Each line is of the format: + + + group_name:password + + + By default the supplied password must be in clear-text, and is + encrypted by chgpasswd. + + + The default encryption algorithm can be defined for the system with + the variable of /etc/login.defs, + and can be overwritten with the , + , or options. + + + This command is intended to be used in a large system environment + where many accounts are created at a single time. + + + + + OPTIONS + + The options which apply to the chgpasswd command + are: + + + + , + + Use the specified method to encrypt the passwords. + + The available methods are DES, MD5, and NONE. + + + The available methods are DES, MD5, NONE, and SHA256 or SHA512 + if your libc support these methods. + + + + + , + + Supplied passwords are in encrypted form. + + + + , + + Display help message and exit. + + + + , + + + Use MD5 encryption instead of DES when the supplied passwords are + not encrypted. + + + + + + ,  CHROOT_DIR + + + + Apply changes in the CHROOT_DIR + directory and use the configuration files from the + CHROOT_DIR directory. + Only absolute paths are supported. + + + + + , + + + Use the specified number of rounds to encrypt the passwords. + + + The value 0 means that the system will choose the default + number of rounds for the crypt method (5000). + + + A minimal value of 1000 and a maximal value of 999,999,999 + will be enforced. + + + You can only use this option with the SHA256 or SHA512 + crypt method. + + + By default, the number of rounds is defined by the + SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS variables in + /etc/login.defs. + + + + + + + + CAVEATS + + Remember to set permissions or umask to prevent readability of + unencrypted files by other users. + + + You should make sure the passwords and the encryption method respect + the system's password policy. + + + + + CONFIGURATION + + The following configuration variables in + /etc/login.defs change the behavior of this + tool: + + + &ENCRYPT_METHOD; + &MAX_MEMBERS_PER_GROUP; + &MD5_CRYPT_ENAB; + &SHA_CRYPT_MIN_ROUNDS; + + + + + FILES + + + /etc/group + + Group account information. + + + + /etc/gshadow + + Secure group account information. + + + + /etc/login.defs + + Shadow password suite configuration. + + + + + + + SEE ALSO + + + gpasswd1 + , + + groupadd8 + , + + login.defs5 + . + + + -- cgit v1.2.3
