[Wolves] Sed help.

[chris procter]

If your awking you can do:

awk 'BEGIN{i=""}{print "start " $0 "|grep -vir >
'http://' >> test" i ".txt"; i++}' < in.txt > out.txt

(replacing start with your start text obviously) 
which will produce test.txt test1.txt etc

or the simpler

awk '{print "start " $0 "|grep -vir > 'http://' >>
test" $NR ".txt"}' < tmp.txt

which will produce test1.txt test2.txt etc (i.e. the
first file has a number)

In awk $0 is the current line $NR is the number of the
current line.

I like awk, its far nicer then sed :)
