I'm trying to find a way to jump to the previous prompt in iTerm using tmux. Can I set a binding to search a unique phrase within my prompt?
So to expand on Yuriy's answer. Inside your terminal you can run the following commands:
tmux copy-mode ; tmux send -X search-backward 'Example'
That should put your current tmux pane into copy-mode and then initiate a search for 'Example'. Now instead of typing that every time we want to search we'll create a shell script(lets say /tmp/search.sh) and then a tmux binding to that script
Contents of /tmp/search.sh
#!/usr/bin/env bash
tmux copy-mode ; tmux send -X search-backward 'These'
make sure you make it executable with chmod +x /tmp/search.sh. At this point you can test that it works by simply calling the script from your tmux session. To add it as a binding you can something akin to the following to your ~/.tmux.conf file:
bind p run-shell "bash /tmp/search.sh"
Make sure you source refresh the configuration in your tmux session and your new binding should initiate the search.
The canonical way of doing this is write a bash script to issue the commands back to your tmux.
But I'd like to suggest a mod that allows way more flexible scripting: http://ershov.github.io/tmux/ (I'm the author)
Using this mod, your problem can be solved this way:
bind p copy-mode ";" tcl {
set s [copy-mode-screenline -ex [copy-mode-get-cx]]
cursor-up
send-keys "?" "\x15$s"
}
This will read the current line from the beginning up to the cursor position and search for the previous occurrence of it.
The key 'p' can be changed to your preference.

Specifically, I need to create a profile that by default will have a small pain displaying the clock, which can be triggered with C-b t. However, I couldn't find the way to do that.
In this GitHub issue comment, a Collaborator of the project said it could be defined like a regular command, but on my ZSH setup, it just didn't work, saying "zsh: Command not found: C-b".
Does anyone happen to know how I can achieve this?
Thanks!!!
windows:
- work:
panes:
- tmux clock-mode
- ipython
Below is what happens when typing tmux clock-mode inside tmux session:
current tmux client connect to tmux server
attach to current(or the most recently) session
since the -t argument is omitted, the currently active pane in the current window is used for the clock-mode command.
Checkout the session in $man tmux for more detail.
COMMANDS
This section contains a list of the commands supported by tmux. Most commands accept the optional -t argument with one of target-client, target-session
target-window, or target-pane. These specify the client, session, window or pane which a command should affect. target-client is the name of the pty(7)
file to which the client is connected, for example either of /dev/ttyp1 or ttyp1 for the client attached to /dev/ttyp1. If no client is specified, the
current client is chosen, if possible, or an error is reported. Clients may be listed with the list-clients command.
On my local machine I've got 3 node.js instances running simultaneously. Each has it's own pane in a tmux window called "servers". The problem is that it's not that easy to figure out which node is running in which pane, 'cause their logs are similar.
What I need is a title for every pane. As I got, tmux itself doesn't have the feature: it has only titles for windows and not for panes. Launching a separate tmux session inside every pane for every node.js instance looks like an overkill.
So is there some small program that launches a command, wrapping its output with a specified status bar?
This functionality has been added to tmux in this commit. It is not in version 2.2, but it looks like it will be in 2.3.
To enable it:
tmux set -g pane-border-status top
or if you prefer:
tmux set -g pane-border-status bottom
To set a custom text as your pane border status line you can make use of pane-border-format, e.g. like so:
tmux set -g pane-border-format "#{pane_index} #{pane_current_command}"
tmux does support per-pane titles, but it does not provide a per-pane location to display these titles.
You can set a pane’s title with the escape sequence ESC ]2; … ESC \ (e.g. see the section called Names and Titles in the tmux manpage). You could do this from the shell like this:
printf '\033]2;%s\033\\' 'title goes here'
Each pane’s title defaults to the system’s hostname. By default the active pane’s title is displayed on the right side of the tmux status line (the default global value of the session variable status-right is "#22T" %H:%M %d-%b-%y, which shows 22 characters of the pane’s title, the time, and the date).
So, as long as you are satisfied with being able to see the active pane’s title (i.e. willing to switch panes to see the title of an inactive pane), you can get by with the default functionality. Just send the appropriate title-setting escape sequence before starting the main command for each pane.
If you absolutely need a dedicated line to display some per-pane information, then nested tmux sessions may not be as much (unnecessary) “overkill” as you might first think.
In the general case, to provide an inviolate status line on some given terminal, you will need a full terminal (re)emulator that sits between the original terminal and a new terminal (one with one fewer lines). Such (re)emulation is needed to translate control sequences sent to the inner terminal and translate them for the original terminal. For example, to maintain a status line at the bottom of the outer terminal, the command
Move to the last line.
sent to the inner terminal must be become
Move to the next to last line.
when translated for and sent to the outer terminal. Likewise, an LF sent to the inner terminal must become
If the cursor is on the next to last line, then scroll this line and all the lines above it up one line, to provide a clear next-to-last line (protecting the status line on the last line).
Otherwise, send an LF.
in the outer terminal.
Programs like tmux and screen are just such terminal re-emulators. Sure, there is a lot of other functionality wrapped around the terminal emulator, but you would need a large chunk of terminal emulation code just to provide a reliable status line.
There is, however, a light-weight solution as long as
your programs (Node.js instances) have limited terminal interactions with the panes in which they are running (i.e. no cursor positioning), and
you do not resize the panes while your programs are running.
Like many terminal emulators, tmux supports a “set scrolling region” terminal control command in its panes. You could use this command to limit the scrolling region to the top (or bottom) N-1 lines of the terminal and write some sort of instance-identifying text into the non-scrolling line.
The restrictions (no cursor movement commands allowed, no resizing) are required because the program that is generating the output (e.g. a Node.js instance) has no idea that scrolling has been limited to a particular region. If the output-generating program happened to move the cursor outside of the scrolling region, then the output might become garbled. Likewise, the terminal emulator probably automatically resets the scrolling region when the terminal is resized (so the “non-scrolling line” will probably end up scrolling away).
I wrote a script that uses tput to generate the appropriate control sequences, write into the non-scrolling line, and run a program after moving the cursor into the scrolling region:
#!/bin/sh
# usage: no_scroll_line top|bottom 'non-scrolling line content' command to run with args
#
# Set up a non-scrolling line at the top (or the bottom) of the
# terminal, write the given text into it, then (in the scrolling
# region) run the given command with its arguments. When the
# command has finished, pause with a prompt and reset the
# scrolling region.
get_size() {
set -- $(stty size)
LINES=$1
COLUMNS=$2
}
set_nonscrolling_line() {
get_size
case "$1" in
t|to|top)
non_scroll_line=0
first_scrolling_line=1
scroll_region="1 $(($LINES - 1))"
;;
b|bo|bot|bott|botto|bottom)
first_scrolling_line=0
scroll_region="0 $(($LINES - 2))"
non_scroll_line="$(($LINES - 1))"
;;
*)
echo 'error: first argument must be "top" or "bottom"'
exit 1
;;
esac
clear
tput csr $scroll_region
tput cup "$non_scroll_line" 0
printf %s "$2"
tput cup "$first_scrolling_line" 0
}
reset_scrolling() {
get_size
clear
tput csr 0 $(($LINES - 1))
}
# Set up the scrolling region and write into the non-scrolling line
set_nonscrolling_line "$1" "$2"
shift 2
# Run something that writes into the scolling region
"$#"
ec=$?
# Reset the scrolling region
printf %s 'Press ENTER to reset scrolling (will clear screen)'
read a_line
reset_scrolling
exit "$ec"
You might use it like this:
tmux split-window '/path/to/no_scroll_line bottom "Node instance foo" node foo.js'
tmux split-window '/path/to/no_scroll_line bottom "Node instance bar" node bar.js'
tmux split-window '/path/to/no_scroll_line bottom "Node instance quux" node quux.js'
The script should also work outside of tmux as long as the terminal supports and publishes its csr and cup terminfo capabilities.
Since tmux 2.6 you can do:
$ tmux select-pane -t {pane} -T {title}
# Examples:
$ tmux select-pane -T title1 # Change title of current pane
$ tmux select-pane -t 1 -T title2 # Change title of pane 1 in current window
$ tmux select-pane -t 2.1 -T title3 # Change title of pane 1 in window 2
You can see title per pane in a status bar with:
$ tmux set pane-border-status bottom # For current window
$ tmux set -g pane-border-status bottom # For all windows
Disable status bar with:
$ tmux set pane-border-status off # For current window
$ tmux set -g pane-border-status off # For all windows
I am using tmux version 2.3, I think border style is not supported in previous versions.
this is what worked for me:
For each pane set the title:
printf '\033]2;My Pane Title\033\\'
Then:
tmux set -g pane-border-format "#{pane_index} #T"
A gif is worth a thousand words. (source)
tmux-xpanes is a tmux-based terminal divider, which supports
displaying title for each pane through the newly added -t option.
I'm working on the pane status bar for tmux - ticket.
My development branch can be found here on github:
https://github.com/jonathanslenders/tmux
Right now, this already adds a working rename-pane "title" command. There are still some bugs, and the API will improve. The idea is to create a status bar per pane, which can have some formatting, like the session status bar. Like the rest of tmux, everything should become scriptable, and customizable. When finished and stable, it will probably be included in the official tmux.
Yes there is such a command: tmux. Give your session a name and it will be displayed in an inner status bar:
TMUX=0 tmux new-session -s my-new-session
TL;DR
Append following configs to your tmux config file (in my case is ~/.tmux.conf.local)
# dispaly pane_current_path as the pane title
set -g pane-border-status top
set -g pane-border-format "#{pane_index} #{pane_current_path}"
then run:
tmux source-file ~/.tmux.con
enjoy it

This is not helpful in the short-term, but there is a feature request for per-pane titles in tmux: http://sourceforge.net/tracker/?func=detail&aid=3495916&group_id=200378&atid=973265#
In the meantime, as others mentioned, nesting tmux works decently.
Adding these three lines inside .tmux.conf worked and doesn't intervene with the pane_title variable managed by tmux
set -g pane-border-status top
set -g pane-border-format "#[fg=black, bg=green] #{pane_index} #{#custom_pane_title}"
bind < command-prompt -p "New Title: " -I "#{#custom_pane_title}" "set-option -p #custom_pane_title '%%'"
After adding these lines, source the .tmux.conf to reflect the changes
tmux source-file ~/.tmux.conf
Inside tmux pane, press Ctrl+B <, enter the title of your choice, and pane title will be set.
The rationale to use a different variable
Pane title can be set from multiple sources, and I wanted to avoid any interference with it.
tmux select-pane -T title1
using escape sequence characters `printf '\033]2;%s\033\' 'title goes here
ref: https://gist.github.com/ethagnawl/db27bba3c4cccdc30ade2a0c54f49723
All existing answers don't mention how to actually change the default title, but the solution is hidden over at https://unix.stackexchange.com/a/564690/28354, and, for example, on Android Termux tmux, you can change the default title of "localhost" to the model name instead, like so, from within a zsh shell:
tmux set-hook -g after-split-window "select-pane -T \"$(getprop ro.product.model)\""
tmux set-hook -g after-new-window "select-pane -T \"$(getprop ro.product.model)\""
tmux set-hook -g after-new-session "select-pane -T \"$(getprop ro.product.model)\""
This will change the "localhost" from bottom-right status bar next to the clock, because pane_title is what's used, which, in turn, defaults to the hostname:
% tmux show-options -g status-right
status-right "#{?window_bigger,[#{window_offset_x}#,#{window_offset_y}] ,}\"#{=21:pane_title}\" %H:%M %d-%b-%y"
[0] 0:zsh 1:zsh 2:zsh- 3:zsh* "Pixel 2 XL" 22:55 26-Sep-21
Additionally, it can be made to be displayed at the top of each pane, too:
tmux set -g pane-border-status top
The format is controlled by pane-border-format, and it defaults as follows:
% tmux show-options -g pane-border-format
pane-border-format "#{?pane_active,#[reverse],}#{pane_index}#[default] \"#{pane_title}\""
I am using a vpn service from certain server. I was given with a root account, and when I connect with a root account, the command line looks like below.
root#xa9g82:/etc/#
Then I used useradd to add an account called 'temp'
When I connected to the server with temp, then the command line only has a single character.
$
The user information is not shown, neither the path. Also, note that, in root's command line I can use tab to automatically complete the filename, however 'temp's command line inserts tab space, when I press tab. It is very inconvenient.
I am using Ubuntu 10.04. How can I resolve this issue?
I usually edit ~/.bashrc. Being root, you might want to change the system-wide preferences, at /etc/bash.bashrc. Personally, I changed some lines in ~/.bashrc to look like:-
# If this is an xterm set the title to user#host:dir
case "$TERM" in
xterm*|rxvt*)
## PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u#\h: \w\a\]$PS1" # default
PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\h: \W\a\]$PS1" # How I like it

use prompt to set the prompt.... (man prompt...)
it depends on what shell you run each one has it's own tricks, but you can make it looks as you wish.
BASH
TCSH
It is likely that the default shell for root is set to /bin/sh, which does not provide many of the features that you may used to if you use a shell like bash. To check if this is the case, run the following command:
cat /etc/passwd | grep ^root
The last component of the line that this command outputs will be your shell (which, as stated previously, I'm guessing is /bin/sh). If this is not the shell you want (it probably isn't), then edit /etc/passwd (using nano or whatever editor you're most comfortable with) and change your shell to something more palatable, like /bin/bash. After doing this, you'll need to log out and then log back in.
I use an emacs daemon to preserve my emacs session even if I have to reboot the machine that I run my X server on or if I want to access the same session from a different machine. This works very well but when restoring a session I'd quite like to just run "emacsclient --create-frame --no-wait" to connect to the daemon without opening a new file. It won't let me get away without specifying a filename.
I've tried using --eval to execute a function rather than open a file but the window just goes away when the evaluation is complete.
(Emacs 23.1 via backports on Debian GNU/Linux 5.0.)
From the help provided by emacsclient, you have a few options. First, is the one mentioned already which is emacsclient -c. That will try to create a frame associated with the emacs daemon. The advantage to this is that if DISPLAY is not set, then it will open emacs in the terminal.
Which brings us to the next best option (especially if you are logging in remotely): emacsclient -t which forces emacs to open up in terminal mode even if DISPLAY is set.
Also keep in mind that you can set the display from the command-line as well. I use this often when logging in remotely from VNC. The full command would be emacsclient -d DISPLAY -c
emacsclient -c works for me.
emacsclient -n -e "(make-frame)"
The -n flag means that the emacsclient doesn't wait, and the emacs instance doesn't destroy the frame.
If you are using emacs from the command line, you might also want to consider emacsclient -t
When working on a linx CShell u get the option to press the up / down arrows to select the last command/s typed or the Command Buffer. This even works on Windows.
However this is not functional when working on Solaris, to which i recently switched. I am guessing that the shell is also a CShell.
Please tell me what key combination is required to have this feature on Solaris ?
The default shell in Solaris has command history, but you can also use Bash instead, it's more user friendly. Just type 'bash' (no quotes) at the command line. You can also edit /etc/passwd to make bash your default shell.
The "official" default shell for Solaris is actually sh, the original Bourne shell (see Chapter 10 of the Advanced User Guide for Solaris for more info). If you'd like to change it to csh or tcsh—and you're not root (it's generally considered bad practice to use anything but sh as root's default)—just issue passwd -e /path/to/shell_of_your_choice <loginname>. I'm guessing this would probably look like passwd -e /bin/csh <loginname>, but you'd probably want to make sure it exists, first.
It may be that it's the Korn shell in which case try <ESC>k.
bash at least will allow you to switch modes with "set -o vi" or "set -o emacs".
Maybe you can use the !! command, to repeat the previous one.
Use "echo $SHELL" to see what your login shell is. If it's ksh or bash, try "set -o emacs". If that works, you'll be able to use ^P to go back a command. ^R lets you search for a command, ^F and ^B to move around within the command.
If you can´t change your default shell, or you just want to try out one that works, you can kick off any other shell from your command line. I recommend you tcsh, which will have good command line editing and history using the arrow keys. Type /bin/tcsh at your prompt to try it out. You can use the earlier responses to change your default shell if you like tcsh. Make sure your have the following in your $HOME/.cshrc file:
set filec
set history=1000 # or some other large number
set autologout=0 # if you are logging in remotely under your account.
I hope this helps.
You enable history temporarily if you use BASH by typing
HISTSIZE=1000
which will enable up and down keys and store 1000 commands. After termal disconnetion all history will be gone.
This works on solaris 10.
For permanent solution add these lines to ~/.bashrc
HISTSIZE=1000
HISTFILESIZE=1000
