How to get slocate working

How to get slocate working

SalixLive-64

How can one get slocate working and by the same matter updatedb?

If I give the commands nothing happens as user one and as well as sudo.

I reinstalled with format ext3. It is really great now with no limits on persistent.

Does SalixLive64 not contain the file /etc/cron.daily/slocate?

In Salix64 14.2, this file contains:
Code: Select all
#!/bin/sh
ionice -c3 nice -n 19 /usr/bin/updatedb -c /etc/updatedb.conf

Where /usr/bin/updatedb is a symbolic link to slocate and /etc/updatedb.conf contains the following:
Code: Select all
# /etc/updatedb.conf:  slocate configuration file

PRUNEFS="devpts NFS nfs afs proc smbfs autofs iso9660 udf tmpfs cifs"
PRUNEPATHS="/dev /proc /sys /tmp /usr/tmp /var/tmp /afs /net /media /mnt"
export PRUNEFS
export PRUNEPATHS

Nothing doing :(

Entering the command it immediately goes back to command line
when normally it would take some time to updatedb.

The same is the case for "locate whatever". Immediately
back to command line and nothing located.

Yes westms, all those files and contents are there.

Here is the output of strace:

As I have mentioned in all previous posts

It does not work!

If it would work strace would show a lot of "dillo" locations.
It does not show a single one. And strace output would be much much longer.
What I posted is the entire output.

Portion of strace in Slint.
Code: Select all
sudo strace slocate dillo
....snip....
access("/home/guest", R_OK)             = 0
access("/home", R_OK)                   = 0
lstat64("/home/guest/.dillo/keysrc", {st_mode=S_IFREG|0644, st_size=2587, ...}) = 0
access("/home/guest/.dillo/keysrc", F_OK) = 0
access("/home/guest/.dillo", R_OK)      = 0
access("/home/guest", R_OK)             = 0
access("/home", R_OK)                   = 0

access("/home/guest/.dillo/dpid_comm_keys", F_OK) = 0
access("/home/guest/.dillo", R_OK)      = 0
access("/home/guest", R_OK)             = 0
access("/home", R_OK)                   = 0
lstat64("/home/guest/.dillo/bm.txt", {st_mode=S_IFREG|0600, st_size=9379, ...}) = 0
access("/home/guest/.dillo/bm.txt", F_OK) = 0
access("/home/guest/.dillo", R_OK)      = 0
....snip...


No such showing of dillo in strace of previous post;
since it does not work.

There is no updated db no matter how long I will wait after giving command since
no updating is taking place.

I am using slocate since more than 20 years in Linux so I know what I am doing one should assume. ;)

To compare with Salix64 14.2:

Is the database /var/lib/slocate/slocate.db renewed when you use the call
Code: Select all
sudo /usr/bin/updatedb -c /etc/updatedb.conf

? With me, yes.

Also the call
Code: Select all
sudo /usr/bin/updatedb -c /etc/updatedb.conf firefox

works. I do not have dillo.
The processes are done in silence. With me the database is renewed every time.

Then
Code: Select all
sudo slocate -c /etc/updatedb.conf

on the other hand does not produce anything.

Code: Select all
sudo slocate -c /etc/updatedb.conf firefox

throws out a lot of data, but does not change the database.

Called as
Code: Select all
sudo slocate -u -c /etc/updatedb.conf

or
Code: Select all
sudo slocate -u -c /etc/updatedb.conf firefox

the database is refreshed each time, also in silence.

The explanation for the difference between updatedb and slocate: When slocate is called as updatedb, the -u option is implied.

More than 20 years? Maybe you just got lost in an age-related memory gap as far as the use of the command is concerned? :)

Is this SalixLive64 installed on HDD/SSD or is it booted from a memory stick?
If the latter is true, are you sure /var/lib/slocate/slocate.db is changeable?

To run updatedb it takes usually several seconds to several minutes
to complete depending on the size of the partition.

For example in my Slint-64 it takes 125 sec.
In my Slackel-Openbox 35 sec.
In my Slackel-Live-Openbox 20 sec.

IN SALIXLlIVE-64 IT TAKES A FRACTION OF A SECOND
even so it is rather large. That is because it does not work AT ALL.

I am closing now this discussion since it does not seem to lead anywhere.
Thanks everyone!

And I wish westms that he will have my memory if he will ever reach my age.

Do you run it in RAM, without persistence?
If yes, to 100% sure run updatedb then try "slocate <name>", <name> being the name of a file of which you are sure that it exists.

EDIT. I think that updatedb just does not include in its database files in RAM. I just tried that on Slint:
Code: Select all
didier[/dev/shm/didier]$ su
root's Password:
root[/dev/shm/didier]# updatedb
root[/dev/shm/didier]# locate at-spi2-HA71AZ
root[/dev/shm/didier]# exit
didier[/dev/shm/didier]$ ls |grep at-spi2-HA71AZ
at-spi2-HA71AZ
didier[/dev/shm/didier]$ locate at-spi2-HA71AZ
didier[/dev/shm/didier]$ locate Musique
/home/nouveau/Musique
/home/didier/Musique
/old/home/didier/Musique
didier[/dev/shm/didier]$

As you can see locate finds files in mass storage device (like Musique) but not in RAM like at-spi2-HA71AZ, (dev/shm/didier is a temporary directory in shared memory).

No, I do no not run it RAM, have not enough memory.

There comes to mind could it be that memory is short
to run slocate?
Code: Select all
one[Desktop]$ free
                     total             used        free                shared  buff/cache   available
