alternative to csplit - splitting after the pattern

Question

I want to split a file after a delimiter, not before the delimiter, which is what csplit does. I can't find anything anywhere! (Also, why would there be a tool that specifically splits before a pattern, but not one that splits after it?)

File:
a
b
c
d

split at c

output: file1:
a
b
c

file 2
d

_"I can't find anything anywhere!"_ Where exactly are you searching ? `csplit`, like all tools, has manual page. That's the first place to search - usually, the man page contains the answer... — don_crissti, Apr 26 '18 at 13:33
It does not, it only shows how to split before a pattern... @don_crissti — LizzAlice, Apr 26 '18 at 13:34
If that's from `coreutils` then your man page contains the answer. How can you even say _"It does not, it only shows how to split before a pattern"_ ??? — don_crissti, Apr 26 '18 at 13:37
also, post a testable input content and expected splitted fragments — RomanPerekhrest, Apr 26 '18 at 13:39
because the default behaviour is to split before and there is not option to change this. — LizzAlice, Apr 26 '18 at 13:40
The option is explained in the manual, if you bother reading it. — don_crissti, Apr 26 '18 at 13:43
There are only options for `up to, but NOT including` the pattern. unless I am blind, there is no option for including it. — LizzAlice, Apr 26 '18 at 13:43
yeah, it's `/REGEXP/[OFFSET]` and if you read further it says `A line OFFSET is a required '+' or '-' followed by a positive integer.` — don_crissti, Apr 26 '18 at 13:45

The syntax is /REGEXP/[OFFSET]. So given

$ cat file
a
b
c
d

then

$ csplit file '/^c/+1'
6
2

gives

$ head xx*
==> xx00 <==
a
b
c

==> xx01 <==
d
