panes, you can get the benefits of tmux (mostly screen-like session saving) with the iTerm aesthetics. ITerm2 can use tmux for it's split panes. Most terminal emulators send SIGHUP to all children which terminates them by default and thus you lose unsaved data (at least, shell and vim command history and other data stored in viminfo) and running processes and thus reopening means rerunning everything. With tmux it is normally as simple as reattaching session without losing anything.

I encourage you to give it a try and see if you like it.There is another advantage of tmux: what happens if you accidentally close iterm2? If you do it really by accident, you want to reopen everything again. This post summarizes my experience using its tmux integration and compares it to my existing workflow. ITerm2 is a fantastic product, it has a ton of features that you might not even know you need, I am a really new user and have not discovered all the ways that it can help my workflow yet. i2cssh uses iterm2 split panes and Send input to all sessions (cmd-shift-i) to send. With iTerm2, I lose the tmux status bar, and the nice colors I have set up. like tool for connecting over ssh to multiple machines.

My development environment is pretty sparse, there is not much eye candy around, but I do have a tmux status bar that is customized with colors that matches a Vim status bar scheme I like. Whereas when I was using plain tmux, the attachment is almost instant.

Iterm2 multiple panes windows#

With multiple tmux windows open, I find that iTerm2 takes some time to spawn all the tabs - I can see each tab being started one at a time. I use Better Snap Tool to place two iTerm windows side-by-side, which can each have multiple tabs. When I start my day I attach to the existing session that is running on the server. I initially thought that this would help with repetitive strains, since now I have to use a different key, Cmd, instead of relying on Ctrl for all my actions, but the context switch actually forced me to be more aware if I was working in a vim split or tmux pane. With iTerm2, this workflow doesn’t work anymore, I have to use to switch between tmux panes. For my workflow, I have a tmux split with vim above, and shell below (for running builds and tests). I use vim-tmux-navigator for easy navigation between tmux panes and vim splits, this means that (by default it’s ) will jump down the vim split below the active split, or the tmux pane below the active pane. The best I could come up with was to use the Meta key. I've been able to do it by 'Move Session to Window' on the pane with the session you want to keep 'New Tab' in the new window drag the tab you want over to another. Although I don't understand why it works. Now you can drag the title bar of the pane. I wanted this in tmux natively, but found that it didn’t have a way to recognize the Cmd key. Select 'Move Session to Split Pane' in the context menu, then click the pane. With tmux you need, and since is usually two keys, it’s effectively 3 keys. The tab strip in iTerm2 has tab numbers so it’s easy to hop to. CMD+OPTION+V Split pane top-bottom with new profile CMD+W Close current pane CMD+. I can probably come up with key chord to condense prefix+[ and ? to a single chord, but iTerm2 is still easier. It has features such as full-screen mode, window transparency, strong find-on-page feature, autocomplete and paste history. Right now to do this in Tmux I hit prefix+[, then ? to search upwards, then visually highlight my selection to copy. Program name: iTerm2 (System tools) iTerm2 is a terminal emulator for macOS.

ITerm2 mouseless copy, where you hit Tab while searching for a term, and the search term expands, then you can copy the term easily. With plain tmux, you can enable tmux mouse support and this lets you drag to resize panes, but you can’t do that to reorder windows, you’ll need to use a command for that. Seamless integration with iTerm2 tabs and panes means using mouse to easily drag and rearrange stuff. This integration even works for running tmux onto a host that I ssh to! I tried this workflow out for a couple of weeks, and eventually decided to switch back (to using a single iTerm2 window, ssh, and start tmux on my ssh destination). This means that tmux panes become iTerm2 panes, and tmux windows become iTerm2 tabs. I recently tried out iTerm2 (mostly for its integration for URLs, but it has a ton of other features).
