Extract lines from a file automatically. Please a Help

alexcol · #1 (**permalink**) 12-16-2006

hello, hope you can help me:
ive got a file called archivos

The content or structure of this file is

./chu0/filechu
./chu1/filechu

I extract each line from this file manually and redirect to a file, and it Works fine, so the command line is:

awk ‘/chu0/ {print $0}’ < archivos > portal0
awk ‘/chu1/ {print $0}’ < archivos > portal1

The problem is to extract these lines automatically, an i dont know how to do this, with a loop for example.

and i tried but gets some error whit this command

i=0
while (i<=num)
do
awk –v i=$i ‘ /chu$i/ {print $0} < archivos > portal$i
done

how can i do that so i can extract lines from this file automatically?can you help me? please.
