After switching to using .bashrc instead of .bash_profile (I didn't like how the default terminal worked with one config file and utilities like screen with another), the behavior of iterm2 changed. Before, when I set the tab titles manually, they would remain there unless I ssh'd into another server, at which point the title would change to username@otherservername: /location/in/other/servers/filesystem. Now, when I change the tab titles, they remain so until the first command I execute in that tab. As soon as I run something, the tab title switches to myusername@mymacname: /my/location/in/my/mac/filesystem.

Using the command line argument, echo -ne "\e]1;tab title\a" doesn't help. It does switch (Slow enough to notice the title change on the screen), but when the command exits, the title is back where it used to be: myusername@mymacname: /my/location/in/my/mac/filesystem.

Ideally, I would like the tab titles to NEVER switch automatically, including when I ssh into another server. If that's not possible, I'd like to return to the previous behavior: as long as I'm on the local machine, keep the tab titles I set. Can that be done?

Here's my .bashrc file:

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# don't put duplicate lines in the history. See bash(1) for more options
# don't overwrite GNU Midnight Commander's setting of `ignorespace'.
export HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
# ... or force ignoredups and ignorespace
export HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)
fi

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
    xterm-color) color_prompt=yes;;
esac

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
    # We have color support; assume it's compliant with Ecma-48
    # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
    # a case would tend to support setf rather than setaf.)
    color_prompt=yes
    else
    color_prompt=
    fi
fi

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;36m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\$ '

    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '

# See /usr/share/doc/bash-doc/examples in the bash-doc package.

#if [ -f ~/.bash_aliases ]; then
#    . ~/.bash_aliases
#fi

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    eval "`dircolors -b`"
    alias ls='ls --color=auto -hF'
    #alias dir='dir --color=auto'

Found (partially) an answer. If this portion is commented out:

# 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"
    ;;
*)
    ;;
esac

i.e.:

# 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"
#    ;;
#*)
#    ;;
#esac

The tab titles are preserved as long as you're on the local machine. The server still changes them.

Look into the remote machine's default PS1: Enter echo $PS1 on the command line to view it, enter PS1='\$' to set it to a minimal value for testing whether that setting is responsible for changing your window title. –  Daniel Beck Nov 10 '11 at 20:34

Make sure $PROMPT_COMMAND is not set by running

echo $PROMPT_COMMAND

If the output is non-empty, that script is executed just before a prompt is displayed by the shell.


On OS X Lion, the default value is update_terminal_cwd, and it looks like this:

$ type update_terminal_cwd
update_terminal_cwd is a function
update_terminal_cwd () 
{ 
    local SEARCH=' ';
    local REPLACE='%20';
    local PWD_URL="file://$HOSTNAME${PWD//$SEARCH/$REPLACE}";
    printf '\e]7;%s\a' "$PWD_URL"
}

It is used to add the current working directory to Terminal's title bar.
