To display the contents of a file in Linux, you can use the following commands:
- Using cat command: The cat command can be used to display the contents of a file in the terminal. Simply type cat followed by the file name and press Enter. For example: cat filename.txt
- Using more command: The more command allows you to view the contents of a file page by page. This is useful when dealing with long files. Enter more followed by the file name and press Enter. You can scroll through the file using the spacebar or arrow keys. Press q to exit. For example: more filename.txt
- Using less command: The less command is similar to the more command but provides more advanced features. It also allows backward scrolling and searching within the file. Enter less followed by the file name and press Enter. Scroll using the spacebar or arrow keys, and press q to exit. For example: less filename.txt
- Using head command: The head command displays the first few lines of a file. By default, it shows the first 10 lines. You can also specify the number of lines you want to display. Type head -n followed by the number of lines and the file name. For example, to display the first 5 lines: head -n 5 filename.txt
- Using tail command: The tail command displays the last few lines of a file. Similar to the head command, it shows the last 10 lines by default but can display a specific number of lines. Type tail -n followed by the number of lines and the file name. For example, to display the last 5 lines: tail -n 5 filename.txt
These commands provide different ways to display the contents of a file in Linux, allowing you to choose the one that suits your needs best.
