These four programs all operate on the normal and shadow password and group files:

/etc/gshadow\&.

Each program acquires the necessary locks before conversion\&.
|

\fBpwconv\fR
|

and
|
||
\fBgrpconv\fR
|
||
are similar\&. First, entries in the shadowed file which don\*(Aqt exist in the main file are removed\&. Then, shadowed entries which don\*(Aqt have `x\*(Aq as the password in the main file are updated\&. Any missing shadowed entries are added\&. Finally, passwords in the main file are replaced with `x\*(Aq\&. These programs can be used for initial conversion as well to update the shadowed file if the main file is edited by hand\&.
