"find [--set-root[=DIR]] [--devices=DEVLIST] [--ignore-floppies] [--ignore-cd] [FILENAME] [CONDITION]",
"Search for the filename FILENAME in all of partitions and print the list of"
" the devices which contain the file and suffice CONDITION. CONDITION is a"
" normal grub command, which return non-zero for TRUE and zero for FALSE."
" DEVLIST specify the search devices and order,the default DEVLIST is upnhcf."
" DEVLIST must be a combination of these letters (u, p, n, h, c, f)."
" If the option --set-root is used and FILENAME is found on a device, then"
" stop the find immediately and set the device as new root."
" If the option --ignore-floppies is present, the search will bypass all"
" floppies. And --ignore-cd will skip (cd)."
已知当前U盘的情况下确实可以通过CONDITION来排除u盘。
但是,假如说用户同时插入了多个U盘呢? |
