How do I permanently change the disassembly syntax in Radare2?

Question

As the title says, I am trying to change the default disassembly syntax in Radare2 from Intel to AT&T. Looking up documentation, I found the following.

[0x00405e1c]> e asm.syntax=att

However, changing syntax this way does not persist across sessions. Is there a command I can use to save settings permanently?

Answer 1

From Radare2 book:

The core reads ~/.config/radare2/radare2rc while starting. You can add e commands to this file to tune the radare2 configuration to your taste.
