Objet: Re: Need help comparing lines in two files
Lets say file 1 is:
foo
bar
... continues on for 100 lines
And file 2 is:
foo
baz
bar
... continues on exactly the same 100 lines as file 1
Would file 2 be different from file 1 from line 2 and down? Or would it
be different for line 2 and 3?
Also, the keywords:
next; Brings you to the next iteration in a loop
last; leaves the loop
Should help you iterate through a while loop (or empty loop)
i.e.
{
# this is a loop, just two sets of brackets
# put a last statement and it will leave.
# put one of these in your for loops, or outside of your for loops.
}
Also you can get tricky by naming loops, i.e.:
FOO:
{
print "foo";
BAR:
{
last FOO;
}
# anything below here never executes
print "bar";
}
