This adds string-x.rst for each subcommand x of string. The main page (string.rst) is not changed, except that examples are shown directly after each subcommand. The subcommand sections in string.rst are created by textual inclusion of parts of the string-x.rst files. Subcommand man pages can be viewed with either of: ``` man string collect man string-collect string collect <press F1 or Alt-h> string collect -h ``` While `string -h ...` still prints the full help.

Synopsis

|
--------
|
|
|
|
.. BEGIN SYNOPSIS
|
|
|
|
::
|
|
|
|
string collect [(-N | --no-trim-newlines)] [STRING...]
|
|

|
.. END SYNOPSIS

Description
|
|
-----------
|
|
|
|
.. BEGIN DESCRIPTION
|
|
|
|
``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 ``string collect``.
|
|
|
|
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)``.
