Collect a little information about Linux

When I first arrived, it was also the first time I wrote a technology-related blog. I 'd like to share a few articles about Linux in my favorites. I hope I can help anyone who needs it.

1. Advanced Bash Script Programming Guide: This website provides a detailed description of all aspects of Bash Shell programming, which can be used as learning materials or reference books. The English version is Advanced Bash-Scripting Guide.

2. Iptables guide 1.1.19: Unfortunately, this booklet has never been read, but it is also a good reference.

3. Awk learning notes: Awk, haha, it's a text analysis tool on Linux. You know it...
