Reading a Rails log with vim, we can see a colored log. But when we use tail -f or less to watch the log, it isn't colorized anymore. Is there any way to see the colored log with tail or less or whatever?
使用vim读取Rails日志，我们可以看到彩色日志。但是当我们使用tail -f或更少来查看日志时，它不再着色了。有没有办法看到有尾巴或更少的彩色日志或其他什么？

pass -R to less for it to let colour escape sequences pass through, i.e.
将-R传递给less以使颜色转义序列通过，即
less -R log/development.log
This should result in them being displayed in colour, assuming you are using the proper terminal type
假设您使用正确的终端类型，这应该导致它们以彩色显示

tail -f log/development.log | ccze -A
You may need to install ccze
您可能需要安装ccze
sudo apt-get install ccze
it works better, not ideal but works
它效果更好，不理想但有效

You can't do that out of the box, since tail and less know nothing about Rails, and logs are saved a simple text files. You could use regular expressions to colorize output but I doubt it's worth the trouble.
你不能开箱即用，因为尾巴和Rails一无所知，日志保存了一个简单的文本文件。您可以使用正则表达式着色输出，但我怀疑这是值得的麻烦。
