How to use the “cat” command to view file contents in L…

In Linux, you can use the following command to view file content using the cat command:

cat 文件名

For example, to view the contents of a file named example.txt, you can execute the following command:

cat example.txt

The file’s contents will be displayed in the terminal window. Note that if the file is very large, the cat command may display all the content at once, causing the terminal window to be unable to accommodate it and for you to view all the content directly. If you only want to view a portion of the file, you can use the less command as shown below.

less 文件名

The content of the file will be displayed in a paginated manner, and you can use the arrow keys and page up/down keys to navigate the file. To exit the “less” command, press the q key.
