使用“column -t”命令可以用表格化方式显示输出：
举个例子：
[root@localhost /]# mount
/dev/sda3 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
/dev/sda8 on /data1 type ext4 (rw)
/dev/sdb1 on /data2 type ext4 (rw)
/dev/sdc1 on /data3 type ext4 (rw)
/dev/sda2 on /home type ext4 (rw)
/dev/sda5 on /usr type ext4 (rw)
/dev/sda6 on /var type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /sys/kernel/config type configfs (rw)
[root@localhost /]# mount | column -t
/dev/sda3 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
/dev/sda8 on /data1 type ext4 (rw)
/dev/sdb1 on /data2 type ext4 (rw)
/dev/sdc1 on /data3 type ext4 (rw)
/dev/sda2 on /home type ext4 (rw)
/dev/sda5 on /usr type ext4 (rw)
/dev/sda6 on /var type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /sys/kernel/config type configfs (rw)
[root@localhost /]#
对比之后可以发现“mount | column -t”命令输出很清晰。
