Got great help earlier, now have a couple of questions.

QUESTION #1

file1 data:

# This is a list of selected nets
Net 'GROUND' top side
Net 'GROUND' bottom side
Net '/ad1'   top side
Net '/ad1'   bottom side
Net '/VCCA'  top side
Net '/VCCA'  bottom side

[download]

a. I need to seek all lines that has the word "Net" in file1

b. remove lines that contain duplicates found in the 2nd column only, so that it outputs to file called "file2" to look like below:

'GROUND'
'/ad1'
'/VCCA'

[download]

Question #2

How can I take a file like "file2" and have perl read the column and strip out any lines in another file that are contained in the file2 listing?

While I have similar scripts written in UNIX (Korn), I'm trying to learn PERL's eqivalent code.

Thanks... RCP
