Do you know awk?

Hello

I'm trying to assign the line below to a variable, but I can't find the right syntax to do so.

Code:

echo $RESULT1 | awk '{print $ARG1"cm is equivalent to "$1 / 2.54"in"}'

Here is the line I tried:

Code:

DISPLAY=$(echo $RESULT1 | awk '{print $ARG1"cm is equivalent to "$1 / 2.54"in"}')

But it doesn't work.

Any help is greatly appreciated.

I can't answer the question, but I may be able to point you in the direction of a solution.

*Effective Awk Programming* is a free (as in, free but for the cost of the internet connection to download it; no other charge) postscript book.

It probably has the answer on how to assign values to variables, specifically the syntax issue.

There is another called *The GNU Awk User's Guide* that might also be helpful.
