How do you use sed command with an example?

`. The description should be properly formatted. Here's how you can achieve that using `sed`: ```bash sed -E ' s|

.*

||g; # Remove

title s|(.*description\.)|

\1

|g; # Wrap the description s|(.*Keywords: .*

)|

|g; # Wrap the keywords s|

|

|; # Close content div after ' input.txt ``` ### Breakdown of the `sed` Commands 1. `s|

.*

||g;`: This removes the `

` title entirely from the document. 2. `s|(.*description\.)|

\1

)|

|g;`: Wraps the keywords section with a `div`. 4. `s|

|;`: Closes the `content` div after the last paragraph tag. ### Final Command You can save the result into a new file by redirecting: ```bash sed -E ... input.txt > output.html ``` ### Example Output The resulting HTML content after processing with `sed` would look like this: ```html ``` ### Full Example in a Markdown Code Block Here’s what the full `sed` command example looks like in a stylized code block: ```php # Sample sed command usage to format HTML sed -E ' s|
