How would you use csplit to segment a text file by each 100th
occurrence of a string of characters?

You can't. I assume the "too many file" is from awk. Show us your code
now you've updated it as I suggested and tell us which version of awk
you're running.

Thanks for the quick response. I don't need to use egrep. I was just
under the impression that it was the best method.
I tried using your method, but awk keeps on bombing out due to the
following error:
awk: too many output files 10
record number 1000
This is what I have:
awk '/"=============================="/
{c++; if (c==100) {fn++; c=0}}
{print > filename_segments"."fn}' fn=0 filename

filename_segments is an undefined variable, so this will just generate a
bunch of hidden files (i.e. ones that start with "."). he version I
posted used your original file name as a base. If you want to use
"filename_segments" as a base, then put it in the double quotes around ".".
As for too many files, try throwing in a "close()" within the "if"
clause to close the previous one before you open a new one.
By the way, if you're not using it already - I recommend using "gawk"
as your awk.

No, it'll print the whole file, segmented.

awk could do this easily, e.g. (untested):
awk '/***********************************/{c++;if (c==100){fn++;c=0}}
{print > FILENAME "." fn}' fn=0 file
Do you really need to use egrep?
