I have a repository called "sandbox" whose HEAD is at revision 20. I would like to dump revisions 1 to15 and then from 18 to19. Basically I want to skip revision 16,17 and 20. The command:
# svnadmin dump -r 1:15 -r 18:19 sandbox > sanbox-dumpfile gives error message: svnadmin: Multiple revision arguments encountered; try '-r N:M' instead of '-r N -r M' and the command: #svnadmin dump -r 1:15,18:19 sandbox > sanbox-dumpfile gives error message: svnadmin: Syntax error in revision argument '1:15,18:19' How can I do this? Thanks.
