ASD(8) ASD(8) 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 distribu- tion 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 include 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, installation 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 character 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. ASD(8) ASD(8) A package is an archive (see ar(1)) with a component named `instructions' that contains installation information. Seal produces on the standard output a file containing the same information 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 origi- nal file contents as its output. A sealed file includes a checksum; if the -k option is spec- ified, 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.
