Using a Mac terminal is not difficult, you can get started by mastering a few common commands and basic ideas. File and directory operations are the basics, including ls viewing files, cd accessing directories, mkdir creating folders, CP copying files, rm deletion files (removing directories requires adding -r); viewing and editing files can be displayed by cat, open using the default program, and simply editing nano; when obtaining the path, you can directly drag and drop the Finder file to the terminal to automatically complete; use the man command to view the help instructions, press the Tab key to automatically complete the command or path to improve efficiency; after practicing more, you will find that the terminal is faster and more flexible than the graphical interface.

Using Terminal for Mac is actually not that difficult. The key is to master several common commands and basic ideas. Many people think that the interface with black and white characters is scary at first, but in fact, as long as you are familiar with a few basic operations, you will find that it is faster and more flexible than the graphical interface.

File and directory operations are the basis

The most common use of Terminal is to manipulate files and folders. For example, checking files in the current directory, creating new folders, copying and moving files can all be completed through commands.

• ls : List all files and folders in the current directory
• cd 目錄名: enter the specified directory (for example, cd Desktop will enter the desktop)
• mkdir 文件夾名: Create a new folder
• cp 源路徑目標(biāo)路徑: copy file or directory
• rm 文件名: delete the file. If you want to delete the directory, you need to add the -r parameter

A small suggestion is that before executing the delete or move command, it is best to use ls to confirm the contents of the current directory to avoid mistaken deletion.

Tips for viewing and editing file content

Sometimes you need to quickly look at the contents of a certain file or make some minor changes, and you don’t need to open a complex editor.

• cat 文件名: directly display file content
• open 文件名: use the default program to open the file (for example, text files will be opened with TextEdit)
• nano 文件名: edit files with a simple editor built in terminal

For example, if you want to see what configuration is written in .bash_profile , you can directly enter cat .bash_profile . If you are not used to using Vim, nano is a good alternative. Just follow the prompts when saving.

Tips for fast path positioning

Many times you may not know the specific path of a file, or it may be troublesome to drag and drop the path. In fact, there is a small trick that can help you quickly get the path.

You can drag the file or folder in Finder directly into the Terminal window, and it will automatically complete the full path. This method is particularly practical when writing scripts or executing commands, and can save the hassle of manually entering paths.

Learn to use man and tab to improve efficiency

• Encountering an order you don't know? Try man 命令名, it will display the detailed description of this command
• When entering a command or path, press the Tab key to automatically complete it to reduce spelling errors

For example, if you type man ls , you can see various uses of ls . And when you enter cd Docu and press Tab , the system may automatically complete cd Documents , provided that the name uniquely matches.

Basically that's it. It may be a bit slow when you first use Terminal, but try it a few more times and you will find it really convenient.
