MKPKG(8) System Manager's Manual MKPKG(8) NAME mkpkg, inspkg, seal, unseal - package files for automatic software dis- tribution SYNOPSIS mkpkg [ option ... ] file ... inspkg [ option ... ] [ file ... ] seal [ option ] [ file ... ] unseal [ option ] [ file ... ] DESCRIPTION These programs are used by ship(8) to keep files identical across ma- chines. Mkpkg packages files and writes the result on the standard output. In- spkg installs the named packages or the standard input. Non-existent files given to mkpkg are deleted upon installation. Di- rectories are copied with all their contents. Hard links are repro- duced. Symbolic links and special files are reproduced with the same inode contents. File modification and access times and owner and group names are reproduced as far as possible. Old versions of files are re- moved before installation: inspkg needs write permission in containing directories. Options for both mkpkg and inspkg: -v Place running commentary on the standard error file. -Dpath1=path2 Pretend that any pathname beginning with path1 really begins with path2. Relative pathnames are extended to full path- names before comparison. Options for mkpkg; only one may occur: -xcommand Include in the package instructions to execute the shell command after all files have been installed. Command is un- affected by option -D. -Xfile Include in the package instructions to run the shell script file after all files have been installed. The file name is subject to option -D. Options for inspkg: -n Skip the actual installation, but verify the input packages and produce a backup if requested. -b Write on the standard output a backup package that contains whatever was destroyed. A package is an ar(1) archive containing an extra ASCII file named Seal concatenates the named files or the standard input onto the stan- dard output in an error-detecting form suitable for shipment by mail(1). Unseal reverses the process, concatenating copies of all the original inputs onto the standard output. When asd(8) uses uucp(1), it sends sealed packages. A sealed file is printable, has fewer than 128 characters per line, and has no lines consisting of a single period. The first line is and the last one begins with Other lines, such as mail headers, can be added to either end of a sealed file without hindering unseal. Options for seal and unseal: -k A key will be demanded to encrypt the checksum calculation. -K keyfile Same, but taking the first line of keyfile as the key.
