Why do I lose log lines when gzipping?
However, if you look at what gzip does, you see that it doesn’t delete the file until after it’s one writing the output file. That means that there always is a race condition where log lines might be lost for lines logs being written gzipping.
How does piping and redirection work in Linux?

Piping and Redirection works by essentially controlling the flow of standard inputs and standard outputs. Piping is a technique that lets you use Linux commands as building blocks to build your own custom commands.
