I am new to perl as of a couple weeks ago.

If it's easy, I would like to truncate an html file that I'm continuously adding one line of information to the top of. I would like to keep this file just 5 "lines" long. Lines are separated by an html line break in this case, not a new line character.

The html file is text only with no tags or formatting and completely empty at the start of the process.

New lines are added to the file such that $html_doc = "a new set - line 1 {br} $html_doc"

After 6 additions to the file, it looks like: (note: curly brackets are used below instead of < and > to illustrate)

a new set - line 6 {br}a new set - line 5 {br}a new set - line 4 {br}a new set - line 3 {br}a new set - line 2 {br}a new set - line 1

in a browser the file looks like:
a new set - line 6
a new set - line 5
a new set - line 4
a new set - line 3
a new set - line 2
a new set - line 1

I would like to use the simplest way to chop off anything past the 5th line break, IF there are that many lines. Otherwise, the entire file can stay as is.

Is there an easy way to do this?
