|
|
and
|
|
\fI/etc/shadow\fR
|

are checked to see that the entry has the proper format and valid data in each field. The user is prompted to delete entries that are improperly formatted or which have other uncorrectable errors.

The checks for correct number of fields and unique user name are fatal. If the entry has the wrong number of fields, the user will be prompted to delete the entire line. If the user does not answer affirmatively, all further checks are bypassed. An entry with a duplicated user name is prompted for deletion, but the remaining checks will still be made. All other errors are warning and the user is encouraged to run the
|
|
\fBusermod\fR
|
|
command to correct the error.

The commands which operate on the

|

\fBpwck\fR

should be used in those circumstances to remove the offending entry.
