Given ...
#### (comint-run "/bin/bash")
... the following ...
#### (with-current-buffer "*bash*"
#### (insert "if true
#### then
#### echo hello
#### fi")
#### (comint-send-input))
... outputs ...
#### $ if true
#### then
#### echo hello
#### fi
#### > > > hello
Not good.
Similarly, ...
#### (with-current-buffer "*bash*"
#### (dolist (line (list "if true"
#### "then"
#### "echo hello"
#### "fi"))
#### (insert line)
#### (comint-send-input)))
... also gives the same output.
(I took this as a minimal working bug reproducer).
After investigating, I found that ...
#### (with-current-buffer "*bash*"
#### (let ((comint-process-echoes t))
#### (dolist (line (list "if true"
#### "then"
#### "echo hello"
#### "fi"))
#### (insert line)
#### (comint-send-input))))
... outputs (perhaps the desired) ...
$ if true
> then
> echo hello
> fi
hello
Would this help?
