I want to setup an alias alias open=xdg-open this whould replace the normal linux open command which in turn itself is a symlink to openvt.
我想设置一个别名别名open = xdg-open这可以替换普通的linux open命令,而open命令本身就是openvt的符号链接。

Yes it is. Once you alias it, it's valid only for your user.
是的。一旦您使用别名,它仅对您的用户有效。
You cold also add it inside ~/.bashrc, so it will be available only for your user and only for the current shell session (aliasing itself again every time you start a new session).
您也可以将其添加到〜/ .bashrc中,因此它仅适用于您的用户,并且仅适用于当前的shell会话(每次启动新会话时都会再次出现别名)。
In some distro, .bashrc loads a file called .bash_aliases for every session. You could also add your alias there.
在某些发行版中,.bashrc为每个会话加载一个名为.bash_aliases的文件。你也可以在那里添加你的别名。

alias is simply a text replacement for the original(like preprocessor in C).
别名只是原始文本的替换(如C中的预处理程序)。
It's valid only in the current shell where it was created it unless you add it to .rc file or .profile. Once you exit, the alias is no longer there and as such I don't see why it would cause any problem.
除非您将其添加到.rc文件或.profile,否则它仅在创建它的当前shell中有效。退出后,别名不再存在,因此我不明白为什么会导致任何问题。
