Boolean which substitutes the variable expression with the local variable name.

For example: var_14h as rbp - var_14h, in the disassembly.

Change endianness. "true" means big-endian, "false" is for little-endian. "file.id" and "file.flag" both to be true.

If this variable is enabled, help messages will be displayed along with command names in tab completion for commands.

This variable specifies the mode for colorized screen output: "false" (or 0) means no colors, "true" (or 1) means 16-colors mode, 2 means 256-colors mode, 3 means 16 million-colors mode. If your favorite theme looks weird, try to bump this up.

This variable accepts a full-featured expression or a pointer/flag (eg. eip). If set, radare will set seek position to its value on startup.

If you have set up any flagzones (fz?), this variable will let you display the scrollbar with the flagzones, in Visual mode. Set it to 1 to display the scrollbar at the right end, 2 for the top and 3 to display it at the bottom.

A boolen variable to show UTF-8 characters instead of ANSI.

Enables or disables "fortune" messages displayed at each radare start.

Fortunes are classified by type. This variable determines which types are allowed for displaying when cfg.fortunes is true, so they can be fine-tuned on what's appropriate for the intended audience. Current types are tips, fun, nsfw, creepy.

This variable lets you set the size of stack in bytes.

RC files are r2 scripts that are loaded at startup time. Those files must be in 3 different places:

radare2 will first try to load /usr/share/radare2/radare2rc

Each user in the system can have its own r2 scripts to run on startup to select the color scheme, and other custom options by having r2 commands in there.
