Good news.. It works this time..!!  ;D
Thank you Rich and curaga.

It took about 2 or 3 seconds to get mounted as can be seen in below debug.txt
Code: [Select]
+ sudo mkdir /tmp/theUSB
+ sync
+ drive=
+ '[' -z '' ']'
++ /sbin/blkid -lt LABEL=theLABEL -o device
+ drive=
+ sleep 1
+ '[' -z '' ']'
++ /sbin/blkid -lt LABEL=theLABEL -o device
+ drive=
+ sleep 1
+ '[' -z '' ']'
++ /sbin/blkid -lt LABEL=theLABEL -o device
+ drive=
+ sleep 1
+ '[' -z '' ']'
++ /sbin/blkid -lt LABEL=theLABEL -o device
+ drive=
+ sleep 1
+ '[' -z '' ']'
++ /sbin/blkid -lt LABEL=theLABEL -o device
+ drive=/dev/sdb1
+ sleep 1
+ '[' -z /dev/sdb1 ']'
+ sudo mount /dev/sdb1 /tmp/theUSB

However when I did "sleep 9" without the loop as above, it did not recognized.
Probably the USB drive needs to be probed a few times. Thus the loop "wakes" it up only in few seconds.

I'm not sure how how this works... But it does.
Thank you again guys...!!  :)

Sorry.. my bad.
Actually "sleep 9" is also working.
I put it at the wrong line... That's why it did not work.
Code: [Select]
sudo mkdir /tmp/theUSB
sudo mount -L theLABEL /tmp/theUSB
s l e e p 9

the correct one is
Code: [Select]
sudo mkdir /tmp/theUSB
s l e e p 9
sudo mount -L theLABEL /tmp/theUSB

even so.. I prefer Rich's loop code. That way I don't need to guess how long the "sleep" should be.

All good.. Mistery solved.
Sorry for the hassles guys..
And best of all, I learn more new tricks... Thank you!!  ;D ;D

Hi pek

It's also faster since it waits only until the label becomes visible.

The  sleep  command also can handle decimal numbers.
If you want to reduce the wait time a little more, try  sleep 0.25
