Hi,
I've been thinking about this for quite some time now.
Suppose I have a text file ("mypet.log" that contains:
dog
pig
cat
Then I have another text file and I want to read it line by line and extract
each line that has those contained in the first file. Sort of like running
while inside while.
"myallpetlogs" contains:
blabla dog blah
blabla cat blah
blabla dog blah
blabla pig blah
blabla cat blah
blabla pig blah
Now, the goal is to have 3 files which contains all extracted lines in
"myallpetlogs"
1. dogs.logs
2. cat.logs
3. pig.logs
How do I assign some variable to what was returned by while loop?
Perhaps the above goal should be written like this:
open MYPETS, '<', or die $!
open PETLOGS, '<', or die $!
whileeach my $pets (<MYPETS>){
whileeach my $petlogs (<PETLOGS>){
"read each line extracting $pets and putting it in $pet.log"
"and after reading the entire PETLOGS again, go to the next pet and...
" read the PETLOGS all over again and extract the next pet??? Oh my,
I'm lost..
}
}
Any idea?
Thanks
