prtsweep \- sweep old files from the ports directories
.B prtsweep
[\-a] [\-d] [\-n] [PORTDIR ...]
The \fIprtsweep\fP perl script sweeps port directories, deleting unneeded files.
"Unneeded" here means not listed in the .signatures file, and not the
built package
All other files are removed. If a traversal of the ports collections in automatic mode
reveals an empty directory (or one of the arguments in [PORTDIR ...] is similarly missing
the required \fBPkgfile\fP), the directory can be removed with the \fI\-d\fP option.
The following options are supported:
.I "\-a"
This is the automatic mode. In this mode \fIprtsweep\fP reads the port
collections defined by /etc/ports/*.{git,httpup,rsync} files and cleans all ports
in those collections.
.I "\-d"
Removes empty directories completely. This happens when ports are moved for
example from opt to contrib or vice versa. Note that this option only
deletes empty directories, so accidently removing whole directory trees
should not happen, even if you use
prtsweep \-d /
To remove these moved ports completely you can run \fIprtsweep\fP twice:
the first pass removes everything under the directory of the dropped port,
the second pass removes the empty directory.
.I "\-p"
Also removes the built package.
.I "\-n"
Dry-run. Do not remove anything really.
.I "\-q"
Quiet mode. Print messages only for the files that are deleted, not for the
file that are kept. Equivalent to \fBprtsweep [args] | grep -v "keeping"\fP.
In automatic mode, \fBprtsweep\fP gets a list of active port collections
from /etc/ports/*.{rsync,httpup}, and for each collection descends into the
individual port directories to read the associated .signature files.
After reading .signature, \fBprtsweep\fP will be able to distinguish between
needed sources and unneeded clutter. \fBprtsweep\fP then compares the contents
of the port directory with this list of needed files, and any non-matching
files are deleted (or just printed to stderr if dry-run mode is enabled).
\fBprtsweep\fP does not distinguish between the current version of the built package
and previous versions. All built packages beginning with the name of the port directory (and
ending in pkg.tar.*) are normally shielded from deletion, except when you pass the option
\fB\-p\fP. Passing this option allows \fBprtsweep\fP to delete every built package,
no matter how old. If you want to keep the current version of the built package but delete
older versions, you can use the companion script \fBprtwash(1)\fP instead.
After a real cleaning by \fBprtsweep\fP (not dry-run mode), each port
directory should contain only the Pkgfile, source files listed in .signature,
and the built package (if present, and option -p was not given on the command
You can call \fIprtsweep\fP with one port:
root@hostname:/root # prtsweep /usr/ports/opt/dialog
=======> /usr/ports/opt/dialog
+ removing file dialog-0.9b-20020814.tgz
Or you could call the automatic mode, which scans your supfiles in /etc/ports
for all ports directories and cleans them automatically:
root@hostname:/root # prtsweep -a
=======> /usr/ports/clc/stable/atop
+ removing file atop-1.8.tar.gz
=======> /usr/ports/clc/stable/coldsync
+ removing file coldsync-2.2.5-gcc3.diff
+ removing file coldsync-2.2.5.tar.gz
=======> /usr/ports/clc/stable/dnsmasq
+ removing file dnsmasq-1.10.tar.gz
