Serene,
That really looks like 'awk' code. Where did you find the code?
In a TCL script? Was it in something like this:
exec awk { $3 / ($5 * $1) }
?
Awk is a programming language (usually just on Linux/Unix) that very
easily allows you to handle data. It functions on one line of data at a
time and breaks things into columns. Each column is assigned a variable
name that is used
to refer to that column. You don't have to declare variables; it is
automatically done. You can output to a file or to the screen. You can
run awk separately (i.e. it does NOT have to be contained inside a TCL
script, you can run it at a command prompt).
If you input line of data was:
4.5 100 22 tcp 9.4532 45 1000 .0054
Then the above line of code you gave would mean:
(3rd column) / (5th column * 1st column)
Or
22 / (9.4532 * 4.5)
I hope that helps; it is the best I can do with the limited information
supplied.
