如何停止写入BASH中的日志文件？

Question

I'm using this code to write all terminal's output to the file

exec > >(tee -a "${LOG_FILE}" )
exec 2> >(tee -a "${LOG_FILE}" >&2)

How to tell it to stop? If, for example, I don't want some output to get into log..

Thank you!

Answer 1

It's not completely clear what your goal is here, but here is something to try.

Do you know about the script utility? You can run script myTerminalOutputFile and any commands and output after that will be captured to myTerminalOutputFile . The downside is that it captures everything. You'll see funny screen control chars like ^[[5m;27j . So do a quick test to see if that works for you.

To finish capturing output just type exit and you are returned to you parent shell cmd-line.

Warning: check man script for details about the inherent funkyness of your particular OS's version of script. Some are better than others. script -k myTerminalOutputFile may work better in this case.

您可以通过“ sed”管道传输，然后通过tee进入日志文件
