.SH Name
vipw \- edit the password file
.SH Syntax
.B vipw
.SH Description
.NXR "vipw command"
.NXAM "passwd file (general)" "vipw command"
.NXR "password file" "editing"
The
.PN vipw
command
edits the password file while setting the appropriate locks
and doing any necessary processing after the password file is unlocked.
If the password file is already being edited, then you will be told
to try again later.  The 
.PN vi
editor will be used unless the environment variable EDITOR indicates
an alternate editor.  
The
.PN vipw
command
performs a number of consistency checks on the password entry for
root, and does not allow a password file with a corrupted root entry
to be installed.
.P
If the hashed 
.PN passwd 
database exists
.PN vipw
will automatically invoke
.MS mkpasswd 8
on it to keep it synchronized with the 
.PN passwd 
file.
.SH Files
.PN /etc/ptmp
