Operations

--append

-r

Appends files to the end of the archive. See section How to Add Files to Existing Archives: --append.

--catenate

-A

Same as `--concatenate'. See section Combining Archives with --concatenate.

--compare

-d

Compares archive members with their counterparts in the file system, and reports differences in file size, mode, owner, modification date and contents. See section Comparing Archive Members with the File System.

--concatenate

-A

Appends other tar archives to the end of the archive. See section Combining Archives with --concatenate.

--create

-c

Creates a new tar archive. See section How to Create Archives.

--delete

Deletes members from the archive. Don't try this on a archive on a tape! See section Removing Archive Members Using `--delete'.

--diff

-d

Same `--compare'. See section Comparing Archive Members with the File System.

--extract

-x

Extracts members from the archive into the file system. See section How to Extract Members from an Archive.

--get

-x

Same as `--extract'. See section How to Extract Members from an Archive.

--list

-t

Lists the members in an archive. See section How to List Archives.

--update

-u

@FIXME{It was: A combination of the `--compare' and `--append' operations. This is not true and rather misleading, as --compare (--diff, -d) does a lot more than --update (-u) for ensuring files are identical.} Adds files to the end of the archive, but only if they are newer than their counterparts already in the archive, or if they do not already exist in the archive. See section Updating an Archive.
