Help to make the script simple

Shell Programming and Scripting

Hi All,

I have a script which throws the output if condition matches. I run the cmd :

# ldf
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c1t0d0s0    1984564 1375019  550009    72%    /
/dev/dsk/c1t0d0s3    5040814 2628410 2361996    53%    /usr
/dev/dsk/c1t0d0s5    1984564  815790 1109238    43%    /var
/dev/dsk/c1t0d0s6    12096820 8579296 3396556    72%    /home1
/dev/dsk/c1t0d0s7    8265819 6076332 2106829    75%    /home2
/dev/dsk/c1t0d0s4    5040814 3965027 1025379    80%    /opt

Now I want to get the output only of those partitions whose used space is more than 70%. The below script works:

---------------------------------------------------------------------

#!/bin/bash
rm -rf /deepak/out.txt 
var=1
max=`ldf | awk 'NR>1' | awk '{print $5}' | cut -b1-2 | wc -l`
while [ $var -le $max ]
do
val=`ldf | awk 'NR>1' | awk '{print $5}' | cut -b1-2 | sed -n "${var}p"`
if [ $val -ge 70 ]
then
dir=`ldf | awk 'NR>1' | awk '{print $6}' | sed -n "${var}p"`
echo " $dir = $val%" >> /deepak/out.txt
fi
var=`expr $var + 1 `
done

-----------------------------------------------------------------------

I know, this task can be done by much simple way. Can anyone suggest?

Thanks,
Deepak Tiwari

please use code tags when you post code or outputs from a command. it's much easier to read!

Replace the "cat example.txt" with your ldf command

$ cat example.txt
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c1t0d0s0    1984564 1375019  550009    72%    /
/dev/dsk/c1t0d0s3    5040814 2628410 2361996    53%    /usr
/dev/dsk/c1t0d0s5    1984564  815790 1109238    43%    /var
/dev/dsk/c1t0d0s6    12096820 8579296 3396556    72%    /home1
/dev/dsk/c1t0d0s7    8265819 6076332 2106829    75%    /home2
/dev/dsk/c1t0d0s4    5040814 3965027 1025379    80%    /opt
$
$ cat example.txt | awk '$5~/(1|)[7-90].%/'
/dev/dsk/c1t0d0s0    1984564 1375019  550009    72%    /
/dev/dsk/c1t0d0s6    12096820 8579296 3396556    72%    /home1
/dev/dsk/c1t0d0s7    8265819 6076332 2106829    75%    /home2
/dev/dsk/c1t0d0s4    5040814 3965027 1025379    80%    /opt

Try

ldf |awk '{if ( $5 >= 70 ) print $5," " $6 }'
