Subject: RFE: more dynamic df output format
Date: Mon, 06 Sep 2010 10:17:45 -0500

 Hey all,

This is not a bug as much as a request to make the df output more 
flexible/dynamic and readable.

Basically, there are two types of output now:
  *Historic representations of drives:

$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda2             15235072  10537884   3910808  73% /
/dev/hda6              2030736    310444   1615472  17% /var
/dev/hda5            454700584  26684920 404545504   7% /export
/dev/hda1               101086     21551     74316  23% /boot
tmpfs                   712740         0    712740   0% /dev/shm
---

  *And those with the same output field widths and longer names:

vault://share/linux  960301960 315005712 645296248  33% /mnt/linux
vault://share/fileshare
                     960301960 315005712 645296248  33% /mnt/fileshare
vault://share/Public 960301960 315005712 645296248  33% /mnt/public
vault://share/win    960301960 315005712 645296248  33% /mnt/win
vault://share/apps   960301960 315005712 645296248  33% /mnt/apps
vault://share/backup 960301960 315005712 645296248  33% /mnt/backup
vault://share/keep-forever
                     960301960 315005712 645296248  33% /mnt/keep
vault://share/builds 960301960 315005712 645296248  33% /mnt/builds
vault://share/Qdownload/training
                     960301960 315005712 645296248  33% /mnt/training

This is also true of volume group output:
$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/vg_power-lv_root
                      51606140   8271456  40713244  17% /
tmpfs                  2513156       808   2512348   1% /dev/shm
/dev/sda1               495844     64352    405892  14% /boot
/dev/mapper/vg_power-lv_home
                      94697324   8814368  81072616  10% /home
/dev/sdb1            480719056 166757848 289542008  37% /storage
---

The output could be cleaned up to look like this:
$ df
Filesystem                     1K-blocks       Used   Available  Use%   
Mounted on
/dev/mapper/vg_power-lv_root    51606140    8271456    40713244   17%   /
tmpfs                            2513156        808     2512348    1%   
/dev/shm
/dev/sda1                         495844      64352      405892   14%   
/boot
/dev/mapper/vg_power-lv_home    94697324    8814368    81072616   10%   
/home
/dev/sdb1                      480719056  166757848   289542008   37%   
/storage

Slightly more read-able.

Here's the requested 'stuff':

df -P does what you want I think.
We're also working on better aligning the columns given
variable heading and content widths.

cheers,

 Close, but still kinda ugly...

# df -hP
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/sysvg-root   49G   16G   31G  34% /
/dev/mapper/sysvg-data  348G   11G  319G   4% /export
/dev/mapper/sysvg-backup   49G  6.0G   40G  14% /backup
/dev/mapper/sysvg-var  4.9G  767M  3.9G  17% /var
/dev/sda1             122M   19M   97M  17% /boot
tmpfs                 7.9G     0  7.9G   0% /dev/shm

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/sysvg-root
                       49G   16G   31G  34% /
/dev/mapper/sysvg-data
                      348G   11G  319G   4% /export
/dev/mapper/sysvg-backup
                       49G  6.0G   40G  14% /backup
/dev/mapper/sysvg-var
                      4.9G  767M  3.9G  17% /var
/dev/sda1             122M   19M   97M  17% /boot
tmpfs                 7.9G     0  7.9G   0% /dev/shm


Looking for something a little cleaner, like this:
# df
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/sysvg-root    49G   16G   31G  34% /
/dev/mapper/sysvg-data   348G   11G  319G   4% /export
/dev/mapper/sysvg-backup  49G  6.0G   40G  14% /backup
/dev/mapper/sysvg-var    4.9G  767M  3.9G  17% /var
/dev/sda1                122M   19M   97M  17% /boot
tmpfs                    7.9G     0  7.9G   0% /dev/shm
