1. Space saving

Recently, the server space is often insufficient, causing alarms. Therefore, after testing, I compress and store all the logs, such as the first 6.1 GB of xxx logs on a machine, and then 1.2 GB of logs are compressed by almost. in this way, I can save a lot of space, but I often need to analyze logs. In this case, I can use z-series commands to analyze log efficiency faster than that without compression, as shown in

Second, faster Efficiency

Use zcat to search logs after compression

[Root @ wds] # time zcat xxxx.tar.gz | wc-l
