Fdisk and grep command not working in udev trigger
Hi Guys,
Can someone take a look at my scripts what missing, plugin usb drive the script is running can log all my echo but cannot execute command. Is there any configuration in linux or to my scripts need to add?.
What i want to achieve is every time I plugin the usbdisk automatic mount to /media/usb/test
Reload all rules in udev:
Trigger all udev rules:
Here the log ouput:
Looking at the output(mount /media/usb/test), DEVNAME is not set. It looks like the previous fdisk command is not returning anything. What is fdisk -l |grep FAT16 |awk '{print $1}' returning if you run it manually?
If DEVNAME isn't set, the mount command won't know which device to mount, and will look in the fstab / mtab for /media/usb/test to figure out what to do.

Supposedly it will return /dev/sdb1 in my case, already tried manually like this DEVNAME="/dev/sdb1" and put echo $DEVNAME and i see the output, but is not mounting
"Supposedly" doesn't really instil confidence You tried setting DEVNAME manually, and that also didn't work?
Is all of the code in the same script.. e.g. did you export DEVNAME if it's not?
If you set DEVNAME manually, after (or in place of) the fdisk command, there's no reason that the output would be
instead of
If the variable DEVNAME is not created as read-only (e.g. gives an error why you try to set it), and the script is not being run in a shell jail (chroot environment), that is.
I have made a program that reads a text file and checks for palindromic words and then outputs them. They each appear on a new line with a count of the number of occurences beside each of the words.
Requirements for being classed as palindrome are that the word must have at least 3 letters and... (7 Replies)
Hello,
MBR partition table made by linux fdisk looks certainly not correct when printed by openbsd fdisk:

I'm curious about the behavior where any udev labeled device causes that corresponding listing to disappear from fdisk, sfdisk, or in the case of RDAC, lsvdev.
I have seen this on both EMC clariion and Sun Storagetek/Engenio 6540 arrays.
