The command symbols of Linux and Unix systems are similar to a large extent, because Linux is developed from Unix and retains many Unix-related concepts and commands.

Many basic commands (such as ls, cd, mkdir, rm, cp, mv, cat, grep, etc.) are the same in Linux and Unix, and are used in similar ways. These commands are typically used for common tasks such as file and directory manipulation, text processing, searching, and filtering.

However, due to differences in the implementation and development history of different Unix systems, some specific commands and options may vary. For example, some features and options may differ slightly across different Unix distributions, or have additional commands specific to a particular system.

In addition, Linux also introduces some unique commands and tools of its own, as well as some commands specific to Linux system management and configuration (such as systemctl, apt-get, yum, etc.).

In general, although the command symbols of Linux and Unix are to a large extent the same or similar, there may be differences in some details. Therefore, when using it in a specific environment, you need to pay attention to the differences in commands and options, and consult relevant documentation and reference materials.
