In daily testing work, Linux is often used when it comes to setting up a test environment and locating related problems by viewing logs. In interviews with test engineers, there are often written test or interview questions to test the tester's familiarity with Linux. To a certain extent, here are the Linux commands that test engineers need to know.
Linux, as a commonly used operating system, is an essential skill for test engineers. Proficiency in Linux commands can improve the work efficiency of test engineers. Let's introduce some commonly used Linux commands.
File and directory management commands
These commands are used to manage files and directories in Linux systems, including viewing files and directories, creating and deleting files and directories, etc.
ls: used to view files and directories in the current directory.
cat: used to view the contents of a file, and can also be used to merge multiple files.
rm: Used to delete files and directories. The -r option can be used to delete directories recursively.
touch: Timestamp for creating a new file or modifying an existing file.
mkdir: used to create new directories.
chmod: used to modify the permissions of files and directories.
cp: used to copy files and directories.
mv: used to move files and directories.
System management commands
These commands are used to manage Linux systems, including viewing system information, installing and uninstalling software packages, viewing processes, etc.
top: Used to view the system's processes and resource usage in real time.
df: Checks disk space, showing usage of each file system.
ps: Used to list the current process and process details.
yum: used to manage software packages and components, install and uninstall software.
service: Services and daemons used to manage the system.
netstat: Used to display network connections, routing tables, and network interface information.
network commands
These commands are used to manage network connections and network settings.
ping: used to test the connection status of the host.
nslookup: Used to look up the IP address of a domain name.
ifconfig: Display and configure network interface information.
route: used to display and configure network routing tables.
Summarize
Here we just introduce some commonly used Linux commands. Proficient in these commands can allow test engineers to handle daily work more efficiently, and can also increase the basic skills and knowledge reserves of test engineers. Of course, there are many other commands and techniques in actual use, which require continuous learning and practice. In addition, many testers who are new to the industry have left private messages in the background, especially outsourced employees. They will say that when entering the company, the technical interview only requires writing test cases and doing a qualified job, but many times the superior team leader will assign some other Tasks, such as deploying a test environment or building a test platform, will always be daunting because you do not have complete experience in setting up during self-study. Here is a unified reply. When we encounter a big problem, we can split it into smaller problems and solve them one by one.
Finally, I would like to thank everyone who reads my article carefully. Reciprocity is always necessary. Although it is not a very valuable thing, if you can use it, you can take it directly:
This information should be the most comprehensive and complete preparation warehouse for [software testing] friends. This warehouse has also accompanied tens of thousands of test engineers through the most difficult journey. I hope it can also help you!
