Packen und Entpacken (Linux)
gzip functions as a compression algorithm only.
Because of various reasons some of which hearken back to the era of tape drives, Unix uses a program named
tar to archive data, which can then be compressed with a compression program like
In order to "zip" a directory, the correct command would be
tar -zcvf archive.tar.gz directory/
This will tell
tar to c (create) an archive from the files in
tar is recursive by default), compress it using the z (gzip) algorithm, store the output as a f (file) named
archive.tar.gz, and v(verbosely) list (on /dev/stderr so it doesn't affect piped commands) all the files it adds to the archive.
tar command offers
gzip support (via the
-z flag) purely for your convenience. The
gzipcommand/lib is completely separate. The command above is effectively the same as
tar -cv directory | gzip > archive.tar.gz
To decompress and unpack the archive into the current directory you would use
tar -zxvf archive.tar.gz
That command is effectively the same as
gunzip < archive.tar.gz | tar -xv
tar has many, many, MANY other options and uses as well; I heartily recommend reading through its manpage sometime.
tar -zcvf archive-name.tar.gz directory-name
tar xfv foo.tar.gz tar -xjf foo.tar.bz2 tar -xvJf foo.tar.xy tar -xvJf foo.tar.xz
