[SOLVED] Auto Disk Space Checking Script.

Hi gnashley

Code:

       12                              3   4                  56
conv1=((cat test.txt | awk '{print $1}') / (1024 * 1024 * 1024))

above shows that 1 and 6 are external opening and closing paranthesis

while 2 and 3 --- and 4 and 5 are internal paranthesis.

i think i am not missing the paranthesis

Hi gnashley

Code:

       12                              3   4                  56
conv1=((cat test.txt | awk '{print $1}') / (1024 * 1024 * 1024))

i think parenthesis are even.

Hi Guys

Here is the final script...

i was unable to convert the KBs to GBs in a single line as discussed in above replies..

so i dealt it with below code

Code:

#!/bin/sh

df |awk '{ print $4 "\t" $6 }'|grep -v -e shm -e boot > sp.txt

cat sp.txt | grep -v -e Avail -e oracle_home > sp1.txt

sed '1d' sp1.txt > sp2.txt

while read inputline
        do
                echo $inputline > test.txt
                input=`cat test.txt |awk '{print $1}'`
                if [[ $input -lt 52428800 ]]
                then
                conv1=`cat test.txt | awk '{print $1}'`
                ((mega=$conv1/1024))
                ((giga=$mega/1024))
                echo "Mount point `cat test.txt|awk '{print $2}'` has "$giga" GB"
                else
                conv2=`cat test.txt | awk '{print $1}'`
                ((mega=$conv2/1024))
                ((giga=$mega/1024))
                echo "inside else"
                echo "Mount point `cat test.txt|awk '{print $2}'` has "$giga" GB"
                fi
done < sp2.txt

Any help to shorten above code will be greatly appreciated.

Regards

Hi Guys a more refined version of above script is as follows.

Code:

#!/bin/sh

df |awk '{ print $4 "\t" $6 }'|grep -v -e shm -e boot > sp.txt

cat sp.txt | grep -v -e Avail -e oracle_home > sp1.txt

sed '1d' sp1.txt > sp2.txt

if [ -e  output.log ]
then
        rm -rf output.log
else
        echo "file does not exists"
fi


while read inputline
        do
                echo $inputline > test.txt
                input=`cat test.txt |awk '{print $1}'`
                if [[ $input -lt 52428800 ]]
                then
                conv1=`cat test.txt | awk '{print $1}'`
                ((mega=$conv1/1024))
                ((giga=$mega/1024))
                        if [[ $giga -eq 0 ]]
                        then
                        echo "Mount point `cat test.txt|awk '{print $2}'` has "$mega" MB available space" >> output.log
                        else
                        echo "Mount point `cat test.txt|awk '{print $2}'` has "$giga" GB available space" >> output.log
                        fi
                else
                conv2=`cat test.txt | awk '{print $1}'`
                ((mega=$conv2/1024))
                ((giga=$mega/1024))
                echo "inside else"
                echo "Mount point `cat test.txt|awk '{print $2}'` has "$giga" GB available space"
                fi

done < sp2.txt
