from what it looks like you are doing, you are going through a html or cgi and replacing the '\n' in the perl script to <br>.
I have a file called cold.pl contents are:
print "I really can’t stay (Baby, it’s cold outside)\n";
print "I’ve got to go ‘way (Baby, it’s cold outside)\n";
print "The evening has been (I’ve been hopin’ that you’d drop in)\n";
print "So very nice (I’ll hold your hand, they’re just like ice)\n\n";
print "My mother will start to worry (Hey beautiful, what’s your hurry)\n";
print "And father will be pacing the floor (Listen to that fireplace roar)\n";
print "So really, I’d better scurry (Beautiful, please don’t hurry)\n";
print "Well, maybe just a half a drink more (Put some music on while I pour)\n";
When I run this script:
while($this = <>) {
$this =~ s/\\n/<br>/gi;
print $this;
}
like this:
waht.pl cold.pl > what.txt
the output in what.txt is:
print "I really can’t stay (Baby, it’s cold outside)<br>";
print "I’ve got to go ‘way (Baby, it’s cold outside)<br>";
print "The evening has been (I’ve been hopin’ that you’d drop in)<br>";
print "So very nice (I’ll hold your hand, they’re just like ice)<br><br>";
print "My mother will start to worry (Hey beautiful, what’s your hurry)<br>";
print "And father will be pacing the floor (Listen to that fireplace roar)<br>";
print "So really, I’d better scurry (Beautiful, please don’t hurry)<br>";
print "Well, maybe just a half a drink more (Put some music on while I pour)<br>";
Is this what you are looking for?
Here is a sample script that should do what you want (change end-of-line characters to <br>EOL)
#!/usr/bin/perl
use warnings;
use strict;
while(my $line = <>)
{
$line =~ s/[\r\n]+/<br>\n/g;
print $line;
}
Example of using this script:
(Without the script)
echo -e "1\n2\n3\n4\n5\n"
1
2
3
4
5
(With the script)
echo -e "1\n2\n3\n4\n5\n" | ./test.pl
1<br>
2<br>
3<br>
4<br>
5<br>
