rtl_sdr:tldr:8d829

The command "rtl_sdr" is a command-line tool used to interact with RTL-SDR (Software Defined Radio) dongles.

Here is the breakdown of the command and its options:

• "rtl_sdr": This is the name of the command.

• "-f ${100000000}": This option specifies the frequency to tune the RTL-SDR dongle to. In this case, the frequency is set to 100,000,000 Hz (100 MHz). You can replace this value with any frequency you want to tune to.

• "-s ${2400000}": This option sets the sample rate of the RTL-SDR dongle. In this case, it is set to 2,400,000 samples per second (2.4 Msps). You can adjust this value depending on your requirements and the capabilities of your RTL-SDR device.

• "-": This option tells the command to read data from the dongle and output it to the standard output (usually the terminal screen). The hyphen character ("-") serves as a placeholder for the output file name. If you want to save the data to a file instead, you can replace the hyphen with the desired file name.

This command essentially instructs the RTL-SDR dongle to tune to a specific frequency and capture data at a particular sample rate, and then outputs the data to the standard output for further processing or analysis.
