The cygpath program is a utility that converts Windows native filenames to Cygwin POSIX-style pathnames and vice versa.

The dumper utility can be used to create a core dump of running Windows process.

For each argument that is a regular file, special file or directory, getfacl displays the owner, the group, and the ACL. For each file given as parameter, setfacl will either replace its complete ACL (-s, -f), or it will add, modify, or delete ACL entries.

The regtool program allows shell scripts to access and modify the Windows registry.
