Hi Dave,

you are correct Dave, your theme will work in all areas. Here just i want to compare two files.

Thanks,
Venkat

Hi Venkat,

Then Junior helpers advice in Post #10 and his subsequent corrections will do that.

Regards

Dave

VenkatReddy786,
I experienced one notable pitfall though: The script will work good and reliably on filesystems with unique names, thus the message before that grep command should be Missing *unique* filesystems:.

If non-unique filesystems are missing, the if statement (the diff command, to be exact) WILL detect that, but the grep command will not report it.

In your "real-world" output the only non-unique filesystem is swap. If you don't care for swap, it's OK, but you could face a situation where the "missing filesystems list" is empty. Another variation could be one reported filesystem with unique name but in fact another one filesystem with non-unique name is missing at the same time and not listed. Thus adding following lines after the grep command could be very useful, just in case:

Code:

echo "List of non-unique filesystems in df.pre:"
sort df.pre | uniq -dc
echo "List of non-unique filesystems in df.post:"
sort df.post | uniq -dc

It should be easy to spot potential different counters.

can you post df -k , to see how the output looks like.
