File::Find options to ignore NFS mounts

hrisheekesh_kale has asked for the wisdom of the Perl Monks concerning the following question:

Hi All, I have written a script to scan entire linux filesystem using File::Find. However, the filesystem has NFS mounts and the find module traverses the NFS mount as well and therefore takes hours to complete. Can you help me with a way of specifying options for File::Find that will ignore NFS mounts so that scanning completes much faster. I am not interested in scanning NFS filesystem. On a linux system we would typically do this using the following find options - $ -fstype nfs -o -fstype autofs $ -prune I am looking for similar options in perl.

See the `$File::Find::prune` variable (in File::Find) and the documentation below it, which also lists the `nfs` case of your problem.	[reply] [d/l] [select]

Hi hrisheekesh_kale, See Restrict file search within current filessystem using wanted subroutine for how to restrict File::Find to the filesystem(s) on which the search began. You can also implement your own logic and use the `$File::Find::topdev` variable in other ways, such as exclude certain filesystems from the search. To get the device number of a path, try this: `perl -le 'print +(stat("/tmp"))[0]'` Hope this helps, -- Hauke D	[reply] [d/l] [select]
