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

Question

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 ，1~2 秒后它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 ：

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything

知道如何解决这个问题吗？

PS1中设置的提示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，可让您在调用 shell 中设置no_title_change 。 这将替换您当前.bashrc中的类似片段； 真正的改变是我们将变量$TERM更改为稍微复杂（并且有点 hacky）的参数扩展。

...

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