There are several options for archiving and compressing groups of files or directories. The mostly commonly used options are:
See the official documentation for tar for more information.
Saves many files together into a single archive file, and restores individual files from the archive. Includes automatic archive compression/decompression options and special features for incremental and full backups.
(list contents of archive somefile.tar) $ tar tvf somefile.tar (extract contents of somefile.tar) $ tar xvf somefile.tar (extract contents of gzipped archive somefile.tar.gz) $ tar xzvf somefile.tar.gz (extract contents of bzip2 archive somefile.tar.bz2) $ tar xjvf somefile.tar.bz2 (archive all ".c" files in current directory into one archive file) $ tar cvf somefile.tar *.c (archive and gzip-compress all files in a directory into one archive file) $ tar czvf somefile.tar.gz somedirectory/ (archive and bzip2-compress all files in a directory into one archive file) $ tar cjvf somefile.tar.bz2 somedirectory/
Other arguments for tar can be explored by using the man tar command.
The standard compression system for all GNU software.
(compress file somefile - also removes uncompressed file) $ gzip somefile (uncompress file somefile.gz - also removes compressed file) $ gunzip somefile.gz
See the official documentation for bzip for more information.
Strong, lossless data compressor based on the Burrows-Wheeler transform. Stronger compression than gzip.
(compress file somefile - also removes uncompressed file) $ bzip2 somefile (uncompress file somefile.bz2 - also removes compressed file) $ bunzip2 somefile.bz2
There are several other, less commonly used, options available as well:
