You can also change the record separator. The record separator is the character that perl uses to decide how much data to take in at once.

It is accessed with the special variable $/ and the default value is \n.

Some examples:

$/ = "\n"; #default value
$file=<DATA>; #gets one line
@file=<DATA>; #gets all lines, each line in one value
print "$file\n\n";
print join "|", @file;
__DATA__
1,2,3
4,5,6
7,8,9
[download]

prints:

1,2,3


4,5,6
|7,8,9
[download]

While but if you set $/ = ","; you get:

1,

2,|3
4,|5,|6
7,|8,|9
[download]

Note that in the second example, "3\n4," is a record.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
