I'm on macOS and I set English as the locale except for LC_TIME:

~ $ locale
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="ja_JP.UTF-8"
LC_ALL=

Previously, the output of type command was (naturally) English:

$ type bash
bash is /opt/homebrew/bin/bash

However, after upgrading to bash 5.3, the output is now in Japanese:

~ $ bash --version
GNU bash, version 5.3.0(1)-release (aarch64-apple-darwin24.4.0)

~ $ type bash
bash は /opt/homebrew/bin/bash です

Why? --- By the way, I also have a very surprising result. type command seems NOT to be stateless. Specifically, it seems the command *remember*s the last environment in which it was previously executed:

~ $ echo $LANG
en_US.UTF-8

# The output is in Japanese.
~ $ type bash
bash は /opt/homebrew/bin/bash です

# When I override $LANG, the output is in English.
~ $ LANG= type bash
bash is /opt/homebrew/bin/bash

# As I used *simple command* in bash,
# the value of $LANG is still en_US.UTF-8.
~ $ echo $LANG
en_US.UTF-8

# Now, surprisingly, type outputs in English.
~ $ type bash
bash is /opt/homebrew/bin/bash

--- Current workaround is to use /usr/bin/type instead of the shell builtin type:

~ $ builtin type bash
bash は /opt/homebrew/bin/bash です

~ $ /usr/bin/type bash
bash is /opt/homebrew/bin/bash

--- Output of typeset -p | grep -e LC_ -e LANG (requested by a comment):

~ $ typeset -p | grep -e LC_ -e LANG
declare -x LANG="en_US.UTF-8"
declare -x LC_TERMINAL="iTerm2"
declare -x LC_TERMINAL_VERSION="3.5.14"
declare -x LC_TIME="ja_JP.UTF-8"

When I try to apply my last command on iterm2, and that command is a bit longer than 1 line, the command history only saves part of the command, making the history feature useless to me. How can I configure iterm2 to save the entire command I last executed, so I can use it again, despite its size?

I have set up iTerm2 to change its profile when I ssh to a specific machine. This works as intended (I am using zsh and oh-my-zsh). The main thing I do for this is in my ~/.zshrc file: echo -e "\033]1337;SetProfile=\a" This sets the colors as defined in "Colors" in iTerm2's "Profile". So far, so good. I have downloaded the [color profile called "Harper"](https://iterm2colorschemes.com/) and would like to use it with the "41m column" (in lack of a better term). As far as I understand that basically means I have to set the terminal's background color to "red" (which is what "41m" means). But I cannot figure out how to do this... I have tried (for example): echo -e "\033]1337;SetProfile=\a" echo -e "\033]1337;SetColors=bg=c00\a" or echo -e "\033]1337;SetProfile=\a" echo -e "\033]1337;SetColors=bg=f00\a" Which makes iTerm show a red background and use (for example) the foreground colors defined in the Harper color scheme. But that's not what I want. My question is very similar to (not to say the same) what was asked in a Stackoverflow question: [Iterm2 colors - using the 42m or 41m options](https://stackoverflow.com/q/34257198) . But that question does not have an answer. By the way, I know that most instructions on the Internet seem to use a different OSC command (50 instead of 1337), but according to [iTerm2's documentation](https://iterm2.com/documentation-escape-codes.html) , that is outdated: > The OSC command 50 used to be used but it conflicts with xterm, so it is now 1337. Is it even possible to do what I intend?

Every time I type Shift+Space in vim, it undoes all changes to the file that have not yet been written. I would like this to not happen, as it is extremely easy to press Shift+Space by accident. I am using iTerm2, and am ssh'ed into a remote machine. When I use vim (in iTerm2) on my local (OSX) machine, this issue does not occur. When I use the default terminal instead of iTerm2, this does not occur, even when ssh'ed into the same system. So: only the combination of iTerm2 + being in an ssh session seems to cause problems. I have never modified any vim keybindings; I have no ~/.vimrc, and :verbose Map doesn't show any binding. This makes me think this is an iTerm2 issue - but I don't understand why it would not cause this problem when running a shell on my local machine. Are there any iTerm2 profile settings that apply only in ssh? Or should I look elsewhere for this issue?

Any command I run (aside from clear) results in a double zsh prompt -- the first one showing the unformatted prompt, the second one showing the correct, formatted prompt. My ~/.zshrc file:

I recently started to work in a shared Linux cluster that a version of gnu-screen that I consider unacceptably old (4.01, from 2006). I was not able to convince the system's administrators to install a more recent version of gnu-screen, so I installed my own off my home directory, using conda. Unfortunately, even after I installed my long-trusted ~/.screenrc file, my conda-installed instance of gnu-screen does not work well at all. For example, the backspace key does not erase the character to the left of the cursor; instead, it behaves like the space key, at least as far as what shows up on the screen. Hitting the C-r key, which I use *all the time* to search my history, disfigures my screen grotesquely. Other than gnu-screen's "command key" (which I have set to C-h), pretty much any chord involving Ctrl is messed up. Etc. I should emphasize that all these problems emerge only after I start a new gnu-screen session, using my conda-installed instance of gnu-screen. Outside of screen, or when I use the ancient /usr/bin/screen, my terminal behaves normally. Still, I suspect that the problem may have something to do with my TERM variable's setting at the time of invoking screen (namely TERM=xterm-256color), and/or the terminal emulator I am using (iTerm2 running on OS X), but I don't know how to go beyond these hunches. When I search online for solutions to this problem I come across massive amounts of trial-and-error. Is there a systematic, reasonable way to troubleshoot this problem?

I have my iTerm2 configured with a shortcut to delete a word (keyboard mapping of Hex code 0x17). However, I want it to delete until reaching a whitespace: Current: cd hello-world -> cd hello- Wanted: cd hello-world -> cd Is there a way to configure the non-word separators somehow? Or to achieve this by other means?

Why would my iTerm2 command prompt change to user@192 instead of my machine name? And how do I prevent it from changing to user@192?

I cannot get commandline tools that use ncurses to work in iTerm2. They either fail or fall-back to some other UI if they have it (e.g. text only). Example for VLC (installed via Homebrew):

% /Applications/VLC.app/Contents/MacOS/VLC -I ncurses
VLC media player 3.0.16 Vetinari (revision 3.0.16-0-g5e70837d8d)
Error opening terminal: xterm-256color.

I have tried with different values for the TERM (xterm, rxvt, vt100) env variable and got the same error. More details about the iTerm2 session settings:

% env | grep -i term
LC_TERMINAL_VERSION=3.4.9beta1
ITERM_PROFILE=Default
__CFBundleIdentifier=com.googlecode.iterm2
TERM_PROGRAM_VERSION=3.4.9beta1
TERM_PROGRAM=iTerm.app
LC_TERMINAL=iTerm2
COLORTERM=truecolor
TERM=xterm-256color

Worth mentioning that this is only happening in an M1 MacBook Pro running macOS BigSur 11.5. With the same iTerm settings ncurses apps work fine in an Intel Macbook Pro running the same OS version.

Using iTerm2 with tmux and zsh. I have an issue that new tmux panes doesn't source ~/.zshrc file I have customized my terminal (when running source ~/.zshrc manually it works) but when opening new pane (C+b and c) it doesn't source the file ~/.tmux.conf

I want to permanently clear the bad returns in iTerm2. I have used "Clear" and "command-k" etc including with "l" shortcuts but it apparently only clears the current terminal. If I restart the terminal, the bad returns appear at the beginning. How can I clear them permanently? Thank you for any insight.

I am learning terminal tips. In this tutorial, the guy says that Ctrl + U deletes everything from the cursor until the end of line. In my case, it always deletes the whole line. I am using zsh on macOS.

To clarify, "automatically quits scrollback" mode means byobu goes into normal mode and jumps to the bottom, and I can't just go back to the point I previously scrolled up to. I am also using iterm2 and use mouse (set in .tmux.conf) to enter scrollback mode, not sure how it affects the configurations.

I'm trying to use iTerm2 profile triggers on my mac to change the prompt if I leave my home directory. This rule should only apply when the node I'm on has a hostname of headnode. The prompt will also include the machine's location in parenthesis after the hostname. I'm trying to build a regex that will match any directory unless it includes ~. So it should match: [jbutryn@headnode (us-west-a) /]$ but not: [jbutryn@headnode (us-west-a) ~]$ or [jbutryn@headnode (us-west-a) ~/tmp]$ etc. Currently I'm building my regex like this: \[.*\@headnode.*(?!\~).*]. But that matches all examples above. Does anyone know what I'm doing wrong? Thanks!

Issuing SIGINFO (e.g. by pressing ^T) while a terminal process is running usually results in a printout of a line

load: 2.93  cmd: sleep 7826 waiting 0.00u 0.00s

If I have written the tool that's running, I can make it catch the signal SIGINFO and react to it (e.g., by printout of certain information, like dd or ping are known to do). However, the above line is printed nevertheless. I wonder who is responsible for its being printed, and if it is possible to suppress it. FYI: I'm using zsh inside iTerm2 on MacOS.

I would like to start a tmux session on a separate window in iTerm2. Now I'm writing my own configuration script to launch the session. tmux new-session -s dev -n main -d tmux send-keys -t dev "cd $DL" C-m tmux split-window -h -t dev tmux split-window -v -t dev -p 30 tmux resize-pane -x 70 -y 20 tmux attach -t dev This starts a new session but the window is on the window I execute the script, not the new, separate window in iTerm2. So I changed the first line (tmux new-session -s dev -n main -d) to tmux -CC new -t dev, but then although the session starts in a new window, it does not have the split and the resize. It seems to only open the new session in a new window and that's all. How can I make it launched in a new window with all the initial settings including the directory change, split window, etc...?

iTerm2 runs slowly when using tmux (without -CC control mode integration). It is clearly designed with the intention of using -CC. However, I don't like the desktop window management of tmux windows/panes. I want tmux keyboard shortcuts and everything in a single iTerm2 window. Is there a way to disable tmux integration in iTerm2 so that I can tmux without using -CC? And so that it won't lag? If you are having difficulty trying to reproduce, try opening 2 tabs attached to the same tmux session. Compare it's I/O performance to the system terminal attached to the same tmux session.

I just got a new macOS system, and the output text in the terminal is not properly formatted. Every line is indented every time a newline is printed, instead of "on top" of each other so it ends up looking like a waterfall of words. I am using iTerm2. This happens no matter which shell I use. Anyone know what I can do to fix this?

I am using iTerm2 on my mac pro, and using fish as my shell. Every time I have a process running and I break it by pressing ctrl+c, the arrow keys stops working after and starts emitting ^[[A etc. Attached a screenshot to my iTerm2 preferences > Profiles [Default] > Terminal
