如何将当前正在运行的进程名称放入GNOME终端选项卡标题(或只有一个选项卡时标题栏)?

尽管https://superuser.com/questions/42362/gnome-terminal-process-name-in-tab-title提供了一个解决方案(如下所示),但它在启动时会使每个选项卡完全混乱,从而显得破碎。还有更好的方法吗?

case "$TERM" in
xterm*|rxvt*)
    set -o functrace
    trap 'echo -ne "\e]0;$BASH_COMMAND\007"' DEBUG
    PS1="\e]0;\s\007$PS1"
    ;;
*)
    ;;
esac

好吧,因为每个人似乎都知道David Pashley的解决方案,所以我很惊讶我花了这么长时间才找到这个。 它实际上解决了bash-completion问题。

要明确:我自己在这里做了什么,但研究。所有功劳归功于Marius Gedminas(http://mg.pov.lt/blog/bash-prompt.html)。

这对我来说非常适合Gnome-Terminal / Terminator

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'

    # Show the currently running command in the terminal title:
    # http://www.davidpashley.com/articles/xterm-titles-with-bash.html
    show_command_in_title_bar()
    {
        case "$BASH_COMMAND" in
            *\033]0*)
                # The command is trying to set the title bar as well;
                # this is most likely the execution of $PROMPT_COMMAND.
                # In any case nested escapes confuse the terminal, so don't
                # output them.
                ;;
            *)
                echo -ne "\033]0;${USER}@${HOSTNAME}: ${BASH_COMMAND}\007"
                ;;
        esac
    }
    trap show_command_in_title_bar DEBUG
    ;;
*)
    ;;
esac
