Title: locate doesn´t seem to include home directory
Post by: Rosika on January 25, 2023, 09:27:58 AM

Hi all,  :)

I just stumbled over some curious behaviour. The "locate" command doesn´t seem to include my home directory.

On my desktop I created a text-file "prov.txt", then ran "sudo updatedb" but
"locate prov.txt" didn´t return any results.  :023:

The "find" command however doesn´t have any difficulties finding it.
Is it possible that the home directory is excluded by "locate"?

Many thanks in advance and many greetings.

Does it report older files in your home directory by any chance ?
If so check the date/time on the file in

Code: [Select]

ls -al /var/lib/mlocate/

Thanks for your reply.

No. locate doesn´t seem to find anything in my home directory.
I still punched in your command but just got this:

Code: [Select]

ls -al /var/lib/mlocate/
ls: cannot access '/var/lib/mlocate/': No such file or directory
That´s weird...  :029:

Many greetings from Rosika  :wave

OK.  For me, locate does not exclude the home directory on my system, but can't find anything not in the database.

Try

Code: [Select]

locate --statistics
This should report your database location. Then check the date time on the file it is using.

Hi stevef:

So sorry. Can´t even do that:

Code: [Select]

locate --statistics
locate: unrecognized option '--statistics'

I dont´t know if it helps anything at all. I´ll give you the contents of updatedb.conf

Code: [Select]

cat /etc/updatedb.conf
PRUNE_BIND_MOUNTS="yes"
# PRUNENAMES=".git .bzr .hg .svn"
PRUNEPATHS="/tmp /var/spool /media /var/lib/os-prober /var/lib/ceph /home/.ecryptfs

You may have plocate in LL6.  What's date and time of the file plocate.db at

Code: [Select]

ls -al /var/lib/plocate/

Hi stevef,  :)

thanks for your help.

Yes, indeed LL 6.2 came with both installed:

Code: [Select]

dglob plocate; and dglob mlocate
plocate:amd64
mlocate:all
The output of the command you provided is:

Code: [Select]

ls -al /var/lib/plocate/
total 7000
drwxr-xr-x  2 root root       4096 Jan 25 16:20 .
drwxr-xr-x 80 root root       4096 Jan 19 17:41 ..
-rw-r--r--  1 root root        183 Feb 17  2022 CACHEDIR.TAG
-rw-r-----  1 root plocate 7142630 Jan 25 16:20 plocate.db
So date and time of plocate.db is:

Code: [Select]

Jan 25 16:20Well, I tried the command just yesterday...

Thanks again and many greetings

Rosika,

I'm not helping much.  On the systems I have, mlocate (LL5) and plocate (LL6) both find files in the home directory (and any sub-directories) - subject to them being cached in the database.  Is your disk btrfs ?

I found this which suggest some issues with mlocate and btrfs related to home directory

Hi stevef,  :)

thanks for the link.
In fact I stumbled over the same article yesterday but didn´t bother referring to it as it doesn´t seem to apply with my case.

To answer your question:

No, the files system for my LL installation is ext3 for root as well as for home.
So I think changing the respective line to

Code: [Select]

PRUNE_BIND_MOUNTS = "no"wouldn´t be of help here.  :023:

Curious though: the locate command does find files elsewhere. So generally it works alright. It´s just the home partition which seems to be excluded.

Thanks anyway for your time and help.

Many greetings
