如何停止iterm标签标题的自动更改?


7

切换为using .bashrc而不是.bash_profile(我不喜欢默认终端如何使用一个配置文件以及实用程序像screen另一个配置文件一样)之后,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,否则它们将保留在该位置,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,它们保持不变,直到我在该选项卡中执行第一个命令为止。一旦运行某些命令,选项卡标题就会切换为myusername@mymacname: /my/location/in/my/mac/filesystem

使用命令行参数echo -ne "\e]1;tab title\a"无济于事。它确实会切换(足够慢,以至于在屏幕上显示标题更改),但是当命令退出时,标题又回到了以前的位置:myusername@mymacname: /my/location/in/my/mac/filesystem

理想情况下,我希望选项卡标题不要自动切换,包括当我ssh进入另一台服务器时。如果那不可能,我想回到以前的行为:只要我在本地计算机上,就保留我设置的标签标题。能做到吗

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

# ... or force ignoredups and ignorespace
export HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it

确保$PROMPT_COMMAND未通过运行设置

echo $PROMPT_COMMAND

如果输出为非空,则该脚本将在外壳程序显示提示之前执行。


在OS X Lion上,默认值为update_terminal_cwd,它看起来像这样:

$ 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"
}

用于将当前工作目录添加到终端的标题栏中。

为了防止ssh更改主机名称,通常会这样做

export TERM=vt100

在您使用ssh之前,请执行此操作,因为默认的初始化文件(bashrc等)会查看终端变量,并且仅在终端为xterm时才更改标题(如今已成为事实上的标准)。

注意:使用此技巧,您至少会丢失“备用屏幕”,颜色以及可能无法欣赏的其他精美终端功能。


我不仅可以最终使标签正确命名,而且不再需要unalias -a为避免出现颜色而开始每个ssh会话。

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

即:

# 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下来。服务器仍会更改它们。

查看远程计算机的默认设置PS1echo $PS1在命令行上输入以查看它,输入PS1='\$'以将其设置为最小值以测试该设置是否负责更改窗口标题。

感谢这里的所有人。我终于明白了我所需要的。

  1. 仅保留本地选项卡名称对我来说是没有用的,因为我专门将ssh放入盒子中。

  2. 我在终端中使用颜色,但我不想像Viljo的解决方案那样禁用颜色。

具体来说,我在本地计算机上运行了多个无聊的盒子,并且使其中的几个保持打开状态。我想轻松地将选项卡名称设置为vagrant框的OS版本,并保持这种状态。我把选项卡中打开很长一段时间,所以我不介意手动设置的名称,但它需要不被重置自动。

另外,由于这些无用的盒子,我不想更改它们的设置,如果以后我将不得不再次更改vagrant destroy

因此,我的发现:

在CentOS 6上,选项卡名称更新代码放置在中$PROMPTNAME。可以通过运行以下命令来中和它,并在一个命令中设置标签名:

PROMPT_COMMAND="" && printf '\e]1;%s\a' "CentOS 6.6"

在Ubuntu上,标签名更新代码直接位于$PS1; 中。它被预先设置为$PS1by的设置值~/.bashrc。可以通过运行以下命令来还原和设置选项卡名称:

PS1="${PS1##*\}}" && printf '\e]1;%s\a' "Ubuntu 14.04"
