Re-reading from already read filehandle

Question

I opened a file to read from line by line:

open(FH,\"<\",\"$myfile\") or die \"could not open $myfile: $!\";
while ()
{
    # ...do something
}
         


        

Answer 1

You have a few options.

• Reopen the file handle
• Set the position to the beginning of the file using seek, as William Pursell suggested.
• Use a module such as Tie::File, which lets you read the file as an array, without loading it into memory.
