Advanced techniques for using the more command in Linux

Advanced usage of the more command under Linux

Abstract: This article will introduce the advanced usage of the more command in the Linux operating system, including using the more command to perform text search, jump to a specified number of lines, display by page, and exit. more command and other operations, and provide specific code examples.

1. Use the more command for text search

When using the more command, sometimes we need to search for specific text content. To perform a text search within the more command, use a slash (/) followed by the search keyword.

For example, to search for the keyword "hello" in a file, you can use the following command:

more myfile.txt
/hello

After executing the above command, the more command will position the cursor to the first match Go to the "hello" keyword and highlight it.

2. Jump to the specified number of lines

When we need to quickly jump to the specified number of lines in a file, we can use the "number of lines" option of the more command.

For example, to jump to the 10th line of a file, you can use the following command:

more +10 myfile.txt

After executing the above command, the more command will jump directly to the 10th line of the file, and Display the file contents starting from this line.

3. Display by page

When processing a long file, in order to facilitate browsing of the file content, we can use the more command to display the file content by page.

For example, to display the contents of a file page by page, you can use the following command:

more -d myfile.txt

After executing the above command, the more command will display the contents of the file one page at a time, and Display the words "--More--" at the bottom of the screen and wait for the user to press the space bar to turn pages.

4. Exit the more command

If we suddenly need to exit the more command while browsing files, we can press the "q" key to exit directly.

For example, when we use the more command to display the contents of a file, if we want to exit the more command, we only need to press the "q" key.

To sum up, this article introduces the advanced usage of the more command in the Linux operating system and provides corresponding code examples, including using the more command to perform text search, jump to a specified number of lines, and display by page , exit the more command and other operations. By learning and using the advanced usage of the more command, we can better manage and browse text files and improve work efficiency.

Reference code example:

Example 1: Use the more command for text search

more myfile.txt
/hello

Example 2: Jump to the specified line number

more +10 myfile.txt

Example 3 : Display by page

more -d myfile.txt

Example 4: Exit more command

more myfile.txt
q
