It does not appear that -r works in conjunction with -j: $ echo example > example.txt $ tar -cjf example.tar.bz2 example.txt $ tar -tjf example.tar.bz2 example.txt $ echo example2 > example2.txt $ tar -rjf example.tar.bz2 example2.txt zsh: abort tar -rjf example.tar.bz2 example2.txt
But no error message is given to say that -r and -j are incompatible, and there is no mention of any such incompatibility in the man or info pages. Are they really incompatible? Or is the functionality of using them together just broken? Note that -A and -j don't appear to work together either. $ tar --version tar (GNU tar) 1.14 +CVE-2006-0300 +CVE-2006-6097 Copyright (C) 2004 Free Software Foundation, Inc. Platform: OS X 10.4.11.
