/usr/bin/passwd is the command. The files you're referring to are password databases. Its the passwd(1) command that writes into /etc/passwd, which has the required permissions to do so because of setuid.
Code:
$ ls -l /usr/bin/passwd -rwsr-xr-x 1 root root 28480 2007-02-27 13:23 /usr/bin/passwd $ file $_ /usr/bin/passwd: setuid ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.4.1, dynamically linked (uses shared libs), for GNU/Linux 2.4.1, stripped $ ls -l /etc/passwd -rw-r--r-- 1 root root 2324 2008-02-06 10:52 /etc/passwd $ file $_ /etc/passwd: ASCII text
