Help cheyyandi .. I know how it feels to not have answers at the right time and right place... is Avamar a rarest of the rare kind of technology?

the PM has all external links to other websites... and nothing from what I can help but questions and informational issues information .. anyways here it is for you Sir...

Honestly, I do not know, what Avamar means// does // is

I hope the above links might help for sure....

one more suggestion... try looking at the people who posted on stackoverflow and try posting some questions there

I know, am kind of giving all time waste suggestions, but I just wish I knew the technology well enough to assist

This shows you how to do text extractions and manipulation in quite a bit of detail. We will basically extract the versions from the candidate files in /ava/repo and convert them into a number that can be used for comparison using the formula:

AVAMAR_INSTALLED_MAGIC=$((1000000 * $AVAMAR_INSTALLED_VER_MAJ + 10000 * $AVAMAR_INSTALLED_VER_MIN + $AVAMAR_INSTALLED_VER_REL))

We will use this numerical form to first figure out the latest version we have in /ava/repo and then compare that to the version we have installed to see if we want to replace it.

So here we go:

THIS IS COMPLICATED

First the whole thing:

AVAMAR_CANDIDATE=$(ls -1 /ava/repo/AvamarClient* | \
sed -e 's/.*/&:&/' \
-e 's/-[0-9]*-x86_64//1' \
-e 's/AvamarClient-//' \
-e 's/\./:/1' -e 's/\./:/1' | \
awk -F: '{ print 1000000 * $1 + 10000 * $2 + $3 " " $4 }' | \
sort -n | tail -n1 )

So let's look at what's happening. We assume that we have more than one copy of a candidate in the repo.

We list all the files in /ava/repo and pipe it to a sed + awk script that figures out their version numbers and sorts them so that the last one is the LATEST one.

Let's look at each part

SED

step 1:

-e 's/.*/&:&/'

Creates two copies of the name separated by a :. (We'll cut apart the first one and reduce it to just the version number using step 2 and 3. keep the second one intact for the rpm command to be used later)

step 2:

-e 's/-[0-9]*-x86_64[^:]*//1'

get rid of the word -NNN-x86_64.rpm from the first copy of the file names to be precise get rid trailing bits leading up to the : we inserted in earlier (but not the colon).

step 3:

-e 's/AvamarClient-//'

get rid of the word AvamarClient- from the first copy of the file names

step 4:

-e 's/\./:/1' -e 's/\./:/1'

Converts the . in JUST the extracted version numbers to :

So for example:

ls -1 /ava/repo/AvamarClient-6.4.200-400-x86_64.rpm | sed -e 's/.*/&:&/' -e 's/-[0-9]*-x86_64[^:]*//1' -e 's/AvamarClient-//' -e 's/\./:/1' -e 's/\./:/1'

would output:

6:4:200:AvamarClient-6.4.200-400-x86_64.rpm

AWK

Now to convert the extracted version to something magical we push that through awk: where -F:splits the string above using : as the delimiter. So $1 = MAJ, $2 = MIN, $3 = REL, $4 = Filename; for example above it would be $1 = 6; $2 = 4; $3 = 200; $4 = AvamarClient-6.4.200-400-x86_64.rpm

So we apply our magic formula and print the filename in awk:

'{ print 1000000 * $1 + 10000 * $2 + $3 " " $4 }'

so for above example it would output:

6040200 AvamarClient-6.4.200-400-x86_64

And voila we have a magic comparable number

SORT and TAIL

Since we may have more than one file in our repo, the above will be a list of them and because we have the magic number we can use it to get the latest one. Use sort -n to sort and use tail -n1to grab the very last one (sort is ascending order).

So now in AVAMAR_CANDIDATE we would have 6040200 AvamarClient-6.4.200-400-x86_64

Let's make life easier and put this into two variables:

AVAMAR_CANDIDATE_FILE=$(echo $AVAMAR_CANDIDATE | cut -f2 -d' ')
AVAMAR_CANDIDATE_MAGIC=$(echo $AVAMAR_CANDIDATE | cut -f1 -d' ')

Let's do the same with the installed version:

AVAMAR_INSTALLED=$(rpm -qa | grep AvamarClient)

AVAMAR_INSTALLED_MAGIC=$(echo $AVAMAR_INSTALLED | \
sed -e 's/^AvamarClient-//' \
-e 's/-[0-9].*x86_64$//' \
-e 's/\./:/g' | \
awk -F: '{ print 1000000 * $1 + 10000 * $2 + $3 }' )

Now all you have to do is compare the value of the two magic numbers:

if [ $AVAMAR_INSTALLED_MAGIC -lt $AVAMAR_CANDIDATE_MAGIC ] ; then
rpm -ivU /ava/repo/$AVAMAR_CANDIDATE_FILE
fi

I hope that this will get you to learn shell scripting as it is an amazingly powerful tool.
