问题描述
在OSX使用bash。我该如何设置我的外壳，使其覆盖某个文件，我最近命令的输出？这将是用于查看/搜索/分析，我没有先见之明，管到一个文件大输出真的很方便。感谢您的帮助！
Using bash on OSX. How can I set up my shell so that it overwrites a certain file with the output of my most recent command? This would be really convenient for viewing/searching/analyzing large outputs that I didn't have the foresight to pipe to a file. Thanks for the help!
推荐答案
使用剧本键，你的命令和它们的输出从存储在日志文件中，直到您退出剧本。
Use script and your commands and their output are stored in a log file until you exit from script.
script mylogfile.output
运行此命令后，就回到了bash命令提示符，你可以继续你的bash会话正常。所有命令和输出中被保存到mylogfile.output。
After running this command, you are back at the bash command prompt and you can continue your bash session as normal. All commands and ouput are saved to "mylogfile.output".
所以它会自动启动你可以把它放在你的〜/ .bashrc文件如下：
You could put this in your ~/.bashrc file so it starts automatically as follows:
[ -n "$PS1" -a -z "$SCRIPT_STARTED" ] || export SCRIPT_STARTED=$$
[ "$SCRIPT_STARTED" -eq $$ ] && script -q ~/mylogfile.output
在-q选项，可以悄悄地开始这是〜/ .bashrc中命令安全。
