Like I said before, make sure you only change the passwords of "real" users and not of system related accounts.

Hopefully your "real" users are assigned a specific range for the uid (field 3 in /etc/passwd) and no other accounts have an uid within this range.

Now lets assume the uid of a "real" user is between 5000 and 7000.

Then the following script might do the job for you. The script assumes that "expect" is available on your system. You might have to replace "nawk" by "awk".

Code:
#!/usr/bin/ksh

for USER in `nawk 'BEGIN { FS=":" } { if ($3 >= 5000 && $3 <= 7000) print $1 }' /etc/passwd`
do
  expect -c "
    spawn passwd ${USER}
    expect \"New Password: \"
    send \"${USER}99\r\"
    expect \"Re-enter new Password: \"
    send  \"${USER}99\r\"
    expect eof" > /dev/null 2>&1
done

openssl_passwd

PASSWD(1)							      OpenSSL								 PASSWD(1)

NAME

       passwd - compute password hashes

LIBRARY

       libcrypto, -lcrypto

SYNOPSIS

       openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] {password}

DESCRIPTION

       The passwd command computes the hash of a password typed at run-time or the hash of each password in a list.  The password list is taken
       from the named file for option -in file, from stdin for option -stdin, or from the command line, or from the terminal otherwise.  The Unix
       standard algorithm crypt and the MD5-based BSD password algorithm 1 and its Apache variant apr1 are available.

OPTIONS

       -crypt
	   Use the crypt algorithm (default).

       -1  Use the MD5 based BSD password algorithm 1.

       -apr1
	   Use the apr1 algorithm (Apache variant of the BSD algorithm).

       -salt string
	   Use the specified salt.  When reading a password from the terminal, this implies -noverify.

       -in file
	   Read passwords from file.

       -stdin
	   Read passwords from stdin.

       -noverify
	   Don't verify when reading a password from the terminal.

       -quiet
	   Don't output warnings when passwords given at the command line are truncated.

       -table
	   In the output list, prepend the cleartext password and a TAB character to each password hash.

EXAMPLES

       openssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.

       openssl passwd -1 -salt xxxxxxxx password prints $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..

       openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
