Hi, I have a file extremely large in size and length. I want to read the
file line by line and worry about matching up each line and running that
line through a subroutine instead of opening the entire file (which would
take a while).
So how do I open a file up and process each line individually?
Well the following is traditional.
#!/usr/bin/perl
use strict; use warnings;
while (<>) { # use with >perl script_name file1 file2 ...
# do something here
# line is in default variable, $_
}__END__
Hope that helps.
James
