Ports 搜索

This is the set of GNU shar utilities. This port installs them with the letter "g" prepended to their names, to avoid conflict with the FreeBSD base system. The uudecode and uuencode commands are omitted (BSD versions are present in the base system). The shar utilities deal with shar files, so-called shell archives, which are scripts suitable for transmission by e-mail or Usenet. When a shar file is executed, the files it contains are unpacked without the need for any software other than the shell itself and sed. Because they are scripts, shell archives from strangers should be read before executing them, to check for harmful commands. synopses from the info pages: * gmail-files: Send files to remote site. * gmailshar: Make and send a shell archive. * gremsync: Synchronize remote directory trees using e-mail. * gshar: Make a shell archive. * gunshar: Explode a shell archive.

Unalz is a ZLIB-licensed unarchiver for AlZip format which requires proprietary and Win32-only software but widely used in Korea.

Unzip will list, test, or extract files from a ZIP archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified ZIP archive. Unzip is compatible with archives created by PKWARE's PKZIP, but in many cases the program options or default behaviors differ. Zipinfo lists technical information about files in a ZIP archive, most commonly found on MS-DOS systems. Such information includes file access permissions, encryption status, type of compression, version and operating system or file system of compressing program, and the like. Funzip acts as a filter; that is, it assumes that a ZIP archive is being piped into standard input, and it extracts the first member from the archive to stdout. If there is an argument, then the input comes from the specified file instead of from stdin. Unzipsfx may be used to create self-extracting ZIP archives from previously created ZIP archives.

xDMS is an archiver unpacker for the Amiga DMS file format. It supports decompression of files compressed using all known DMS compression modes, including old and obsolete ones, and also encrypted files, for 100% compatibility.

This the Unix port of the Amiga XPK library. The XPK system consists of a master library (libxpkmaster.so) and several (un)packer sublibraries (libxpkXXXX.so). Application programs only use the master library directly: the master library takes care of loading and using the sublibraries. Each sublibrary implements one type of compression. There are different libraries for different types of data. When unpacking the applications do not need to know which library was used to pack the data -- the appropriate library needs to be installed.

Zip is a compression and file packaging utility. It is compatible with PKZIP 2.04g (Phil Katz ZIP) for MSDOS systems. There is a companion to zip called unzip (of course) which you can also install from the ports/package system.

Sometimes, when you run 2 different .ZIP programs on the same data (PKZIP & KZIP for example), some files get compressed better in one program, while other files get compressed better in the other. ZIPMIX will take the best files from each one and create a new output file, which is guaranteed to be equal to or smaller in size to both of the input files. ZIPMIX can also be used to perform boolean operations on ZIP files, such as merging 2 ZIP files together, or updating a new file (with some tricks).

Zopfli is a new zlib (gzip, deflate) compatible compressor. This compressor takes more time (~100x slower), but compresses around 5% better than zlib and better than any other zlib-compatible compressor we have found.

Zutils is a collection of utilities able to deal with any combination of compressed and non-compressed files transparently. If any given file, including standard input, is compressed, its decompressed content is used. Compressed files are decompressed on the fly; no temporary files are created. The provided utilities are: Zcat - Decompresses and copies files to standard output. Zcmp - Decompresses and compares two files byte by byte. Zdiff - Decompresses and compares two files line by line. Zgrep - Decompresses and searches files for a regular expression. Ztest - Tests integrity of compressed files. Zupdate - Recompresses files to lzip format. The supported compressors are bzip2, gzip, lzip, and xz.
