Linux equivalent of -local option in find statement

Raynald Boucher — Thu, 10 Jan 2008 14:34:40 GMT

Hello all,
The "find . -local ..." statement restricted the search to the local machine under HP-UX Unix.

I have a script I want to migrate to a Fedora Core 5 box that uses this option and can't get it to work.
The Linux box has 3 nfs and one samba share filestems on it.

I tried using "find . ! -fstype nfs -a ! fstyep smb -name xxxxx" but the samba share is still searched. How can I search only the local machine without searching each local file system in turn?

[root@stealthdell root]# df

Shalom,

NFS and Samba are somewhat integrated.

You are using the right statement, but may need to update your syestem with bug fixes.

Try find -fstype ext3

Try "smbfs" instead of "smb" as your fstype.

2 good suggestions.
unfortunately neither works.

I tried "-fstype ext3" first and it still grabs floppy, cdrom and nfs as per the following.

I then tried the "not nfs and not smbfs" with identical results. I also tried using parenthesese to group the fstype options but that faile syntax.

Any other suggestions?

[root@stealthdell bin]# find / -fstype ext3 -name '*8.txt'

/usr/share/doc/vim-common-6.0/doc/usr_28.txt

... and so on

Thinking about it, find will probably still crawl the mount points, it's just that none of the files will match. Something like this will probably work, but it seems a little ugly....

find $(mount -t ext3 | cut -f3 -d' ') -xdev ...

Or you could marry something with '-mount'.

Also, newer Linux boxen don't use 'smbfs' any more, they use 'cifs'. That being said, showing us the output of a 'mount' command would help in that regard.

Here is the output from mount:

/dev/hda5 on /usr type ext3 (rw)

//persephone/vol1 on /home/prodsupp/apollo type smbfs (0)
[boucherr@stealthdell boucherr]$

I tried "find `grep ext3 /etc/fstab | awk '{print $2}'` -mount" and it looks like it's working.

Just another question:
How do I prevent find from following links?

It doesn't by default. You have to put '-follow' to make it show the linked files instead of the symbolic link.
