Different output for script?
Good morning guys!

When I run this full script:
Code:
#!/bin/sh
echo "Please type oracle-lower case please:"
read X
if [[ "${X}" != "oracle" ]]
then
       echo "Sorry that is not oracle, try again"
       exit 1
else
       echo Thank you
fi
find / -name oracle 2>/dev/null |
while read line
do
        bdf | grep "$X" | awk 'BEGIN {total=used=free=0}
        {total +=$2
         used +=$3
         free +=$4}
 END    {print "total space for oracle: "total;
         print "free space available for oracle: "free;
         print "space already used by oracle: "used}'
done

The output is:
total space for oracle: 0
free space available for oracle: 0
space already used by oracle: 0

When I run from this point below:
Code:
find / -name oracle 2>/dev/null |
while read line
do
        bdf | grep "$X" | awk 'BEGIN {total=used=free=0}
        {total +=$2
         used +=$3
         free +=$4}
 END    {print "total space for oracle: "total;
         print "free space available for oracle: "free;
         print "space already used by oracle: "used}'
done

I get:
total space for oracle: 2.01234e+09
free space available for oracle: 5.41099e+06
space already used by oracle: 3.29016e+08
bdf: /home/auto/***: Stale NFS file handle
bdf: /home/auto/***: Stale NFS file handle

I need to run the entire script, with the correct output, but without the NFS errors?

Can anyone tell me what Ive done wrong?

In the 2nd code block, it doesn't show where $X is set. If it isn't, then the bdf is probably returning all filesystems and the grep $X is not filtering the output.

Instead of
Code:
bdf | ...

use
Code:
bdf 2>/dev/null | ...

to get rid of the errors.

jsmithstl-how woudl I correct that? I thought I set the value at the top of the script when I put $X=oracle?

How would I fix it to run the whole script correctly?

Scrutinizer-thanks!

do the below:-


Code:
#!/bin/sh
echo "Please type oracle-lower case please:"
read X
if [[ "${X}" != "oracle" ]]
then
       echo "Sorry that is not oracle, try again"
       exit 1
else
       echo Thank you
fi
find / -name oracle 2>/dev/null |
while read line
do
        bdf | grep "oracle" | awk 'BEGIN {total=used=free=0}
        {total +=$2
         used +=$3
         free +=$4}
 END    {print "total space for oracle: "total;
         print "free space available for oracle: "free;
         print "space already used by oracle: "used}'
done

Your script prompts the user to enter "oracle" and exits if any other value is typed in. Why even ask if all you'll accept is "oracle"? Eliminate the read and just do as Ahmad.diab suggests above.

Scrutinizer's suggestion above is something you should do as well.
