如何查找用户的文件和目录，并排除NFS挂载的NFS挂载和符号链接？

Question

I would like to find and change user account and it's default group on local File Systems but exclude massive NFS mounts and symbolic links to those mounts. I had tried multiple syntaxes but did not succeed -

find / -user dummyadm -print \( -fstype nfs -o type l \) -prune 

Please help!

It sounds like you're looking for the -xdev option, or its synonym -mount . This causes find to avoid crossing from one filesystem to another. The symbolic links should not be an issue in any case, because find 's default behavior is to not traverse symbolic links. This probably means you'll need to name all the filesystem roots you want to traverse, however. For example, if both /home and /tmp are on separate (local) filesystems, then you might do

find / /home /tmp -xdev -user dummyadm ...

Alternatively, if you want to use the -fstype test, then you should probably combine it with -not instead of trying to use -prune with it:

find / -user dummyadm -not -fstype nfs ...
