Message: Missing file name after "f"
Cause: You specified the f option but you did not specify the name of an archive file as
its argument.
Action: Provide the missing file name.
Message: Must specify one of ’c’, ’r’, ’t’, ’u’, or ’x’
Cause: tar requires that you specify one of the c, r, t, u,orx options as the first
character of its option string. You failed to do this. Specify one of the required
options at the beginning of the option string.
Message: opening archive "filename": system error
Cause: See syserror(3).
Action: See syserror(3).
Message: tape archive medium not seekable
Cause: You attempted to use the replace (r) option on an archive file that was not seek-
able.
Action: Only use the r option with archive files that are seekable.
Message: TAR file already set
Cause: You specified the f option more than once on the command line.
Action: Specify the f option only once.
Message: ’u’ function not implemented--using ’r’
Cause: You attempted to use the u option which is not currently implemented. tar
uses the r option instead.
Action: Use the pax command instead of tar.
Message: Unknown option "–option"
Cause: You specified an option that is not valid for tar.
Action: Check the DESCRIPTION section for a list of valid tar options.
Message: Unknown tape density "density"
Cause: You specified a tape drive number followed by an argument that should be a
tape density, but the argument was not l, m,orh.
Action: Specify a valid tape density (l, m,orh).
Message: Warning: blocking factor number not portable to UNIX
Cause: You specified a blocking factor (blocksize) that was larger than 20. This may
create an archive that does not work on a
UNIX system.
Action: To guarantee portability to a UNIX system, use a blocksize of 20 or less. A larger
value may work but is not guaranteed.
