.Sh DESCRIPTION
|
|
|
|
|
.Nm
|
|
|
|
|
uses information provided by
|
|
|
|
|
.Xr dpb 1
|
|
|
|
|
to remove obsolete distfiles:
|
|
|
|
|
each time
|
|
|
|
|
.Xr dpb 1
|
|
|
|
|
is run for a full scan of the ports tree, it appends to
|
|
|
|
|
an history log that records obsolete distfiles.
|
|
|
|
|
.Pp
|
|
|
|
|
.Nm
|
|
|
|
|
can be used to prune that log prior to a given
|
|
|
|
|
.Ar timestamp
|
|
|
|
|
and remove the corresponding distfiles.
|
|
|
|
|
.Pp
|
|
|
|
|
For normal files,
|
|
|
|
|
.Nm
|
|
|
|
|
verifies
|
|
|
|
|
.Xr sha256 1
|
|
|
|
|
checksums prior to removal.
|
|
|
|
|
.Nm
|
|
|
|
|
also removes links under
|
|
|
|
|
.Pa by_cipher/sha256 ,
|
|
|
|
|
but it trusts that the checksums for these are accurate.
|
|
|
|
|

|

|
The
|
|
|
|
|
