如何从命令行设置活动 gnome 终端的标题？[复制]

  • 772

有没有办法从终端本身设置 gnome-terminal 标题，而无需右键单击选项卡。就像是：

active-terminal --title "Foo"

之前有一个相关问题的答案几乎可以让您这样做：如何更改 Gnome-Terminal 标题？但这并没有将 gnome-terminal 选项卡标题设置为仅窗口标题。

command-line

    以下将终端的标题设置为“新终端标题”：

    echo -en "\033]0;New terminal title\a"

    不过，您可能还必须首先更改环境变量 PS1，否则您的更改将不会显示，因为它会在每个命令后重置标题。Ubuntu 附带的默认 .bashrc 包含以下行：

    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"

    ... "\e]0;" 代码告诉它在标题和图标名称属性中将所有内容写入“\ a”。您需要将其删除并将其设置为类似这样（即没有 \e]0; 代码）：

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

    然后，您使用上述 echo 命令所做的任何更改都将更改终端标题。如果您要经常使用它，可以将它放入 ~/.bashrc 文件中的函数中：

    set_term_title(){
   echo -en "\033]0;$1\a"
}

    然后，您可以通过执行以下操作从命令行将标题设置为“小猫”：

    set_term_title kittens

    （您必须在编辑 .bashrc 后重新启动 bash，才能使您的更改生效）

  2. 函数声明并非在所有 shell 中都有效，因此另一种方法是声明一个别名，如下所示：

    alias cd    'cd \!*; echo -en "\033]0;`pwd`\a"'

    该命令尤其会导致标题更改为 pwd 是什么。

    当然你会想要在启动终端时初始化标题，所以不要忘记包含 gnome-terminal --title。

    我使用 perl 脚本来帮助我首先确定所有参数值，然后它调用一个新的终端，如下所示：

    my $cmd = "gnome-terminal $window_with_profile $geometry $zoom $working_directory $temp_argv $title &";
system($cmd);

    但是您要如何初始化这些值取决于您...

    如果您愿意，欢迎您使用以下代码并对其进行调整以供您个人使用：

        #!/usr/bin/perl
    #use strict;
    use Getopt::Long;

    my $progName = "term.pl";

    =head1 OBJECTIVE: open a gnome-terminal with a given path and a new background color

     #1# In order to use this script you first need to set up 10 different terminal profiles each named "theme1" - "theme10"
        Edit... profiles... new... theme1
        Each theme should use a different color scheme...

     The themes are later called with --window-with-profile=theme$int
     This script then selects the next one one to open based on the number saved in the ~/.term_theme_counter file.

     ### The argument "." opens the terminal with the same dir as you are currently in. 
         Without it, the terminal opens to "~". Use --working-directory=<DIR> for others. 
         Also, -dir=<DIR> has been added for convenience

     ### You can still pass additional gnome-terminal arguments like: --tab_with_profile etc into the command 

     ### Also see gnome-terminal --help 
            and gconf-editor and gconftool-2  --> /apps/gnome-terminal/profiles/ 
            for editing terminal props

      EXAMPLES:

      term.pl .
      term.pl /cadtools/tech/

  3. 在 Ubuntu 12.10（我不确定以前的版本）中，默认 .bashrc 中有以下行：

    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

    因此，要获得所需形式的标题，您只需编辑PS1此部分的值。例如，如果您想将标题作为当前目录的名称，只需 更改\u@\h: 为\w\W
