Old tar (v7) and Posix (well, SUSv2) have no dash before the key (the first argument to tar). They take option values from the next arguments in the order the options appear in the key string: tar xfbv file.tar 20000 x - no arg f - take next arg (file.tar) b - take next arg (20000) v - no arg. Using a dash is a gnu-ism and should be avoided in scripts. harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private [EMAIL PROTECTED], [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
