UNIX for Advanced & Expert Users

One question for clarification: Do you want to test 2 filesystems (/export and /home/t2) or one (/export/home/t2)?

Put this line in the head of your script

Code:

set -x

and start it again. Then put the output here.

Just another dude chiming in to help.

Code:

#!/bin/sh
set -x # turn on execution trace
warninglimit=350000
lowlimit=250000
filesystems="/export /home/t2/"
for fs in $filesystems
do
    # try the df separately and catch any errors
    dfoutput=`df -k $fs`
    if [ $? -ne 0 ] ; then
        echo "Error running 'df -k $fs', skipping" >&2
        continue
    fi
    size=`echo $dfoutput |grep $fs|awk '{ print $4; }'`
    if [ "$size" -le $lowlimit ]
    then
        echo mailx -s "URGENT: Low disk space for $fs ($size)" -r abc@sd.com
        # why do you want to stop
        # why not keep going?
        break
    fi
    if [ $size -le $warninglimit ]
    then
        echo mailx -s "WARNING: Low disk space for $fs ($size)" -r abc@sd.com
    fi
done

One thing I'll point out, notice the added double quotes around $size in the following line. This is another way to suppress the 'test' error messages you got, but it really just avoids the problem of the 'df' failing.

Code:

if [ "$size" -le $lowlimit ]

Hi All,

Thanks a lot for your suggestions.

I tried implementing the last one ,but it is still throwing an error while doing export.
I noted one thing very peculiar here,that it is not allowing me to export but it is still displaying the QUOTA of the environment.

Found it really strange.

Any suggestions/comments??

Thanks..

Ok, try this one:

Code:

df -k | grep \/export

Show the output please.

@qneill
Just tried it out - you get no error when issuing df for a filesystem you don't have any rights for. I am about to see it exists at all on his system.

Hi ,
It didn't return any output.....

No output? Should come at least some error text. Anyway it seems you even don't have a filesystem with the mount point /export
Can you confirm this?
