Redirection is mostly the same in Eshell as it is in other command
-shells. The output redirection operators @code{>} and @code{>>} as well
-as pipes are supported, but there is not yet any support for input
-redirection. Output can also be redirected to Elisp functions, using
+shells. The output redirection operators @code{>} and @code{>>} as
+well as pipes are supported, but there is not yet any support for
+input redirection. Output can also be redirected to buffers, using
+the @code{>>>} redirection operator, and Elisp functions, using
virtual devices.
+The buffer redirection operator, @code{>>>}, expects a buffer object
+on the right-hand side, into which it inserts the output of the
+left-hand side. e.g., @samp{echo hello >>> #<buffer *scratch*>}
+inserts the string @code{"hello"} into the @code{*scratch*} buffer.

@var{eshell-virtual-targets} is a list of mappings of virtual device
names to functions. Eshell comes with two virtual devices:
@file{/dev/kill}, which sends the text to the kill ring, and
@code{function} may be either a lambda or a function name. If
@code{mode} is nil, then the function is the output function; if it is
non-nil, then the function is passed the redirection mode as a
-symbol--@code{overwrite}, @code{append}, or @code{insert}--and the
-function is expected to return the output function.
+symbol--@code{overwrite} for @code{>}, @code{append} for @code{>>}, or
+@code{insert} for @code{>>>}--and the function is expected to return
+the output function.
The output function is called once on each line of output until
@code{nil} is passed, indicating end of output.
