NAME
mkpkg, inspkg, seal, unseal - automatic software distribution
SYNOPSIS
mkpkg [ options ] files
inspkg [ options ] files
seal [ -k ] [ -K keyfile ] [ file ... ]
unseal [ -k ] [ -K keyfile ] [ file ... ]
DESCRIPTION
These commands are the basis of automatic software distribution as used
in ship(1).
Mkpkg collects files and directories into a `package', which is written
on the standard output. It reads the standard input for remarks to in‐
clude in the package, and will prompt for these if the standard output
is a terminal.
Inspkg opens packages and installs their contents, printing the remarks
included in the package. Since inspkg has no special privileges, in‐
stallation should be done by the owner of the files being installed or
by the super-user.
The information contained in a package includes the full pathnames of
the objects, links among the objects, their owners, groups, file modes,
and modification dates. Owners and groups are stored as their charac‐
ter representations, to avoid problems if systems use different numeric
codes for a single owner or group. Nonexistent objects are noted for
deletion by inspkg.
Options are:
-v Verbose mode.
-n If packaging, don't ask for remarks. If installing, skip the
actual installation, but do backup if requested.
-b Backup mode, meaningful only with inspkg. Write on the standard
output a package that contains everything that was destroyed
during installation.
-Dpath1=path2
Pretend that a pathname beginning with path1 really begins with
path2.
A package is an archive (see ar(1)) with a component named `instruc‐
tions' that contains installation information.
Seal produces on the standard output a file containing the same infor‐
mation as the concatenation of all its input files, in a form suitable
for shipment by mail. If no input files are specified, seal reads its
standard input.
Unseal reads files produced by seal and produces the original file con‐
tents as its output.
A sealed file includes a checksum; if the -k option is specified, seal
prompts for a key to encrypt the data before calculating the checksum.
If the -K option is specified, the program uses the first line of the
given keyfile to supply the key. Subsequent lines are ignored.
