Lets say, the prompt is as below
run_scripts >
How to set that terminal tab title same as prompt
i.e Terminal tab tile also should be
run_scripts>
So that terminal title should dynamically update when the prompt changes.
Many terminals emulators are able to understand the special escaping : "\033]0;foo\007".
I know its a old post but i saw it today :
Here is the answer:
title `pwd`
if title command does not works in your shell then:
write a shell script with follwing contents (filename = title)
#!/usr/bin/tcsh -f
echo "^[]2;$1^G^[]1;$1^G"
then:
chmod +x title (give this script executable permission)
type:
title `pwd` <enter>
This single line command will change the title of the tab.
Simply run the command from terminal tab which title need to change-
PS1=$PS1"\[\e]0;My_Tab_Name\a\]"
Some Info:
The PS1 is a primary prompt variable which holds the characters displayed at the terminal prompt. You can set it whatever you want. However the above command will make it only work for current terminal session. Once you close the terminal and opena new one, it'll be the default one.
To make it permenant edit the PS1 variable in ~/.bashrc or ~/.zshrc file.
Benefits-
It help us to easily navigate over the tabs.

In macOS Catalina (10.15.6), I want to use zsh for Terminal sessions. Formerly I had been using the default bash. For bash, I had a .profile containing the line
export PS1="[\u#\h:\w]$ "
which gave a prompt of the form:
[me#myhost:current-dir]$
I want something similar for zsh, but without the user-name#host-name prefix and with # instead of $ for the actual prompt.
In a zsh Terminal session, the command
PROMPT='[%/]%% '
gives the expected prompt, with the current directory enclosed in square brackets.
Of course I don't want to enter that manually each time. Instead, I want to set this in .zprofile. So in .zprofile I included the line
export PROMPT='[%/]%% '
However, that does not work as expected -- the prompt now has the form:
me#myhost current-dir %
Question: How can I get the zsh prompt to have the desired form as follows?
[current-dir] %
Just add the following export to ~/.zshrc, otherwise it won't work.
export PROMPT='[%1~] %%'
That will give you the following, my directory name is test-workflow-branch-only
[test-workflow-branch-only] %
NOTE: This will give you [~] % when in ~/ directory so don't be alarmed when you see that
UPDATE - per comment questions
We add it to ~/.zshrc as this file gets sourced in all interactive shell configurations. The file ~/.zprofile are for commands that we want to execute when we log in, therefore a non-login shell won't source this file.
Thanks for info from Edward Romero. My critique of answer is that it contains four wasted characters, '[',']',' ','%'. Using instead PROMPT='%d>' yields the nice clear absolute path, something like this:
/Users/myuser/test-workflow-branch-only>
In any case, nice to get this headache behind me, and begin reaping the wonderful benefits of using zsh, whatever they may be.
TLDR;
I need a way for .zshrc to automatically be sourced each time a command is executed. PROMPT needs to be updated each time a command is executed in order to show relevant information in the prompt.
Reason
I use Watson cli for tracking time. On my previous bash setup, I prepended my prompt ($PS1) with a symbol that indicates whether the timer is running or not (red/green). I have mimicked this functionality with Oh My Zsh, as follows (in the theme file):
WATSON_DIR="$HOME/Library/Application Support/watson"
watson_status() {
local txtred="${fg_bold[red]}"
local txtgrn="${fg_bold[green]}"
local txtrst="${reset_color}"
# Started
local status_color="$txtgrn"
# Stopped
if [[ $(cat "$WATSON_DIR/state") == '{}' ]]; then
status_color="$txtred"
fi
echo -e "$status_color""◉""$txtrst"
}
PROMPT="╭── %{$(watson_status) $fg_bold[green]%}%~%{$reset_color%}$(git_prompt_info) ⌚ %{$FG[130]%}%*%{$reset_color%}
╰─➤ $ "
Current issue
The icon will indicate the color of the state at the time that .zshrc was executed. For example, if the timer is running and the icon is properly indicating green, stopping the timer will not cause the icon to turn red. In order to see the icon change color, I have to source .zshrc.
This indicates that the function watson_status() needs to be run each time a command is executed, to give the latest status at the time of the command
I recently ported some prompt code from bash to zsh - on OSX Big Sur - and these were the two big "things to know" for me:
add setopt PROMPT_SUBST to your .zshrc. This "allows for functions in the prompt"
use single quotes when defining your PS1 / PROMPT. If you use double quotes, then the whole string will be evaluated once when the terminal starts, and then that evaluated value is "re-executed" every time the command changes. But you want the functions to be re-evaluated, not the output of the function at the time when the terminal is created.
Easiest example I used to confirm I had it working:
# print_epoch() { date '+%s' }
# this is what you want
# export PS1='$(print_epoch) > '
# this is not what you want
# export PS1="$(print_epoch) > "
Also worth noting PS1 and PROMPT are interchangeable
Extra:
While we are sharing here is my fairly minimal echo my user, directory, and git branch PROMPT with some colors and a pretty leaf:
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'
}
setopt PROMPT_SUBST
autoload -U colors && colors
export PROMPT='%n %~ %F{blue}🌿$(parse_git_branch)%f > '
noting that:
%n prints name
%~ prints directory relative to home
%F{blue} changes text to blue
%f resets color

How would I hide the computer name in the prompt while using the terminal?
At the moment it shows both username and computer name like so:
It would save some space by removing anwarchoukah#anwars-mbp, seeing as I actually know who I am:)
Try to add export DEFAULT_USER=$USER to your .zshrc file
On MacOS 10.15 Catalina:
Open the file /private/etc/zshrc in a text editor
Locate the comment: # Default prompt
Modify the line that looks like this: PS1="%n#%m~ %& # "
Save the file. You will be prompted to enter a password to save it.
Load a new Terminal window.
For example, you can:
Remove "%n#%m" to get rid of both the username and computer name
Remove "%n" to get rid of the user name
Remove "%m" to get rid of the machine name
step 1. one your .zshrc file by vim .zshrc
step 2. go to end of your file.
Paste this code:
careful indent again your code
prompt_context() {
if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
prompt_segment black default "%(!.%{%F{yellow}%}.)$USER"
fi
}
EDIT - explaining what this does
This will remove the machine#user name from the prompt IF:
- you are not logged in as the default user
- you are not in an ssh client shell
For most people, not needed, but if you regularly ssh to other machines and have multiple terminals open (eg remote sys admin type work) then this is extremely useful so when you look at your terminal you know which machine and user you are logged in as inside that terminal.
If you don't need/manage that type of complexity then use one of the other answers to just modify your export PROMPT/PS1 value.
* WARNING *
If you are using a custom shell or theme, this might not work and although the prompt will no longer show your computer and username it will keep throwing the error:
prompt_context:2: command not found: prompt_segment
For example, you can see with this (very popular) powerlevel9k it does not work. This is because the Powerlevel9k theme uses it's own magic and you simply add commands to your ~/.zshrc file to get the same result, eg:
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context)
More info on that here.
Open up .zshrc, find the line reading export PS1 or maybe export PROMPT.
Remove the variable that is used for the hostname, could be %m or %M.
Zsh on Archlinux wiki
You can use colors and also have a prompt (or some information) on the right side.
I like this approach (on my mac)
put in .zshrc
PS1="%n$ "
The terminal will look like
username$
Just add prompt_context() {} to .zshrc
Unfortunately none of the .zshrc changes worked for me.
Machine : Mac M1, Big Sur 11.4
So this is what worked.
I Navigated to where the ZSH themes were installed, opened my theme, agnoster in TextEdit, and modified the configuration where it chooses what do display, which by default is $username#%m.
Note : %m here is the machine name.
Here is a screenshot of delta. Yellow is what I did, Green is the default setting from github version of agnoster theme.
Voila this worked. Now to me it just displays the machine name, as I intended.
Hope that helps. Many links and SOF posts only made me click that solution.
Set DEFAULT_USER in ~/.zshrc file to your regular username. You can get your exact username value by executing whoami in the terminal.
Something like this:
export DEFAULT_USER=username
If you are using PowerLevel9k theme, there is a variable POWERLEVEL9K_CONTEXT_TEMPLATE that can change the view of your hostname and computer name.
The default option is %n#%m,
%n -> username
%m -> machine name
to hide hostname:
Open the .zshrc file using sudo nano ~/.zshrc
Add the line
POWERLEVEL9K_CONTEXT_TEMPLATE="%n" at the end of .zshrc file
Save the file.
Maybe this will help you [ Open Profile => Shell ]
PS1="~ $: ";clear;
Just add this to your ~/.zshrc file:
export DEFAULT_USER=\`whoami`
Install Oh My Zsh is the easiest solution for me:
https://ohmyz.sh/
One liner install:
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
Result:
If you're using Powerlevel10k, then you can run p10k configure and configure the output a bit.
My username and computer-name was gone after having gone through it. It feel less hacky, than the other solutions here.
I don't know why I can't find a simplified solution.
So here is the simplified one.
Just jump into the themes directory,
# ~/.oh-my-zsh/themes
Select the theme, as I have been using
# vim agnoster.zsh-theme
Just remove %m to remove and also you can remove the username too.
Once done,
Just run
#zsh
To reflect the changes, Enjoy :)
Thanks to Wes Bos' amazing video series Command Line Power User , I managed to find the answer.. It's pretty simple. Stuff like that is set in the ZSH theme.
Open up .zshrc, change the theme from ZSH_THEME="agnoster" (which is what I was using) to something else.
Wes Bos has made a lovely theme called Cobalt2 which does exactly what I was looking for :)
I've now changed it to ZSH_THEME="cobalt2"
All,
When JlinkSTR91x.exe is invoked, it opens up a command prompt J-Link. In this prompt, we can type the commands. I need to do the same using AutoIt scripting.
This is what I tried,
;Execution.au3
Local $foo = Run("C:\\Program Files\\SEGGER\\JLinkARM_V426b\\JLinkSTR91x.exe", "", #SW_SHOW, $STDIN_CHILD)
StdinWrite($foo,"setb 0")
ProcessWaitClose($foo)
When I run this script, J-Link prompt opens up but unable to send the command "setb 0" at this prompt. Please help.
Run("cmd")
$prog = WinWaitActive("C:\WINDOWS\system32\cmd.exe")
ControlSend($prog, Default, $prog, "exit")
Sleep(999)
ControlSend($prog, Default, $prog, "{Enter}")
WinWaitClose($prog)
This does theoretically what you want. Just replace the cmd with your command and insert the actual title of the prompt.You can find it out with the Info-Tool included with AutoIt.
It's just a working example.
And it will even send the text when your prompt isn't active any more. You can even hide your prompt with WinSetState($prog, Default, #SW_HIDE) .
When I search in, for example, man ls while in a tmux session, the search strings don't appear highlighted - the page jumps down so that the search string is on the top line of the buffer, as expected, but it's not highlighted.
Doing the same thing in the same shell while not in a tmux session results in highlighted search strings.
I have no idea where to start looking to solve this. Any hints are appreciated.
Based on Less Colors For Man Pages by Gen2ly, here is my man page and how to do it:
Preview
This is a shell, not a web page !
How to
(optional) I'm using Tomorrow theme for Konsole/Yakuake ;
Edit your ~/.bashrc ~/.zshrc, etc. to add :
# Colored man pages: http://linuxtidbits.wordpress.com/2009/03/23/less-colors-for-man-pages/
# Less Colors for Man Pages
export LESS_TERMCAP_mb=$'\E[01;31m' # begin blinking
export LESS_TERMCAP_md=$'\E[01;38;5;74m' # begin bold
export LESS_TERMCAP_me=$'\E[0m' # end mode
export LESS_TERMCAP_se=$'\E[0m' # end standout-mode
export LESS_TERMCAP_so=$'\E[38;5;016m\E[48;5;220m' # begin standout-mode - info box
export LESS_TERMCAP_ue=$'\E[0m' # end underline
export LESS_TERMCAP_us=$'\E[04;38;5;146m' # begin underline
Reload your config and try a man page search :
. ~/.bashrc && man ls
Fixed it. The problem is to do with the way that the screen $TERM handles italics. From the tmux FAQ:
vim displays reverse video instead of italics, while less displays italics
(or just regular text) instead of reverse. What's wrong?
This matches my problem exactly. The $PAGER used by man is less by default - basically, man uses less to show the contents of the manual pages. In my case, less wasn't highlighting text, just showing regular text.
The reason for this happening:
Screen's terminfo description lacks italics mode and has standout mode in its
place, but using the same escape sequence that urxvt uses for italics. This
means applications (like vim) looking for italics will not find it and might
turn to reverse in its place, while applications (like less) asking for
standout will end up with italics instead of reverse.
The solution is to make a new terminfo file for tmux, which lets it know that italics are supported. The solution's outlined in the (at time of writing) very, very bottom of the tmux FAQ.
After creating the new terminfo file, in tmux: C-b :source-file /absolute/path/to/.tmux.conf (from this SuperUser question) - this should make tmux reload the .tmux.conf file. However, this didn't work for me, and the changes only applied after restarting the tmux server (close all tmux sessions, then re-open them).
This thread is a few years old but is still the one that comes up as the best search result, so I'm answering with what finally worked for me. This is based off of tmux FAQ.
...but the instructions aren't completely clear on when or where to substitute the -256color string. I use gnome-terminal (v 3.16.2) with tmux, and this worked for me:
$ mkdir $HOME/.terminfo/
$ screen_terminfo="screen-256color"
$ infocmp "$screen_terminfo" | sed \
-e 's/^screen[^|]*|[^,]*,/screen-256color|screen with italics support,/' \
-e 's/%?%p1%t;3%/%?%p1%t;7%/' \
-e 's/smso=[^,]*,/smso=\\E[7m,/' \
-e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
-e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/screen.terminfo
$ tic /tmp/screen.terminfo
And tell tmux to use it in ~/.tmux.conf:
set -g default-terminal "screen-256color"
Note: I tried it once without the -256color and since that didn't work (still seeing italics instead of highlighting), I had to delete everything under the .terminfo dir (another dir called 's') before the infocmp would work.
