How to set a custom user agent with cURL?

To set a custom user agent with cURL, you can use the -H or --header option followed by the User-Agent header value.

Here is an example command:

curl -H "User-Agent: Your_Custom_User_Agent" https://example.com/

Replace Your_Custom_User_Agent with the desired user agent string.

Additionally, you can create a user agent file, for example useragent.txt, that contains the desired user agent string. Then, you can use the --user-agent or -A option to specify the file as the source of the user agent:

curl -A "$(cat useragent.txt)" https://example.com/

This approach allows you to easily switch between different user agents by modifying the contents of the useragent.txt file.
