Bash defeated?

fopetesl · 04-16-2010, 06:04 AM

Ubuntu Breezy 5.10 (don't suggest an upgrade - it works!)

I'm trying to set up a script which updates some software on the hard drive from a directory on a USB Flash drive.

After I've plugged in the USB drive and seen it recognised by automount:

Code:

ls -l /vol/USBDISKB

OK - shows me the directory and files.

_BUT_

Code:

#!/bin/bash
 if [ -d /vol/USBDISKB ]; then
   echo "Found USB drive"
 else
   echo "Not found: USB drive!"
 fi

doesn't see the USB drive.

P.S. I also posted in LinuxExchange - maybe other gurus there

Try [ -b /vol/USBDISKB ]

Hi,

I think cola's intention is to check the permissions of /vol/USBDISKB. To also display the permissions of /vol

Code:

ls -al /vol

[EDIT]
Is this a script you just wrote or has it been working in the past?

I just tested a similar script on my machine and being fedora, it mounts the disk as owned by me.

Works perfectly with your settings.

Of course it gets mounted on media/usbdisk on fedora.

Is there a directory on the usbdisk you can check for instead of just the root directory ?

I aready tried that with

Code:

#!/bin/bash
if [ -e /vol/USBDISK/UPDATES/process.php ]; then
 echo "Found the file!"
else
 echo "Not found: process.php!"
fi

with same result.

permissions on almost all files and directories on the USB drive are 775 with root:users or root:root. That includes simply /vol
I already tried the same logged in as as root

Script has never succeeded. Is new code.

It would help if you posted the output of /bin/ls -l /vol as requested and the output of df -hT too.

ls -l /vol Difficult to do. Computer has no internet interface that works.

df -hT shows only hda1 & tmpfs.

Then the file system on the USB device is not mounted and ls -l /vol/USBDISKB is showing you files-and-directories on hda1 ???

No. ls -l /vol/USBDISKB shows me the files and directories on the USB drive.

Have used cp -f /vol/USBDISKB/process.php . for years to manually transfer data.

Just want to do it automagically.

OK. Right now I do not understand how the file system on the USB drive has been mounted but the mount is not shown by the df command. The symptoms you have reported are unusual so we are looking for something unusual here ...

Note I said "automount" in my original post.
OK, could be confusing but it's listed when I do a ps -A | grep auto* as automount and uses a (text) file /etc/auto.vol which has instructions where to mount devices as and when they are connected.

AFAIK autofs isn't used here.

When I dabbled with automount and it automounted file systems they were listed by df. Could it be that the automounting is not working? Can you post the content of /etc/auto.master and the /etc/auto.* files listed in it, presumably including (maybe only) /etc/auto.vol?
