> Cygwin these days seems to have a behaviour that confuses me regarding the > case of a disk name: >> ln -s "/cygdrive/c/Program Files" pf1 >> ln -s "/cygdrive/C/Program Files" pf2 >> ls -l pf* > lrwxrwxrwx 1 acn1 None 25 Jun 12 07:37 pf1 -> /cygdrive/c/Program Files > lrwxrwxrwx 1 acn1 None 20 Jun 12 07:37 pf2 -> /mnt/C/Program Files >> cygpath -ma ./pf1 > C:/cygwin64/home/acn1/pf1 > You see from the above that when I use cygpath to convert from a cygwin > name the drive letter C: is returned in upper case.
