Hello all:
Maybe you can help me with this:
I have 2 files, with columns for station id and depth. The first one
has 2 columns like this
'IS02-34' 1
'IS02-34' 2
IS02-34' 3
'IS02-35' 1
'IS02-35' 2
'IS02-35' 3
'IS02-37' 0
'IS02-37' 1
'IS02-37' 2

And the second one has similar structure:
'IS02-35' 1
'IS02-35' 2
'IS02-35' 3
'IS02-37' 1
'IS02-37' 2
'IS02-37' 3
'IS02-39' 0
'IS02-39' 1
'IS02-39' 2

Basically I want to find the lines on each file that both string
(station id) and depth=1 are coincdent, and extract them.
In this example, lines 4,8 from the first file, coincide with lines 1,4
from the second.
Any idea about how could I do this for 2 large files? I tried using
'where' but it doesn't like it....
Thanks
