Hackrf one Help

[Matthias_2277]

Can someone tell me how to do this on linux in the console hackrf_transfer option [-a set_amp] # Set Amp 1=Enable, 0=Disable.
to switch on and off .
don't know how to enter it under linux mint.
can someone tell me the command:

hackrf_transfer

-r <filename> # Receive data into file.
-t <filename> # Transmit data from file.
-w # Receive data into file with WAV header and automatic name.
# This is for SDR# compatibility and may not work with other software.
[-f set_freq_hz] # Set Freq in Hz
[-a set_amp] # Set Amp 1=Enable, 0=Disable.
[-l gain_db] # Set lna gain, 0-40dB, 8dB steps
[-i gain_db] # Set vga(if) gain, 0-62dB, 2dB steps
[-x gain_db] # Set TX vga gain, 0-47dB, 1dB steps
[-s sample_rate_hz] # Set sample rate in Hz (8/10/12.5/16/20MHz)
[-n num_samples] # Number of samples to transfer (default is unlimited).
[-b baseband_filter_bw_hz] # Set baseband filter bandwidth in MHz.

Possible values:
1.75/2.5/3.5/5/5.5/6/7/8/9/10/12/14/15/20/24/28MHz,
default < sample_rate_hz.


I just want to know how to enter it correctly to turn it on and off


Thanks
