How to fix incorrect Cygwin permission in Windows 7

Cygwin started to behave quite strangely after recent updates. I was not able to edit files in vim, because it was complaining that files are read only. Even cp -r didn’t work correctly. Permission of new directory was broken and I was not able to remove it. Pretty weird behavior.

E.g. ls -l

total 2
----------+ 1 georgik None 34 Jul 14 18:09 index.jade
----------+ 1 georgik None 109 Jul 14 17:40 layout.jade

Hm. It is clear that something is wrong with permission. Even owner has no permission on those files.

Output of mount command:

C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)

I found a solution at cygwin forum. It’s quite easy to fix it.

Open /etc/fstab and enter following line:

none /cygdrive cygdrive binary,noacl,posix=0,user 0 0

Save it. Close all cygwin terminals and start new terminal.

Output of mount:

C: on /cygdrive/c type ntfs (binary,noacl,posix=0,user,noumount,auto)

Output of ls -l
