Curl Set User Agent Command on Linux or Unix

To set the user agent when using curl on a Linux or Unix system, you can use the -A or --user-agent option. This option allows you to specify a string that will be sent as the User-Agent header in the HTTP request.

For example:

curl -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3" https://example.com/

This will send a request to https://example.com/ with the specified user agent string. The server will see the request as coming from a Chrome browser running on Windows 10.

You can also use the --user-agent option to specify a file containing the user agent string. The file should contain the user agent string on a single line.

For example:

curl --user-agent user-agent.txt https://example.com/

This will send a request to https://example.com/ with the user agent string specified in the user-agent.txt file.

Note that some servers may block or modify requests based on the user agent, so it is important to use a realistic and appropriate user agent when testing or accessing web pages.
