How do I determine if a directory is a mounted NFS mount point in shellscript
提问by AndrewR
I want to write a sh/bash script that can determine whether a particular directory is a mount point for an NFS filesystem.
我想编写一个 sh/bash 脚本来确定特定目录是否是 NFS 文件系统的挂载点。
eg something like
例如像
$ mkdir localdir
$ mkdir remotedir
$ mount host:/share ./remotedir
$ classify_dirs.sh
--> localdir is local
--> remotedir is an NFS mount point

This question is effectively a dup of how-can-i-tell-if-a-file-is-on-a-remote-filesystem-with-perl
这个问题实际上是一个重复的 how-can-i-tell-if-a-file-is-on-a-remote-filesystem-with-perl
The short answer is to use the statcommand
简短的回答是使用stat命令
eg
例如
$ stat -f -L -c %T localdir
ext2/ext3
$ stat -f -L -c %T remotedir
nfs
Then a directory is an NFS mount point if its type is 'nfs' and its parent directory isn't.
如果一个目录的类型是“nfs”而它的父目录不是，那么它就是一个 NFS 挂载点。
