linux tar use example

some example:

//create verbose file
tar cvf filesname.tar      

tar cvfz filesname.tar.gz  

// create verbose tar file (only tar ,not compress with ‘z’)
tar cvf filesname.tar source_dir

// create verbose gzip file (tar and compress with ‘z’)
tar cvzf filesname.tar.gz source_dir

// list verbose file
tar tvf filesname.tar

//extract verbose file
tar xvf filesname.tar

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

stay in local file system when creating an archive

-L, –tape-length N

change tapes after writing N*1024 bytes

-m, –modification-time

don’t extract file modified time

-M, –multi-volume

create/list/extract multi-volume archive

-N, –after-date DATE, –newer DATE

only store files newer than DATE

-o, –old-archive, –portability

write a V7 format archive, rather than ANSI format

-O, –to-stdout

extract files to standard output

-p, –same-permissions, –preserve-permissions

extract all protection information

-P, –absolute-paths

don’t strip leading `/’s from file names

–preserve

like -p -s

-R, –record-number

show record number within archive with each message

–remove-files

remove files after adding them to the archive

-s, –same-order, –preserve-order

list of names to extract is sorted to match archive

–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

-T reads null-terminated names, disable -C

–totals

print total bytes written with –create

-v, –verbose

verbosely list files processed

-V, –label NAME

create archive with volume name NAME

–version

print tar program version number

-w, –interactive, –confirmation

ask for confirmation for every action

-W, –verify

attempt to verify the archive after writing it

–exclude FILE

exclude file FILE

-X, –exclude-from FILE

exclude files listed in FILE

-Z, –compress, –uncompress

filter the archive through compress

-z, –gzip, –ungzip

filter the archive through gzip

–use-compress-program PROG
