I have a possibly simple issue, but can't resolve it. I recently downloaded iTerm and have it setup using zsh, but when using tabs they are always duplicated.
For example I open two tabs A and B using CMD+T. I type ls in A and it works as expected, but tab B also does the same! If I use the standard macOS Terminal this does not happen. It also does not occur if open two separate iTerm windows.
Any ideas?
EDIT - iTerm version is Build 3.0.15
Found the answer myself.
User error on my part, and a difference between Terminal and iTerm. I was switching tabs using CMD+SHIFT+ARROWS. This moves the tab, you need to use CMD+ARROWS to jump between tabs.

I'm trying to setup the terminal on my new Mac to match the behavior of my old Mac, however I have run into an issue with my multiline prompt that has me stumped. I remember having this issue when I setup my old Mac several years ago, however I don't remember how I solved it.
My prompt (without color) looks like this:
╭─username ~ 130 ↵
╰─
When I press ⌘commandK in iTerm2 on my old Mac it clears the terminal window so that both lines of the prompt are shown at the top.
When I press ⌘commandK in iTerm2 on my new Mac it clears the terminal window so that only the second line of the prompt is shown at the top.
I have tried checking everything I could think of, I have checked:
Every dot file/directory in my home directory (copied them to the new Mac).
iTerm2 settings.
System settings (primarily keyboard shortcuts).
Various websites with instructions about setting up multi-line prompts.
Interestingly I have discovered that if I type clear iTerm2 will clear the screen and leave the top line showing on both Macs. However it first clears the entire screen, including the prompt, before bringing the prompt back (looks bad imo). However since it works differently ⌘commandK does I don't think that's what my old Mac is doing.
It's possible that I installed some program/script that somehow does this, but if so I'm not finding it locally or referenced online.
Does anyone know how I can get ⌘commandK working to clear the screen while keeping the top line of my prompt? I still have the old Mac so I can check/compare anything on it to the new Mac if there are any guesses about what settings I changed.
Edit:
I was able to find something that worked, however if anyone has any other suggestions I'll be happy to try them and accept any that I can make work that are less hacky than this (e.g. don't require another 3rd party app).
Edit: This doesn't work while a command is running, nor does it clear the scrollable history. So it's better than nothing but still doesn't behave like I want it to.
After coming back to my question SO associated a new question with an answer I was able to make work, although it feels extra hacky and wasn't what I had working before.
I found this answer which suggests using ⌃controlL to clear the screen. That does exactly what I want it to do (leaves the top prompt visible and doesn't flash) but with the wrong keybinding. Fortunately I was able to use an app I already have installed (BTT) to make ⌘commandK map to ⌃controlL only in iTerm2.
I recently got a mac. I was previously working on a laptop with ubuntu and I was using vim.
I now will discuss about vim in console (iTerm2 or the default terminal) and macvim.
The problem is that some binding don't work under mac. For example I had CTRL left/right for navigating between splits, CTRL up/down to move lines or blocks of code up and down, etc. They don't work anymore.
I had a bunch of plugins (nerdtree, powerline, etc.) that now look weird. Powerline doesn't display special characters in macvim and in terminal they are question marks.
In console, nerdtree looks weird and it doesn't display the special triangle character. If I hit return to open a file selected from nerdtree, it doesn't do anything. In macvim, it works ok.
Is there any guide on how to use vim on mac? Or what is the recommended way?
Nerdtree : let g:NERDTreeDirArrows=0
Powerline : Take a look at the part of strange characters in the document https://github.com/Lokaltog/vim-powerline
Navigating within splits with Ctrl + arrows work on mine. Can you post your vimrc, or try running vim without any configuration.
Ctrl+arrows to move lines and block doesn't work on mine.
Did you check which key was sent by your terminal to vim ?
Did you tried to set it manually ?
I had similar problems with emacs, including one keybinding I'm still not able to reproduce :(
I have the exact same config on my Mac and a Windows box at work, my Ubuntu box at home and a couple of VPSes. It works exactly the same on every platform in GVim/MacVim or in plain Vim.
Unfortunately I don't use either NERDTree nor Powerline but Vdt's answer seems to have all the info needed.
Some of the behaviors you describe are custom mappings. You should show us your ~/.vimrc (the old one on linux and the new one on the Mac, if there are differences) so that we can help you make it more portable.
Also, "looks weird" means nothing: please add a screenshot or two.
I want to be able to use Option-left and Option-right to skip words (and Cmd-left/right to go to beginning and end of lines) within Vim as it does at my shell prompt. My Iterm2 preferences have mappings to do this (e.g. Option-left to Esc-H and a one for option-right to Esc-F to skip over words), and this works in the shell locally or when ssh'd to a remote server.
When I use Vim locally or remotely, option-left works, but option-right does not. I suspect this is because Vim naturally listens for Esc-H, but not Esc-F. I am able to get around this by modifying .vimrc file to Esc-b to b and Esc-f to f, but I don't want to do this to every server I'm connecting to.
Similarly, I have the same desired setup for Cmd-left/right for going to beginning and end of a line. I can get this working in the shell via Iterm2 mappings (e.g. Cmd-left to Esc-[h), but Vim doesn't respond at all to this unless I map keys again (e.g. Esc-[h to ^).
Update: I just figured out how to get option-left/right working. I changed mapping in iTerm2 for these to be escape-[1;5D and escape-[1;5C respectively. I still want to solve the Cmd-left/right problem though (I changed my question's title to reflect this). Any ideas?
To mimic OS X's behavior of sending Cmd-left/right to the beginning/end of a line, I add the following mappings in iTerm2:
Cmd-left to escape-sequence [1~
Cmd-right to escape-sequence [4~
To mimic OS X's behavior of sending Option-left/right to the previous/next word, I add the following mappings in iTerm2:
Option-left to escape-sequence [1;5D
Option-right to escape-sequence [1;5C
Special thanks to this blog post for tracking down what I was missing with the cmd-left/right mappings
I'm using iTerm2 3.4.2 and there's actually a preset that you can select for your profile that enables this.
FWIW, dolan's answer didn't work for me on iTerm 2 1.0.0.20120203 on Mac OS X 10.7.3. His solution only inserted ~ and 5D/5C into my terminal when I pressed the shortcut keys.
Instead, I used the following solutions:
Cmd-left/right:

Option-left/right as well as option-delete:

YMMV, not sure why one set of solutions would work and not the other
I don't have MacOS, so I cannot exactly know your situation, but I recognize the problem from other OSes.
Basically, it would mean that the terminal sends keycodes that aren't understood by vim. I fixed it in the past by doing
TERM=something
export TERM
before invoking vim
E.g. in order to get all keys and syntax highlighting working on AIX 5.3 across Putty/screen, I needed to use
TERM=iris-ansi vim
There is a list of builtin terminal types if you pass a bad TERM
I'm trying to use the new iTerm app on my Snow Leopard Mac, but my Ctrl seems to be completely dead (as in non-responsive, as in nothing happens when I type Ctrl+a except for an outputed 'a') and I haven't found anything useful while googling. The closest match was this thread here on stackoverflow, but everything in Terminal.app works as it should.
And, even more strange - I can Ctrl+z myself out of applications, but I can't save files in Emacs (C-x C-s) or any other keyboard shortcuts that uses a Ctrl shortcut. And it's not local, since Ctrl is as broken on my iMac as it is on other unix computers I've sshed onto with iTerm. I've tried both in bash and zsh.
I've tried to remove all files concerning iTerm.app in my ~/Library/Application Support, and I've tried the very latest version (currently 13 h old) of iTerm I could lay my hands on, but to no avail.
Any ideas?
This seems to be an iTerm bug.
You can work around it by creating a key mapping in the profile settings.
Add a mapping for ^x so it sends 0x18 (which is the encoded form of ctrl+x).
I suggest to check this post to see if the ctrl key is enabled in your preferences

Did you try to configure key bindings for this terminal emulator as specified in the iTerm wiki:
http://code.google.com/p/iterm2/wiki/Keybindings
at last, have you try set -o emacs or set -o vi?
If it works, set it in your ~/.bashrc to run it at login.
I'm just meddling with OSX after a few years on Linux. There's a lot that I'm liking, but one thing that's slowing me down is that if I run the 'terminal' command via shortcut/spotlight/quicksilver, it whisks me off to any existing terminal in whatever space already has a terminal instance open.
I regularly like to pop up a terminal, run a quick command and then close it again, all the while staying in whatever desktop space I happen to be on.
...So, how do I do that on Mac?

Download this tool called Visor
It lets you quickly get a tabbed drop down terminal using a hotkey like Ctrl-`.
Insanely convenient for working in the shell.
Try this tool: https://github.com/nmadhok/OpenInTerminal
This is a really handy tool for programmers on Mac as it lets you open the folder directly in Terminal. You can select multiple folders to open them in multiple terminal windows. You can also select files to open the parent directory in Terminal. This application works with Finder as well as without Finder which is a plus!
