如何從 /bin/bash 行中刪除路徑？

有沒有辦法隱藏 CLI 行中的路徑？

現在我明白了：

fresh_m2@bloedlvm:/srv/www/vhosts/$

我想要這樣：

fresh_m2@bloedlvm$

因為如果我深入文件夾，那麼游標已經在螢幕中間：

fresh_m2@bloedlvm:/srv/www/vhosts/fresh_m2/vendor/magento/framework/Model/ActionValidator/RemoveAction$

路徑已經顯示在膩子的頂部，這對我來說已經足夠了：

在.bashrc您發布的文章中，刪除標誌\w前帶有 PS1 的行。$根據您的需要，請務必在if [ "$color_prompt" = yes ]; then. 如果你想同時刪除它，你可以使用這個：

前：

if [ "$color_prompt" = yes ]; then
   PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
   PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

後：

if [ "$color_prompt" = yes ]; then
   PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]\$ '
else
   PS1='${debian_chroot:+($debian_chroot)}\u@\h\$ '
fi

注意：更改僅在下一個會話中生效。

\w注意：我還從第一個 PS1 變數中刪除了冒號和顏色程式碼。

（見bash man，在標題“提示”下描述了轉義序列）
