TAR

Tarball...


Although Tarballing sounds like a whole lot more fun than it actually is... it's a utility that stores one or more files in a single archieve. The format of the tar command is:

tar [options] [FileToCreate] [FileListToInclude]

Not included in the man page for tar... at least not on Debian.

Common options:

Option Description
-c Create a new file
-v Verbose... tell me what you are doing.
-z Feed the output into gzip
-f Create a file.

There are lots of other options...

Example:

tar -cvzf [tarball.file] File1.txt File2.txt File3.txt File4.txt

OR

tar -cvzf [tarball.file] File*.txt

Functions...


The first command line parameter is the function to perform. One of Acdrtux There should be only one of them... they don't play nice together.

Option Word Descrption
-A --catenate --concatenate Append the file to an existing archieve.
-c --create Create a new file.
-d --diff --compare Difference between two files.
--delete Delete from archieve.
-r --append Append files to the end archieve.
-t --list List the contents of an archieve.
--test-label Test the vol label and exit.
-u --update Append newer files.
-x --extract --get Extract the files from the archieve.

Options...


Options are different than functions. Where some functions can not be seen together, like c and x, options are not that way. May not make sense... but your mother won't be calling if you do.

There are a miriad of options when Tarballing, here are just a few of them... the important ones... I think.

Option Long Word Description
--add-file add given file to the archieve. --add-file=myfile.txt
-C --directory <dir> change to directory dir
--checkpoint Display a progress message every nth record. Default 10.
--checkpoint-action=<action> execute action on every checkpoint.
--exclude=<pattern> Exclude files that match pattern
-f --file <filename> The file to work on*
--group=<name> Force the name of group on added files.
-h --dereference Follow symlinks and dump the files they point to.
--ignore-case Ignore case

-N --newer, --after-date <date or file> only stores files newer than date or file
--overwrite Overwrite existing files when extracting.
--owner=<name> force name as owner
--recursion Recurse into subdirectories (default)
--no-recursion Do NOT recurse into subdirectories
--remove-files Remove files after adding to the archieve
-T --files-from <file> Get file names to archieve from file
-v --verbose Verbosely list files processed.
-W --verify attempt to verify the archieve after writing it
-X --excllude-from<file> Exclude patterns listed in file
-z --gzip --gunzip Use gzip to compress files

NOTE: the -f options needs to be the last in line because the next command line argument is the file name to work on.

Listing the Contents of a Tarball...


To list the contents of an archieve...

tar -ztvf [tarFileName]

The z is for a zip file, leave that out if it is not a zip file. The t lists the contents. The v is for verbose and f is the switch for the file which must be the last switch so the file name follows it.

Un-Tarballing...


Once you make an archieve... eventually... you have to unpack it. Use the same command to unpack it as you did to pack it... but... with the parameter. For eXtract.

-x

tar -xvf [tarball/filename]

You can't use x and c together. It isn't fun and tar doesn't like it.
