Description

-A, --catenate, --concatenate Append archive to the end of another archive. The arguments are treated as the names of archives to append. All archives must be of the same format as the archive they are appended to, otherwise the resulting archive might be unusable with non-GNU implementations of tar. Notice also that when more than one archive is given, the members from archives other than the first one will be accessible in the resulting archive only if using the -i (--ignore-zeros) option. Compressed archives cannot be concatenated.
