Hi Guys,
I have an array in which each element is a line commandline data. It looks
something like this -
@Array contains lines:
post1: -r [EMAIL PROTECTED] -x cat-100 -h post1
post2: -x tel -h post2
post3: -h post3 -x hifi
And so on. The order of the options varies, and there may or may not be a
-r $arg on the line.
These lines are parsed from a file with more lines, of which I extracted all
the lines with -h:
open (F, "<$File");
while (<F>) {
if ($_ =~ / -h /) {
# remove crud
s/ \"\|//;
s/\/some\/crud\/path argument //;
s/\"$//;
# store what's left
push @Array, $_;
}
}
What I really need to do is build a relationship between the first field
(which is the same as the argument to -h) and the argument to -x. The -x flag
can be dropped, as they're not needed.
So it looks like I need to build a hash based.
But I can't can't grok how to parse each line out to do what I need, then
move on to the next line (all lines are unrelated to each other).
I've been using shift, but then I'm doing something like, (psuedo code):
if ($_[0] eq "-r") { $r = (shift);}
but if sub 0 doesn't eq -r, and I shift until I get to -x, say, and use that
for the $x = (shift), how can I be efficient to check again for -r, which I
still haven't found?
Is this making any sense?
Thanks,
deb
