Sorry for all the trouble
Show us the script that you are running. Like I mentioned before, the construct in VER=${line//\./} is a sh-only feature.

I could apparently see a bug being unnoticed from the answers posted above,
removing the meta-character; sorting and then displaying the last one.

the solution remains unanswered if there is a data like
3.0

version 3.0
it simply translates to 30 and no where that would be listed.

Try this one,
Code:
# !/usr/bin/ksh

ini=10000
sum=0
max=0
cnt=1
finalver=""

cal()
{
  sum=$(($sum + $1 \* $ini))
  ini=$(($ini / 10))
}

while read ver
do
ini=10000
sum=0
  echo $ver | sed 's/\./ /g' | while read v1 v2 v3 v4
  do
  if [ ! -z $v1 ]
  then
     cal $v1
     v1=""
  fi
  if [ ! -z $v2 ]
then
     cal $v2
     v2=""
  fi
  if [ ! -z $v3 ]
  then
     cal $v3
     v3=""
  fi
  if [ ! -z $v4 ]
  then
     cal $v4
     v4=""
  fi
  done
  if [ $sum -gt $max ]
  then
     max=$sum
     finalver=$ver
  fi
done < td
echo "Final Version: $finalver"
exit 0

the above one is not optimized and for sure it can be, its just a pointer to go with.

why it didnt work?
what was the output you obtained ?
what was your expected?
could you please quantify your statements?
As something that is not quantified could have many meanings derived from something that still remains abstract!!!

With your input, I had tested with my script and it works fine.

Please throw some more light!

I'll try to explain again what i m trying to do :-

I have a file in the below format :-

Quote:
test.1.0.0.1.tar.gz
test1.1.0.0.1.tar.gz
test12.1.0.0.1.tar.gz
test2.1.2.1.2.tar.gz
test23.2.0.3.1.tar.gz
test3.1.0.0.1.tar.gz
test32.1.1.1.1.tar.gz
test33.1.1.1.1.tar.gz
test34.1.1.1.1.tar.gz
test4.2.2.2.2.tar.gz
test5.1.1.1.1.tar.gz
test56.1.1.1.1.tar.gz
test8.1.1.1.1.tar.gz
NOw out of this i need to determine which is the latest version of them all. I have managed to yank of the file name "test*" and "tar.gz" from the list.

Now on the basis of version number i need to sort the latest file.

If there is any better way of doing that, Please let me know..

Your assistance is much appreciated.

test5.1.1.1.1.tar.gz
test56.1.1.1.1.tar.gz
test8.1.1.1.1.tar.gz

I guess the latest among these would be test56.1.1.1.1.tar.gz.
