Well, I suppose it's a matter of opinion whether that's an easy way to
solve the problem. It requires a lot of keyboard input. Here's one
which I would use. To compile, just:
$ cc stripcr.c -o stripcr
It's a filter: that is, you run it like this:
$ stripcr <infile >outfile
The reason for this isn't laziness: that way, you can pipe things into
it.

stripcr.c:
----------------------------------------------------------------------
#define LINELENGTH 8192 /* max length of program line */
#include <stdio.h>
char inbuffer [LINELENGTH]; /* read in here */
char outbuffer [LINELENGTH]; /* write from here */
int main (int argc, char *argv [])
{
while (fgetsb (inbuffer, LINELENGTH, stdin))
{
char *i = inbuffer;
char *o = outbuffer;
do
{
if (*i != '\r') /* not a CR */
*o++ = *i; /* copy it */
}
while (*i++);
fputs (outbuffer, stdout);
}
}
