我需要从复制sample.txt到foo/粘贴bar/时bar/应该重命名为test.txt
我需要为此使用什么命令？
当我在我的 Linux 平台上安装 maven 3.5.4 时，我遇到了这个错误：
$ sudo export PATH=/usr/local/apache-maven-3.5.4/bin
Command 'sudo' is available in '/usr/bin/sudo'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
sudo: command not found
我也试过export PATH=/usr/local/apache-maven-3.5.4/bin了，但是没有用。
