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


Actually yes they will. Did you actually try the above? I did.

Ummm, yah I did try them both using a number of test scenarios but all tests failed. That's why I posted. However, I had been using my Win98SE system for about 5 hours when I did the tests.

This morning I cold restarted my system and tried to verify yesterday's results. Now I can't get any of my tests to fail and I have not installed or updated any software.

That's the last time I report an alleged problem without verifying it after a cold restart!

Sorry for the noise.
