Hi guys,

the output of "df -k" is giving the following output.
/home (/dev/vg02/lvol2 ) : 17364312 total allocated Kb
2772080 free allocated Kb
14592232 used allocated Kb
84 % allocation used
/usr (/dev/vg00/lvol7 ) : 1471160 total allocated Kb
1034935 free allocated Kb
436225 used allocated Kb
29 % allocation used

I want as followes.
/home /usr
84 % 29 %

can some body suggest the shell script?
the script must use 'df' command ( not 'bdf').
Thnx in advance.
VB

Hi,

Try the following but you may have to adjust the printf statements to cater for the maximum length filesystem name that you have (I have allowed only 10 chars...

#!/usr/bin/sh

let NUM=0

df -k | {
while read A B C
do
if [[ ${A} = /*(?) ]];
then MP[NUM]=${A}
continue
fi

if [[ ${B} = % ]];
then PCT[NUM]=${A}
let NUM=NUM+1
continue
fi
done
}

let TOTAL=NUM

let NUM=0
while ((NUM < TOTAL));
do
printf "%10s" ${MP[NUM]}
let NUM=NUM+1
done

print

let NUM=0
while ((NUM < TOTAL));
do
printf "%9s\%" ${PCT[NUM]}
let NUM=NUM+1
done

print

exit

Regards,
John

#!/bin/ksh
echo "/home /usr"
HOM=`df -k /home|grep %|awk '{print $1}'`
USR=`df -k /usr |grep %|awk '{print $1}'`
echo "$HOM % $USR %"

Sorry my first example was for /var and /usr. But now you can compare them both and see that there isn't much to make if work for any filesystem or any number of file systems.

#!/bin/ksh
echo "/var /usr"
VAR=`df -k /var|grep %|awk '{print $1}'`
USR=`df -k /usr |grep %|awk '{print $1}'`
echo "$VAR % $USR %"

This should work for you.

How about using the following -

bdf /home /usr
