I like running shell programs using Emacs ansi-term mode, but I wonder how to set the maximum buffer size in ansi-term mode so I won't lose command history even when there are lot of lines? (Google doesn't seem to give a obvious answer.)

  • Are you worried about the size of the scroll buffer or the command history? – DrC Mar 18 '13 at 02:40
  • @DrC Yes, I am running a program that generates a lot of output and the default buffer size would not fit. – chtlp Mar 18 '13 at 02:51

The variable term-buffer-maximum-size controls this value. Setting it to 0 should buffer everything (haven't used it but that is what the doc says). I'd be tempted to use a large value instead so a runaway program doesn't cause serious issues. It defaults to 2048 lines. 

(setq term-buffer-maximum-size 0)

in your term-mode-hook function should do it.
