Zum Anfertigen von Backups ist es unerlässlich und für einen Linuxuser ein Standardwerkzeug. Das “.tar”-Archiv:

Die oder besser gesagt eine Syntax für ein tar (anfertigen:)

tar -cvzf file.tar.gz inputfile1 inputfile2

Die entsprechende Syntax um das tar (zu entpacken:)

tar -xvzf file.tar.gz

Die Optionen für tar / gzip im Detail:

literal, locale, shell, shell-always, c, escape

-r, –reverse reverse order while sorting

-R, –recursive list subdirectories recursively

-s, –size (with -l, print size of each file, in blocks)

-S  (sort by file size)

–sort=WORD   (extension -X, none -U, size -S, time -t,)

version -v, status -c, time -t, atime -u,

access -u, use -u

–time=WORD            with -l, show time as WORD instead of modification

time: atime, access, use, ctime or status; use

specified time as sort key if –sort=time

–time-style=STYLE     with -l, show times using style STYLE:

full-iso, long-iso, iso, locale, +FORMAT.

FORMAT is interpreted like `date’; if FORMAT is

FORMAT1<newline>FORMAT2, FORMAT1 applies to

non-recent files and FORMAT2 to recent files;

if STYLE is prefixed with `posix-’, STYLE

takes effect only outside the POSIX locale

-t                         sort by modification time

-T, –tabsize=COLS         assume tab stops at each COLS instead of 8

-u                         with -lt: sort by, and show, access time

with -l: show access time and sort by name

otherwise: sort by access time

-U                         do not sort; list entries in directory order

-v                         sort by version

-w, –width=COLS           assume screen width instead of current value

-x                         list entries by lines instead of by columns

-X                         sort alphabetically by entry extension

-1                         list one file per line
