How to save the numbered output?

To save the numbered output of a file using the cat -n command, you can use output redirection with the > symbol. Here’s how to do it:

Command:

cat -n /tmp/hello > numbered_hello.txt

Explanation:

• cat -n /tmp/hello: This command displays the contents of /tmp/hello with line numbers.
• >: This symbol redirects the output to a file.
• numbered_hello.txt: This is the name of the new file where the numbered output will be saved.

Result:

After running the command, you will have a file named numbered_hello.txt containing the numbered lines from /tmp/hello.
