39 | .Nd edit the password file | |
40 | .Sh SYNOPSIS | |
41 | .Nm vipw | |
42 | .Sh DESCRIPTION | |
43 | .Nm Vipw | |
44 | edits the password file after setting the appropriate locks, | |
45 | and does any necessary processing after the password file is unlocked. | |
46 | If the password file is already locked for editing by another user, | |
47 | .Nm vipw | |
48 | will ask you | |
49 | to try again later. The default editor for | |
50 | .Nm vipw | |
51 | is | |
52 | .Xr vi 1 . | |
53 | .Pp | |
54 | .Nm Vipw | |
55 | performs a number of consistency checks on the password entries, | |
56 | and will not allow a password file with a | |
57 | .Dq mangled | |
58 | entry to be | |
59 | installed. | |
60 | If | |
61 | .Nm vipw | |
62 | rejects the new password file, the user is prompted to re-enter | |
63 | the edit session. | |
64 | .Pp | |
65 | Once the information has been verified, | |
66 | .Nm vipw | |
67 | uses | |
68 | .Xr pwd_mkdb 8 | |
69 | to update the user database. This is run in the background, and, | |
70 | at very large sites could take several minutes. Until this update | |
71 | is completed, the password file is unavailable for other updates | |
72 | and the new information is not available to programs. | |
73 | .Sh ENVIRONMENT | |
74 | If the following environment variable exists it will be utilized by | |
75 | .Nm vipw : | |
76 | .Bl -tag -width EDITOR | |
77 | .It Ev EDITOR | |
78 | The editor specified by the string | |
79 | .Ev EDITOR | |
80 | will be invoked instead of the default editor | |
