Handle bunch of lines as a Handle

shammi000 has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

How can i handle a bunch of lines as a ID or File Handle (without saving it in a temp file).

I am getting the mail contents from a db, and i need to process the entire content in my script. Some times mail contains 50K lines or more. (Including attachments).

Regards,
Shameem

Are you asking for something like `open(my $fh, '<', \$var);` [download] That will allow you to read the contents of `$var` via file handle `$fh`. By the way, please don't place your code in PRE tags. Use `<p>` at the start of paragraphs, and wrap computer text (programs, data, output, etc) in `<c>...</c>` tags.)	[reply] [d/l] [select]

`open my $fh, "<", \$e_mail or die; while (<$fh>) { # process line }` [download] Enjoy, Have FUN! H.Merijn	[reply] [d/l]

Using IO::String module we can handle a bunch of line as a file handle. --sugumar--	[reply]
