Proprietary Escape Codes

iTerm2 supports several non-standard escape codes. These may not work properly in tmux or screen, and may have unknown effects on other terminal emulators. Proceed with caution.

A quick comment on notation: in this document, ^[ means "Escape" (hex code 0x1b) and ^G means "bel" (hex code 0x07).

Set cursor shape


where N=0, 1, or 2.

  • 0: Block
  • 1: Vertical bar
  • 2: Underline

Add this to your .vimrc to change cursor shape in insert mode:

let &t_SI = "\<Esc>]50;CursorShape=1\x7"
let &t_EI = "\<Esc>]50;CursorShape=0\x7"

This is derived from Konsole.

Set Mark

The "Set Mark" (cmd-shift-M) command allows you to record a location and then jump back to it later (with cmd-shift-J). The following escape code has the same effect as that command:


Steal Focus

To bring iTerm2 to the foreground:


Clear Scrollback History

To erase the scrollback history:


Set curent directory

To inform iTerm2 of the current directory to help semantic history:


Post a Growl notification

To post a Growl notification:

^[]9;Message content goes here^G

This will have no effect if Growl is not running.

Change profile

To change the session's profile on the fly:


Copy to clipboard

To place text in the pasteboard:


Where name is one of "rule", "find", "font", or empty to mean the general pasteboard (which is what you normally want). After this is sent, all text received is placed in the pasteboard until this code comes in:


Set window title and tab chrome background color

To set the window title and tab color use this escape sequence:


Replace N with a decimal value in 0 to 255.

Example in bash that turns the background purple:

echo -e "\033]6;1;bg;red;brightness;255\a"
echo -e "\033]6;1;bg;green;brightness;0\a"
echo -e "\033]6;1;bg;blue;brightness;255\a"

To reset the window title and tab color, use this code:


For example:

echo -e "\033]6;1;bg;*;default\a"

Change the color palette


Replace "n" with:

  • 0-f (hex) = ansi color
  • g = foreground
  • h = background
  • i = bold color
  • j = selection color
  • k = selected text color
  • l = cursor
  • m = cursor text

rr, gg, bb are 2-digit hex value (for example, "ff"). Example in bash that changes the foreground color blue:

echo -e "\033]Pg4040ff\033\\"
