Package: coreutils Version: 9.1-1 Severity: normal Dear Maintainer,
Consider the standard repetition:
-- >8 --
$ seq 999 | csplit - /10/1 {99}
21
271
8
8
8
8
8
400
400
400
400
400
400

csplit: ‘/10/1’: match not found on repetition 15
356
$ seq 999 | csplit - 88 {99}
252
340
352

csplit: ‘88’: line number out of range on repetition 11
128
-- >8 --
Good! POSIX agrees:
An error shall be reported if an operand does not reference
a line between the current position and the end of the file.
(the operand being /10/1 or 88, resp., as re-applied via {99}).
So why, then:
-- >8 --
$ seq 999 | csplit - /10/1 {*}

-- >8 --
The manual defines {*} as
{*} repeat the previous pattern as many times as possible
but then inconsistently uses it as
88 {∞}
/10/1 {until no more matches}
Best,
