VIPW(8) OpenBSD System Manager's Manual VIPW(8)NAMEvipw - edit the password file
SYNOPSISvipwDESCRIPTIONvipw edits the password file after setting the appropriate locks, and
does any necessary processing after the password file is unlocked. If
the password file is already locked for editing by another user, vipw
will ask you to try again later. The default editor for vipw is vi(1).
vipw performs a number of consistency checks on the password entries, and
will not allow a password file with a ``mangled'' entry to be installed.
If vipw rejects the new password file, the user is prompted to re-enter
the edit session.
Once the information has been verified, vipw uses pwd_mkdb(8) to update
the user database. This is run in the background, and, at very large
sites could take several minutes. Until this update is completed, the
password file is unavailable for other updates and the new information is
not available to programs.
Which type of cipher is used to encrypt the password information depends
on the configuration in login.conf(5).
ENVIRONMENT
If the following environment variable exists it will be utilized by vipw:
EDITOR The editor specified by the string EDITOR will be invoked instead
of the default editor vi(1).
