The $param can't be used for all command's options, for example "help pwrite" include: -Z N -- zeed the random number generator (used when writing randomly) (heh, zorry, the -s/-S arguments were already in use in pwrite) We should make param="-Z N", not only "-Z". After this patch, we can run this function as: _require_xfs_io_command pwrite -Z N Signed-off-by: Zorro Lang <zlang@xxxxxxxxxx> --- Hi, I did 2 changes in "[PATCH 1/2] common/rc: modify _require_xfs_io_command function": 1. change "$command help" to "help $command" 2. change "param=$2" to "shift; param=\"$*\"" V2 patch give up the 1st change (Dave explained why we don't change that), remain the 2nd change as below.
