- Uses of gzip:
-
- 1. To compress a file:
-
- gzip file
-
- Produces file.gz
-
- 2. To uncompress a file which has been compressed with gzip:
-
- gunzip file
- or
- gunzip file.gz
-
- 3. To uncompress a file which has been compressed with UN*X
- compress:
-
- gunzip file.Z
- or
- cat file.old | gunzip > file.new
-
- 4. To convert a file from UN*X compression to gzip compression:
-
- cat file.Z | gunzip | gzip > file.new
-
- Further information on gzip and gunzip may be obtained by reading
- the appropriate man pages, which are provided as part of the source
- code.
-
- Here is one of the gzip README files (from wuarchive.wustl.edu):
- ------------------------------------------------------------------------------
- Because the `compress' utility is covered by patents (US 4,464,650 and
- 4,558,302), we cannot use it; it is not free software.
-
- Instead, the GNU Project uses the `gzip' program, which is free of known
- software patents and also compresses better than `compress'. Files
- compressed with this method end with `.gz'.
-
- Gzip can also uncompress files compressed with `compress' (i.e. files
- ending in `.Z'), since the uncompression algorithm is not patented.
-
- To extract sources that are in files ending in `.tar.gz' you can use the
- command
-
- gzip -d < foo.tar.gz | tar xf -
-
- where `foo.tar.gz' is the name of the file.
-
- Gzip is available in source form on this ftp archive[wuarchive.wustl.edu],
- in the file gzip-N.N.shar, gzip-N.N.tar, and gzip-N.N.tar.gz (the last for
- people who already have gzip but want to get a newer version, since the
- gzipped file will transfer faster). Gzip is also available as a DOS
- executable in the file gzip-N.N.msdos.exe. To find a VMS executable,
- read gzip-vms.README.
