Hello, GNU tar maintainers,
the manual
<http://www.gnu.org/software/tar/manual/html_node/tar_126.html#SEC126>
says
First of all, compressed archives cannot be modified, i.e., you cannot
update ('--update' ('-u')) them or delete ('--delete') members from
them. Likewise, you cannot append another tar archive to a compressed
archive using '--append' ('-r')).
As far as I understand
<http://www.gnu.org/software/tar/manual/html_node/tar_41.html#SEC41>
(operations '--append' and '--concatenate'), this should say
First of all, compressed archives cannot be modified, i.e., you cannot
update ('--update' ('-u')) them or delete ('--delete') members from or
add ('--append' ('-r')) members to them. Likewise, you cannot append
another tar archive to a compressed archive using ('--concatenate'
('--catenate', '-A')).
I think, the cause of this error in the manual page is the suboptimal
name of the operation '--append', which should rather have been called
'--add'. So, maybe, the operation name '--add' as an alias (with a
suggestion to no longer use the name '--append') should be added?
If I recall correctly, this also disturbed users on this mailing list.
Thanks in advance,
Helmut
