I tried adding hook to term-mode-hook to call comint-send-string:

  (add-hook
   'term-mode-hook
   (lambda ()
     (comint-send-string (get-buffer-process (current-buffer)) "alias t='echo test'")
  ))

But I got (error "Buffer *ansi-term* has no process").

term-exec-hook is a variable defined in term.el.

Called each time a process is exec'd by term-exec. This is called after the process is cranked up. It is useful for things that must be done each time a process is executed in a term mode buffer (e.g., set-process-query-on-exit-flag). In contrast, term-mode-hook is only executed once, when the buffer is created.

I would also use the term API for sending input to the process, rather than using comint-send-string.

term-send-string is a compiled Lisp function in term.el.

(term-send-string PROC STR)

Send to PROC the contents of STR as input. This is equivalent to process-send-string, except that long input strings are broken up into chunks of size term-input-chunk-size. Processes are given a chance to output between chunks. This can help prevent processes from hanging when you send them long inputs on some OS's.

  • Thanks! Following codes work for me: ` (add-hook 'term-exec-hook (lambda () (term-send-string (get-buffer-process (current-buffer)) "alias t='echo test'\n") )) `
