Is there a way to find out in a bash script the cygdrive prefix?
I thought something simple like
 mount -p|tail -1|cut -f1
but that incorrectly assumed the fields were tab delimited.
Since there can be spaces in the cygdrive prefix, I can't
use space a delimiter, example:
# mount -p
Prefix              Type         Flags
/cyg drive posix path  system       binmode

There may be a simpler way to do it, but this seems to work:


mount -p | sed -n '2s/\([^ ]\) *[^ ][^ ]* *[^ ][^ ]*$/\1/p'


This is shorter:

mount -p | sed -nr '2s/([^ ]) +\S+ +\S+$/\1/p'


Neither of which work if there is a space in the cygdrive prefix; viz a viz:


 Prefix              Type         Flags
/cyg drive posix path  system       binmode

However,

mount -p | sed -nr '2s/([^ ].*) +\S+ +\S+/\1/p'

does the trick.
