(b) Perform the following tasks in Linux (i) Display the last 20 lines of a text file (you need to create a text file) Answer: Create a Text File Using the Cat Command Our first method for creating text files uses the cat command. It’s useful if you want to immediately add some text to your new file. Just type the following command at the terminal prompt (replacing “sample.txt” with whatever you want to name your file), and then press Enter:

cat > sample.txt

After pressing Enter, you are not returned to the terminal prompt. Instead, the cursor is placed on the next line, and you can start entering text directly into your file. Type your lines of text, pressing Enter after each line. When you are done, press Ctrl+D to exit the file and return to the prompt.

To verify your file was created, you can use the ls command to show a directory listing for the file:

ls -l sample.txt

You can also use the cat command to view the contents of your file. Just type the following command at the prompt, and then press Enter:

cat sample.txt

To display last 20 lines of a file linux use the tail command.

$ tail -20 bigfile.txt

Displays the last 20 lines. The default is 10 if you leave out the -n option.

Other useful options: $ tail -c 100 bigfile.txt

Displays the last 100 bytes of the file ( without reguard for the lines). This can be used on binary

files if you know what you are doing.

The head command is the same as tail except that it operates on the begining of the file.

To get lines out of the middle of the file you can use them together: cat bigfile.txt |head -10|tail -2
