The column command is a little shell command that makes it easy to print the results in a aligned fashion.

Example 1

/dev/mapper/vg0-root  on  /              type  ext3    (rw,errors=remount-ro)
tmpfs                 on  /lib/init/rw   type  tmpfs   (rw,nosuid,mode=0755)
proc                  on  /proc          type  proc    (rw,noexec,nosuid,nodev)
sysfs                 on  /sys           type  sysfs   (rw,noexec,nosuid,nodev)
procbususb            on  /proc/bus/usb  type  usbfs   (rw)
udev                  on  /dev           type  tmpfs   (rw,mode=0755)
tmpfs                 on  /dev/shm       type  tmpfs   (rw,nosuid,nodev)
devpts                on  /dev/pts       type  devpts  (rw,noexec,nosuid,gid=5,mode=620)
/dev/mapper/vg0-home  on  /home          type  ext3    (rw)
/dev/mapper/vg0-tmp   on  /tmp           type  ext3    (rw,nosuid)
/dev/mapper/vg0-var   on  /var           type  ext3    (rw)

Example 2

cat /etc/passwd | column -t -s ":"

or

column -t -s ":" /etc/passwd

The column command supports the following options

-c      Output is formatted for a display columns wide.

-n      By default, the column command will merge multiple adjacent delimiters into a single delimiter when using
         the -t option; this option disables that behavior.

-s      Specify a set of characters to be used to delimit columns for the -t option.

-t      Determine the number of columns the input contains and create a table.  Columns are delimited with whites‐
         pace, by default, or with the characters supplied using the -s option.  Useful for pretty-printing dis‐
         plays.

-x      Fill columns before filling rows.
