实时修改`tail -f`输出

Question

The logs for my work are output with a | instead of a newline, making them incredibly difficult to read. What I do now is copy and paste them into vim and run :%s/|/\\r/g to replace all pipe's with a new line.

I'd love to be able to do this in real time in the tail -f output of the logs. So instead of having to copy and paste it (or run sed on the log file), I could just read the logs right away as they are written to the file, with the pipe separator replaced with new lines.

Is there a way to do this? (I can't modify the line separator for the log output)

Answer 1

您可以将tail -f输出管道传输到sed并运行与vim一起运行的相同正则表达式（转义已添加）：

tail -f file | sed -e s/\|/\\n/g -

Answer 2

I think

tail -f <log file> | tr \| \n | less 

or some such might work. Might take some fiddling.
