string collect [(-N | --no-trim-newlines)] [STRING...]
string collect collects its input into a single output argument, without splitting the output when used in a command substitution. This is useful when trying to collect multiline output from another command into a variable. Exit status: 0 if any output argument is non-empty, or 1 otherwise.
If invoked with multiple arguments instead of input,
string collect preserves each argument separately, where the number of output arguments is equal to the number of arguments given to
Any trailing newlines on the input are trimmed, just as with
"$(cmd)" substitution in sh.
--no-trim-newlines can be used to disable this behavior, which may be useful when running a command such as
set contents (cat filename | string collect -N).
