Depends on how big and what format you require.

One way is to put the contents of the file into an array, write your first line(s), then spit the array afterward. Example (yeah I'm skipping strict, warnings, errorcodes, and other good programming practices):

open (GB,"$bookfile");
@oldstuff = <GB>;
close GB;
open (FILE,">$newfile");
print FILE "pre-pendings here\n";
print FILE "@oldstuff";
close FILE;
# rename file if necessary

Another way is to write your pre-pending content to a file, then stream (is this the right word) the old file contents. In other words:

open (FILE,">$newfile");
print FILE "pre-pendings here\n";
open (GB,"$bookfile");
while (<GB>) {
     print FILE "$_";
}
close GB;
close FILE;
# rename file if necessary

and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
