oneline — delete everything after first null or newline character, effectively "onelining" the input
The filter deletes everything after the first null (\0
)
or newline (\r
or \n
) character.
Effectively, it only preserves and returns the first line of input.
For more information on Perl Regular Expressions, pattern matching and character classes, see perlre(1).
