DESCRIPTION

This manual page documents the GNU version of tar , an archiving program designed to store and extract files from an archive file known as a tarfile. A tarfile may be made on a tape drive, however, it is also common to write a tarfile to a normal file. The first argument to tar must be one of the options: Acdrtux, followed by any optional functions. The final arguments to tar are the names of the files or directories which should be archived. The use of a directory name always implies that the subdirectories below should be included in the archive.  

FUNCTION LETTERS

One of the following options must be used:
-A, --catenate, --concatenate
append tar files to an archive
-c, --create    
create a new archive
-d, --diff, --compare
find differences between archive and file system
--delete                
delete from the archive (not for use on mag tapes!)
-r, --append            
append files to the end of an archive
-t, --list              
list the contents of an archive
-u, --update            
only append files that are newer than copy in archive
-x, --extract, --get            
extract files from an archive
 

OTHER OPTIONS

--atime-preserve       
don't change access times on dumped files
-b, --block-size N      
block size of Nx512 bytes (default N=20)
-B, --read-full-blocks  
reblock as we read (for reading 4.2BSD pipes)
-C, --directory DIR     
change to directory DIR
--checkpoint            
print directory names while reading the archive
-f, --file [HOSTNAME:]F 
use archive file or device F (default /dev/rmt0)
--force-local           
archive file is local even if has a colon
-F, --info-script F --new-volume-script F
run script at end of each tape (implies -M)
-G, --incremental       
create/list/extract old GNU-format incremental backup
-g, --listed-incremental F
create/list/extract new GNU-format incremental backup
-h, --dereference       
don't dump symlinks; dump the files they point to
-i, --ignore-zeros      
ignore blocks of zeros in archive (normally mean EOF)
-j, -I, --bzip
filter the archive through bzip2. Note: -I is deprecated and may get a different meaning in the near future.
--ignore-failed-read    
don't exit with non-zero status on unreadable files
-k, --keep-old-files    
keep existing files; don't overwrite them from archive
-K, --starting-file F   
begin at file F in the archive
-l, --one-file-system

-m, --modification-time 
don't extract file modified time
-M, --multi-volume      
create/list/extract multi-volume archive
-N, --after-date DATE, --newer DATE

--same-owner            
create extracted files with the same ownership
-S, --sparse            
handle sparse files efficiently
-T, --files-from=F      
get names to extract or create from file F
--null
