DESCRIPTION
+ +
+ + +
+ + Gzip encodes files with a hybrid Lempel-Ziv 1977 and Huffman compression + algorithm known as deflate. Most of the time, the resulting file + is smaller, and will never be much bigger. Output files are named + by taking the last path element of each file argument and appending + .gz; if the resulting name ends with + .tar.gz, it is converted to .tgz instead. Gunzip reverses the + process. Its output files are named by taking the last path element + of each file argument, converting .tgz to .tar.gz, and stripping + any .gz; the resulting name must be different from the original + name. +
+ + Bzip2 and bunzip2 are similar in interface to gzip and gunzip, + but use a modified Burrows-Wheeler block sorting compression algorithm. + The default suffix for output files is .bz2, with .tar.bz2 becoming + .tbz. Bunzip2 recognizes the extension .tbz2 as a synonym for + .tbz. +
+ + Zip encodes the named files and places the results into the archive + zipfile, or the standard output if no file is given. Unzip extracts + files from an archive created by zip. If no files are named as + arguments, all of files in the archive are extracted. A directory’s + name implies all recursively contained files and subdirectories. + +
+ + None of these programs removes the original files. If the process + fails, the faulty output files are removed. +
+ + The options are:
+ −c          Write to standard output rather than creating an output file.
+ −i          Convert all archive file names to lower case.
+ −s          Streaming mode. Looks at the file data adjacent to each compressed + file rather than seeking in the central file directory. This is + the mode used by unzip if no zipfile is specified. If −s is given, + −T is ignored.
+ −t          List matching files in the archive rather than extracting them.
+ −T          Set the output time to that specified in the archive.
+ −1 .. −9      Sets the compression level. −1 is tuned for speed, −9 + for minimal output size. The best compromise is −6, the default.
+ −v          Produce more descriptive output. With −t, adds the uncompressed + size in bytes and the modification time to the output. Without + −t, prints the names of files on standard error as they are compressed + or decompressed.
+ −D          Produce debugging output.

BUGS
+ +
+ + Unzip can only extract files which are uncompressed or compressed + with the deflate compression scheme. Recent zip files fall into + this category.
