OpenCD is a directory changer. It will change your current directory to the specified partial or complete directory name. The directory is changed to the best matching directory name found, regardless of the directory depth. It also features cyclic directory changing via multiple calls of OCD. For speed purposes, OpenCD uses its own database of directories which has to be updated by the user with a command-line switch.
Npasswd is a replacement for the passwd command for UNIX. It subjects user passwords to stringent guessability checks to decrease the chance of users choosing vulnerable passwords. It addresses other deficiencies found of standard password change programs. Npasswd is designed to replace the programs passwd, chfn and chsh.
