Bash HTTP Requests Without Curl

WireByte Staff · June 16, 2026

A developer has discovered a method to make HTTP requests using Bash without relying on external tools like curl. This technique involves using the /dev/tcp device file to establish a connection and send requests. The approach has been confirmed to work within Docker environments.

Key points

  • The method uses the /dev/tcp device file to establish a connection to a host and port, allowing for HTTP requests to be sent via Bash.
  • This technique has been confirmed to work within Docker environments, where external tools like curl may not be available.
  • The approach involves using the `exec` command to open a connection and the `printf` command to send the request.
  • The method can be used to add headers to the request by including additional lines in the `printf` command.
