Help with new output of "df"

[Supp0rtLinux]

I used Geektool extensively and one of my scripts does a "df -h", but excludes a few local volumes so it only shows the main HD and any mounted USB/firewire volumes. I just rolled up to the ML GM and I now when running a "df" I now see columns for "iused", "ifree" and "%iused". You used to have to specify the -i flag to see this. According to the man page, this is now default and the result is that the extra columns are skewing my Geektool layout. I want to exclude them. I know I can do so with awk or cut. However, doing so with either drops the formatting. Example:

stimpy:~ adavis$ df -h|grep -v devfs|grep -v "map"|grep -v "localhost"|grep -v "Boot OS X"|grep -v "Recovery HD"
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk1 476Gi 195Gi 280Gi 42% 51312849 73422228 41% /
/dev/disk3s2 186Gi 8.8Mi 186Gi 1% 0 0 100% /Volumes/SHARED
/dev/disk3s1 410Gi 211Gi 199Gi 52% 55367029 52087612 52% /Volumes/PortableHFS
/dev/disk5 465Gi 134Gi 331Gi 29% 35208278 86726563 29% /Volumes/Time Machine (Work)
/dev/disk6s2 400Gi 201Gi 199Gi 51% 52687032 52086588 50% /Volumes/Documents (Encrypted)

stimpy:~ adavis$ df -h|grep -v devfs|grep -v "map"|grep -v "localhost"|grep -v "Boot OS X"|grep -v "Recovery HD"|awk '{print $1, $2, $3, $4, $5, $9}'
Filesystem Size Used Avail Capacity Mounted
/dev/disk1 476Gi 195Gi 280Gi 42% /
/dev/disk3s2 186Gi 8.8Mi 186Gi 1% /Volumes/SHARED
/dev/disk3s1 410Gi 211Gi 199Gi 52% /Volumes/PortableHFS
/dev/disk5 465Gi 134Gi 331Gi 29% /Volumes/Time
/dev/disk6s2 400Gi 201Gi 199Gi 51% /Volumes/Documents

… and using cut has similar results...

Anyone have any clues as to how to strip the inode info off the output of "df" without dropping the formatting of df? I want the output and formatting and all columns except the three "i" columns of inode info.

I just ran into the same issue last night after installing ML, but I am not using GeekTool for the output display - Just in an overnight script.

I fixed the DF issue by using the below Bash Script, this will output the DF output to a file in your home directory called CutDF.txt which you could monitor this file in GeekTool. Just setup the script to run from CRON on a timed interval.

-------- Script Start

#!/bin/sh

TmpDF=$(mktemp /tmp/$(basename $0).$$.XXXXXX) || exit 1
DisplayCutDF=$HOME"/CutDF.txt"

/bin/df -h | grep -e ^Filesystem > "$TmpDF"
IFSOLD=$IFS
IFS=$'\n'
HRDFHold=($(<"$TmpDF"))
IFS=$IFSOLD

for (( a=0; a<${#HRDFHold[@]}; a++)); do
HRDFLine=${HRDFHold[$a]:0:43}${HRDFHold[$a]:69$((${#HRDFHold[$a]}-69)))}
echo "$HRDFLine" > $DisplayCutDF
done
unset HRDFHold

/bin/df -h | grep -e ^/dev/ | sort -k 9 > "$TmpDF"

IFSOLD=$IFS
IFS=$'\n'
HRDFHold=($(<"$TmpDF"))
IFS=$IFSOLD

for (( a=0; a<${#HRDFHold[@]}; a++)); do
HRDFLine=${HRDFHold[$a]:0:42}${HRDFHold[$a]:68$((${#HRDFHold[$a]}-68)))}
echo "$HRDFLine" >> $DisplayCutDF
done
unset HRDFHold
rm "$TmpDF"

--------- Script End

Attached is the script in TXT file, change extension to .sh and a sample output.

Hope this helps,

Tom.

Umm... take another look at the output of 'man df'!

For your convenience, I draw your attention to the bolded bit of a line from the man page:

-i Include statistics on the number of free inodes. This option is now the default to conform to Version 3 of the Single UNIX Specification (``SUSv3'') Use -P to suppress this output.

BTW, I have this in my .bashrc; I find I never care about /dev, /net or /home.

df () { /bin/df -Pk $* | grep "Filesystem\|disk\|Volumes"; /bin/df -Phn $* | grep "Filesystem\|disk\|Volumes"; }

(Come to think of it, perhaps grep --v "dev\|net\|home" would be safer...)

I did look at 'man df'. The problem is that when you use the -P option, you lose the friendly rounding to the nearest Mb, Gb, Tb, etc and are shown everything in blocks. The goal is to see the df output with the benefits of "-h", but not see the inode info by using "-P". The two don't seem to work together for the desired result. See below:

So perhaps instead of telling us to look at "man df" and pointing out the -P option that you ASSumed we missed, instead you should actually run the command yourself and realize you're just wasting bits with your typing.

I probably don't deserve to be in this technical thread, but I played around.

Does df -Ph work as opposed to df -h -P?

Works for me.

Works for me as well. So does "df -P -h". Thanks much. Who knew that switching the order would make the difference.

I'm guessing it sets the flags as it gets to them, overriding any previous ones that are conflicting. So if you set the -h flag first, the -P overrides it with it's default options. When you do it the other way around, -h only overrides the conflicting parts of the -P command, so you get what you're looking for from both.

It seems Supp0rtLinux didn't see the import of this part of my previous post " /bin/df -Phn "

Supp0rtLinux ASSumed I didn't use the command I obviously use use so often I've written a shell function to make it work better.

I believe Supp0rtLinux saw the documentation of the -P option and chose not to mention it. Others wouldn't be so charitable.
