if [ -w branching: how to spot a locked USB stick
Fri Jul 13 06:04:00 GMT 2007
This question isn't strictly Cygwin, but I hope it's OK to ask it in the
context of Cygwin on a portable device eg a CD or a usb mobile drive or
memory stick: the bash command
if [ -w /h ] ; then echo +W ; else echo -W ; fi
tests a device located at /h (or /cygdrive/h) for write-ability: eg a
USB memory stick will echo +W and a CD will echo -W. If the stick is
locked, however, you still get +W. Does anybody know whether bash has
the capability to distinguish a locked stick from an unlocked stick,
(through "if [ ..", or by other means) please?
Even better, if it could be used to distinguish between write-enabled
and write-protected folders/ files.
