我想知道是否有人可以帮助弄清楚为什么我的简单 bash 脚本不起作用，我不断收到：

The shell looks through the colon separated list of directories in PATH to find executables. Since you have used the name PATH to be the target destination, that is where it is looking for svn. Just choose a different name for the variable. That is, do not overwrite PATH.
shell 在 PATH 中查找以冒号分隔的目录列表以查找可执行文件。由于您使用名称 PATH 作为目标目的地，这就是它寻找 svn 的地方。只需为变量选择一个不同的名称。也就是说，不要覆盖 PATH。
