I'm a new programmer in Perl. I have a ascii file with 20000 records. How i can make searches inside this file with one or two fields. Which are the steps?
May i have a simple example of this type of program.
Thank you

Is each line of the file divided into fields?
If so, what is used to separate the fields?

Here is an example where the fields are separated with a '|' character.
Assume you want the first field to be "Person" and the third field to be "Every month":

$Record0Search = "Person";
$Record2Search = "Every month";

open(FILE, "data.txt");
while ($Line = <FILE>) {
   @Fields = split '\|', $Line;
   print $Line if (($Fields[0] eq $Record0Search) && ($Fields[2] eq $Record2Search));
}
