csplit - Split a file into sections determined by Context

`xx02',.., and output byte counts of each piece to display.

3rd 40-79 and 4th 80-EOF.

$ csplit myfile 10 10 80 -- Zero length file will be create for the
2nd parameter..

$ csplit -z myfile 10 10 60 -- Same as above. But Zero length file
will NOT created

$ csplit myfile /Midas/ -- Copy upto, but not the matching line and
remaining in 2nd file.

$ csplit myfile /Midas/+6 -- Copy upto the matching line + 5 and
remaining in 2nd file.

$ csplit myfile /Midas/-6 -- Copy upto the matching line - 6 and
remaining in 2nd file.

$ csplit myfile /Midas/ {3} -- Repeat the previous pattern for 3
more times.

$ csplit myfile /Midas/ {*} -- Repeat the previous pattern as many
times as possible.

$ csplit myfile %Midas% -- skip upto, but not the matching line.
