see discussion on "-l" and "-u" command options in man passwd ...

new to unix? be familiar with the commands by listing the usual commands in /usr/bin, /bin, /usr/sbin, /sbin, and /etc then reading their man pages ... there may also be additional commands in other locations (i.e., /usr/local/bin, /opt/local/bin, etc.) depending on your server build ...
