Function: eshell-send-input

eshell-send-input is an interactive and byte-compiled function defined in esh-mode.el.gz.

Signature

(eshell-send-input &optional USE-REGION QUEUE-P NO-NEWLINE)

Documentation

Send the input received to Eshell for parsing and processing.

After eshell-last-output-end, sends all text from that marker to point as input. Before that marker, calls eshell-get-old-input to retrieve old input, copies it to the end of the buffer, and sends it.

If USE-REGION is non-nil, the current region (between point and mark) will be used as input.

If QUEUE-P is non-nil, input will be queued until the next prompt, rather than sent to the currently active process. If no process, the input is processed immediately.

If NO-NEWLINE is non-nil, the input is sent without an implied final newline.
