if you have a c compiler on your system, you can use this in a pipeline:

/*
* Copy stdin to stdout, insert formfeed every 66 lines.
*/

#include

main() {
int line = 0;
int c;

if ( (c = getchar()) == EOF)
return;

for (;;) {
if (c == '\n')
line++;
putchar(c);

/*
* An odd place to leave the loop, but it keeps a final
* formfeed from being generated when the last page
* has exactly 66 lines.
*/
if ( (c = getchar()) == EOF)
break;

if (line >= 66) {
putchar('\f');
line = 0;
}
}
}

Hi,

I would choose a perl-version:

#!/usr/bin/perl
while ()
{
chop $_;
print "$_\r\n";
}

It should be faster then C because of the very fast string-routines in perl.

Same question is in thread:

If you prefer a script, there's an answer there.
