I wanted to store the captures directly to the csv file, for that I used the following command line

tshark -T fields -E separator="," -E header=y -E quote=d -e frame.number -e frame.time -e eth.src -e eth.dst -e ip.src -e ip.dst -e ip.proto subtype probereq

but I am getting the following error:

  Capturing on 'Ethernet'
tshark: Invalid capture filter "subtype probereq" for interface 'Ethernet'.

I also tried adding the name of the file to write in but it didn't help

What network interface are you capturing on? What version, of what operating system, is the machine on which you're capturing running?

As the error message states, that is not a valid capture (or display or read) filter.

What is the filter you are using in the gui?

Try to add exactly the same filter, prefixed with either -Y or -R, and you might need quotes.
