“gnome-terminal”的标题在 Ubuntu 中被 .bashrc 覆盖

一月

我需要同时打开大约 20 个终端并在每个终端上执行不同的命令,并且我还想用不同的名称命名每个窗口。

我正在使用如下内容:

gnome-terminal --title="some title goes here" -- bash -ic "ls; exec bash"

新窗口打开,显示标题some title goes here并在 1~2 秒后被覆盖并变成我正在运行命令的路径

 gnome-terminal --title="some title goes here" -- bash -ic "ls; exec bash"

从。

这是我的.bashrc

知道如何解决这个问题吗?

设置的提示PS1包含覆盖窗口标题的屏幕控制代码。

如果您不希望提示更改窗口标题,请取出执行此操作的代码段。

这是一个轻微的编辑,可让您no_title_change在调用 shell 中进行设置。这将替换您当前.bashrc;中的类似代码段。真正的改变是我们将变量更改$TERM为稍微复杂(并且有点hacky)的参数扩展

...

# If this is an xterm set the title to [email protected]:dir
# unless $no_title_change is set
case ${no_title_change-$TERM} in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\[email protected]\h: \w\a\]$PS1"
    ;;
*)
    ;;
esac

...

如果您无条件地想要删除标题更改逻辑,只需将此代码段替换为空即可。

为一组任务中的每个任务打开一个单独的终端窗口的用例是可疑的;更好的做法通常是将任务作为后台进程运行,每个进程都有输出到文件。然后您可以对整个场景进行自动化监控和日志记录,避免因不小心关闭错误的终端窗口而误终止进程等愚蠢问题;从多个位置远程管理流程变得可行。
