pludi is correct, determining MD5 salt could be based on several things, timestamp that the user was created, last password change, you name it. Determining password is a pain in the butt, you could get some crack utilities like John the Ripper. But if you are the sysadmin of the box, reset the password, or force a password change for the end user.
Being security conscious I don't want a file laying around with passwords in an unencrypted format.. Get a trojan horse have that file stolen and kiss your career goodbye.

NAME
chpasswd - change user passwords in batch
SYNOPSIS
chpasswd [-D binddn] [-P path] [-c des|md5|blowfish | -e] [file]
DESCRIPTION
chpasswd changes passwords for user accounts in batch. It reads a list of login and password pairs from standard input or a file and uses
this information to update the passwords of this user accounts. The named account must exist and the password age will be updated. Each
input line is of the format:
user_name:password
If the hash algorithmus is not given on the commandline, the value of GROUP_CRYPT or, if not specified, CRYPT from /etc/default/passwd is
used as hash algorithmus. If not configured, the traditinal des algorithmus is used.
OPTIONS
-c des|md5|blowfish
This option specifies the hash algorithmus, which should be used to encrypt the passwords.
-e The passwords are expected to be in encrypted form. Normally the passwords are expected to be cleartext.
-D, --binddn binddn
Use the Distinguished Name binddn to bind to the LDAP directory. The user will be prompted for a password for simple authentica-
tion.
-P, --path path
The passwd and shadow files are located below the specified directory path. chpasswd will use this files, not /etc/passwd and
/etc/shadow.
FILES
/etc/default/passwd - default values for password hash
