I'm trying to edit /etc/hosts using Vi in Cygwin but it's read only. Is there a command similar to sudo? How do I edit a read-only file?

Try doing a forced overwrite. Instead of :wq to write and quit, try: :wq! to force write and quit.

Try using the Windows runas command then? runas /user:Administrator vi /etc/hosts – Majenko Mar 20 '11 at 17:59
Running cygwin as administrator allowed me to edit the file. Thanks for your help – Nope Mar 20 '11 at 18:05

Opening your cygwin shell as Administrator will grant your user root access. Then the files will no longer be readonly.
