NAME
vipw
- edit the password file
SYNOPSIS
[-d directory
]
DESCRIPTION
The
utility 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,
will ask you
to try again later.
The default editor for
is
vi(1).
When run without options,
will work with the password files in
/etc
The
-d
option may be used to specify an alternative
directory
to work with.
The
utility 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
rejects the new password file, the user is prompted to re-enter
the edit session.
Once the information has been verified,
uses
pwd_mkdb8
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.
ENVIRONMENT
If the following environment variable exists it will be utilized by
:
EDITOR
The editor specified by the string
EDITOR
will be invoked instead of the default editor
vi(1).
This can be used to allow a script to non-interactively modify the
password file.
The mechanism for checking for password file modifications requires that
EDITOR
run for at least one second.
Non-interactive editor scripts should invoke
sleep(1)
or equivalent to ensure this happens.
