如何停止自动更改 iterm 选项卡标题？

Question

在切换到使用.bashrc而不是.bash_profile（我不喜欢默认终端如何使用一个配置文件和实用程序screen与另一个一样）后，iterm2 的行为发生了变化。以前，当我手动设置选项卡标题时，除非我ssh进入另一台服务器，否则它们将保留在那里，此时标题将更改为username@otherservername: /location/in/other/servers/filesystem. 现在，当我更改选项卡标题时，它们将保持不变，直到我在该选项卡中执行的第一个命令。一旦我运行了一些东西，选项卡标题就会切换到myusername@mymacname: /my/location/in/my/mac/filesystem.

使用命令行参数echo -ne "\e]1;tab title\a"并没有帮助。它确实切换了（足够慢以注意到屏幕上的标题更改），但是当命令退出时，标题又回到了原来的位置：myusername@mymacname: /my/location/in/my/mac/filesystem。

理想情况下，我希望标签标题永远不会自动切换，包括当我ssh进入另一台服务器时。如果这不可能，我想回到以前的行为：只要我在本地机器上，就保留我设置的标签标题。可以做到吗？

这是我的 .bashrc 文件：

# ~/.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

Answer 1

转到 Iterm 的首选项 > 配置文件 > 终端

取消选中“终端可以设置选项卡/窗口标题”

现在您可以命名您的选项卡，SSH 进入服务器，退出并仍然保留原始选项卡名称。

Answer 2

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.

找到（部分）答案。如果这部分被注释掉：

# 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

IE：

# 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

只要您在本地计算机上，选项卡标题就会保留。服务器仍然改变它们。
