grpck - verify integrity of group files |

!!SYNOPSIS |

__grpck__ [[__-r__] [[''group shadow''] |

!!DESCRIPTION |
| |
|
21 |
|
| |
|
22 |
|
| |
|
23 |
__grpck__ verifies the integrity of the system |
| |
|
24 |
authentication information. All entries in the |
| |
|
25 |
''/etc/group'' and ''/etc/gshadow'' are checked to see |
| |
|
26 |
that the entry has the proper format and valid data in each |
| |
|
27 |
field. The user is prompted to delete entries that are |
| |
|
28 |
improperly formatted or which have other incorrectable |
| |
|
29 |
errors. |
| |
|
30 |
|
| |
|
31 |
|
| |
|
32 |
Checks are made to verify that each entry has |
| |
|
33 |
|
| |
|
34 |
|
| |
|
35 |
- the correct number of fields |
| |
|
36 |
- a unique group name |
| |
|
37 |
- a valid list of members and administrators |
| |
|
38 |
|
| |
|
39 |
|
| |
|
40 |
The checks for correct number of fields and unique group |
| |
|
41 |
name are fatal. If the entry has the wrong number of fields, |
| |
|
42 |
the user will be prompted to delete the entire line. If the |
| |
|
43 |
user does not answer affirmatively, all further checks are |
| |
|
44 |
bypassed. An entry with a duplicated group name is prompted |
| |
|
45 |
for deletion, but the remaining checks will still be made. |
| |
|
46 |
All other errors are warnings and the user is encouraged to |
| |
|
47 |
run the __groupmod__ command to correct the |
| |
|
48 |
error. |
| |
|
49 |
|
| |
|
50 |
|
| |
|
51 |
The commands which operate on the ''/etc/group'' file are |
| |
|
52 |
not able to alter corrupted or duplicated entries. |
| |
|
53 |
__grpck__ should be used in those circumstances to remove |
| |
|
54 |
the offending entry. |
| |
|
55 |
!!OPTIONS |

56 |
|

|
57 |
|
| |
|
58 |
By default, __grpck__ operates on the files |
| |
|
59 |
''/etc/group'' and ''/etc/gshadow''. The user may |
| |
|
60 |
select alternate files with the ''group'' and |
| |
|
61 |
''shadow'' parameters. Additionally, the user may execute |
| |
|
62 |
the command in read-only mode by specifying the __-r__ |
| |
|
63 |
flag. This causes all questions regarding changes to be |
| |
|
64 |
answered __no__ without user intervention. |
