fdisk -l不复杂，但是看不到文件系统类型，只能看到分区类型，以Redhat 9为例：
[root@redhat9 root]# fdisk -l
Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 1012 8024467+ 83 Linux
/dev/sda3 1013 1044 257040 82 Linux swap
df -Tk是可以的，不过df -Th更友好一些，容量大小是以易读的方式显示的，而且它是显示所有分区，并不是一个分区。这个命令最方便。
[root@redhat9 root]# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda2 ext3 7.6G 2.3G 4.9G 32% /
/dev/sda1 ext3 99M 9.3M 85M 10% /boot
none tmpfs 62M 0 62M 0% /dev/shm
parted倒是有点复杂了，因为它的功能很强，redhat 9中的parted不支持-p参数，但是用parted命令进入后可以用p命令显示出当前的磁盘分区和文件系统情况：
# parted
