-r

Replaces, or adds, files in the library. If the library does not exist, a new library file is created and a diagnostic message is written to standard error. -q is an alias for -r.

If file_list is not specified and the library exists, the results are undefined. Files that replace existing files do not change the order of the library.

If the -u option is used, then only those files with dates of modification later than the library files are replaced.

If the -a, -b, or -i option is used, then pos_name must be present and specifies that new files are to be placed after (-a) or before (-b or -i) pos_name. Otherwise the new files are placed at the end.
