Hi.  I am trying to split an ASCII file on the page break character,
w/o success.  If I run "awk searchstring filename" then on stdout the
lines listing the searchstring appear.  I tried re-setting the RS
variable, but didn't get the expected results.  When I tried "awk
`RS=??` searchstring filename" where ?? was 0x0C, ^M, \f and a few
others, I either recieved no output, or the entire file.

I also triedv "awk '/^M$/ && on == 1 {exit} on == 1 {print} /^M$/
{on=1}' searchstring filename" with similar results.

Could someone please help.  The end goal is to read in the file,
search for the string, and only print out the page(s) containing the
searchstring.

Thanks
Kevin

isn't that RS should be either a character or a regular expression?

so... maybe something like /[yourcharacters]/ could do...
i don't know... please have a try
cheers
