我想捕获 Python shell 输出以及发送给它的输入。例如,在以下用例中,help() 也应出现在 capture.log 的第 4 行中:
$ echo "help()" | python3 -i > capture.log 2>&1
$ cat capture.log
Python 3.4.2 (default, Oct 8 2014, 10:45:20)

Type "help", "copyright", "credits" or "license" for more information.

最佳答案
假设一个类 Unix 环境,您可以使用 script
命令捕获所有 tty
输入和输出:
$ script capture.log
Script started, output file is capture.log
$ python3
# python interactive session here
$ exit
Script done, output file is capture.log
$ cat capture.log
Script started on Thu Aug 18 21:21:55 2016
$ python3

如果像问题示例中那样,Python 完全由 stdin
管道驱动并且目标是捕获管道输入和 Python 输出,您可以使用 tee
命令:
$ echo "help()" | tee capture.log | python3 -i >> capture.log 2>&1
$ cat capture.log
help()

如您所见,输入和输出都被捕获,但它们没有对齐。
