我正在尝试将几个目录写入磁带。每个目录有一个 tar 命令。
所以我有以下示例文件/目录结构：
user@host1:~/temp/original % find .
.
./foo1
./foo1/foo1.a
./foo1/foo1.b
./foo1/foo1.c
./foo1/foo1.1
./foo2
./foo2/foo2.a
./foo2/foo2.b
./foo2/foo2.c
./foo2/foo2.2
./foo3
./foo3/foo3.a
./foo3/foo3.b
./foo3/foo3.c
./foo3/foo3.3
我倒带并擦除磁带，我希望这就像使用空白磁带一样。
user@host1:~/temp/original % mt -f /dev/sa0 rewind
user@host1:~/temp/original % mt -f /dev/sa0 erase
user@host1:~/temp/original % mt -f /dev/sa0 rewind
user@host1:~/temp/original % mt -f /dev/sa0 status
