How do you write the command to set the lowest fee during a transfer with the monero cli?
You have to understand priority levels using the transfer command. Read: What does the "default" priority (priority = 0) do in monero-wallet-cli?
There are 4 levels:
First note that the priority levels unimportant, normal, elevated, and priority correspond to multipliers of x1, x4, x20, and x166, respectively.
To send with lowest you would do:
transfer unimportant <address> <amount>
[wallet 46xxxx]: transfer unimportant 4BSX2Par....LU2T6xxx 2 There is currently a 1 block backlog at that fee level. Is this okay? (Y/Yes/N/No)Y Sending 2.000000000000.
