有没有办法在终端内部设置 gnome-terminal 标题，而不必右键单击选项卡。例如：
active-terminal --title "Foo"
之前有一个相关问题，其答案几乎可以让你做到这一点：如何更改 Gnome-Terminal 标题？但这并没有设置 gnome-terminal 选项卡标题，只设置了窗口标题。
答案1
以下将终端的标题设置为“新终端标题”：
echo -en "\033]0;New terminal title\a"
您可能还需要更改环境变量 PS1，第一的但是，否则您的更改将不会显示，因为它会在每条命令后重置标题。Ubuntu 附带的默认 .bashrc 包含以下行：
PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
...“\e]0;”代码告诉它将所有内容写入 title 和 icon-name 属性中的“\a”之前。您需要将其删除并将其设置为类似以下内容（即没有 \e]0; 代码）：
PS1="${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，可以将其放入 ~/.bashrc 文件中的函数中：
set_term_title(){
echo -en "\033]0;$1\a"
}
然后您可以通过以下命令从命令行将标题设置为“小猫”：
set_term_title kittens
（编辑 .bashrc 后，你必须重新启动 bash，以使更改生效）
答案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别名，如下所示：
alias cd 'cd \!*; echo -en "\033]0;`pwd`\a"'
此命令特别会导致标题更改为密码。
当然，您会希望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);
但是如何初始化这些值取决于你……
如果您愿意，欢迎您采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 $progName = "term.pl";
=pod
=head1 OBJECTIVE: open a gnome-terminal with a given path and a new background color
#1# In order to use this script you first need to set up 10 different terminal profiles each named "theme1" - "theme10"
Edit... profiles... new... theme1
Each theme should use a different color scheme...
The themes are later called with --window-with-profile=theme$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

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

答案3
在 Ubuntu 12.10（我不确定以前的版本）中，默认的 .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，要获得您想要的标题形式，您只需编辑PS1此部分的值。例如，如果您希望将标题作为当前目录的名称，只需将其 更改\u@\h: 为\w\W
