Two days ago, the "some little-known but interesting Unix/Linux commands" series were released.Article, Received praise from some friends. (I wanted to write "a lot of friends", but I thought Linux was really a small crowd, so brother D would not be forced! Haha) D. Will make persistent efforts. The links to the first two articles are as follows:
- Some little-known but interesting Unix/Linux commands (1)
- Some little-known but interesting Unix/Linux commands (2)
In the third article in this series, Dr. D will continue to introduce some interesting Unix/Linux commands.
Interesting commands
-
- MTR,A very useful tool for determining network connectivity;
-
- Cssh,Cluster SSH is a tool that can operate on multiple windows simultaneously;
-
- Wireshark,A powerful network packet capture tool that provides users with various information about networks and upper-layer protocols. It is the most popular network analysis tool in the world;
-
- Tshark,The command line tool corresponding to Wireshark;
-
- Host,The DNS resolution query tool resolves a host name to an IP address or an IP address to a host name;
-
- Dig,The DNS resolution query tool is more explicit than the host command, but not easy to understand;
-
- Lsof,Is short for list open files. It is a tool used to list open files in the current system;
-
- Dstat,Collect the running data of the system and collect the specified performance resources;
- Iostat,A query tool for CPU and hard disk I/O usage status;
-
- Htop,TOP Command upgrade, interactive command line process monitor;
-
- Last,Query System Login logs;
-
- W,Displays the user information currently logged on to the system, which is more powerful than who;
-
- ID,Query user IDs and group IDs;
-
- SAR,It is mainly responsible for collecting, reporting and storing system operation information;
-
- Iftop,Similar to top real-time traffic monitoring tools;
-
- SS,Command Used to view socket information, an upgraded version of netstat;
-
- Dmesg,A tool used to display the control information of the kernel buffer system;
-
- Hdparm,Used to detect, display, and set parameters of the IDE or SCSI hard disk;
-
- Lsb_release,Used to view the release information of the current system;
-
- Lshw,That is, list hardware, a tool for viewing hardware information;
And
The original plan was to write three articles for introduction. Today, I looked at the original post and found many interesting things. Therefore, you may need to write a few more articles to complete the introduction. In addition, Brother D is not particularly familiar with Linux, and the translation and sorting process is also a learning process; he wants to get something better. Therefore, every article is controlled at 20 instructions. If you have good suggestions or comments, please leave a message to discuss them. D. Thank you!
