So what I hope to manage to do is:

1. read in a file

2. find some entries

3. use those entries to proceed

So first I'm changing to the directory where those files are. They are into a series of folders and subfolders and I am looping (rest of script not shown) to find them all.

Then I'm checking if this file exists and, if it does, I'm opening it for read.

Then, what I want to do but I don't know how to implement it, is find the 3 entries that exist in this file. These 3 entries are space delimited and I have already initiated them as variables from before in my script. My files look like this, for example: FOLDING SHAPE OXYGEN

so I want to match those three entries (folding, shape, oxygen) using split. These three entries already correspond to variables $pattern, $cyclo and $group. In a different file, these 3 entries might have different values, so that's why I can't match the actual words "folding" and so on.

chdir "$results$filepath" or print "cannot chdir to $results$filepath 
+! $!";
 
 if (-e "test.txt") {
 open (my $test, '<', "test.txt") or print "Can't open file: $!";

    while(my $line = <$test>){
      chomp $line;
      split(" ", $line);
      print $line;
    }
}

Obviously this is wrong. I get the message I think I need to find a way to say "split those entries and put them in those three variables", but I don't know how? Anyone can suggest how to proceed?

In reply to split file and put contents in variables? by angela2
