Enabling it will choose Kconfig defaults which favor reduced flash or memory requirements over extra features. config SHELL_STACK_SIZE int "Shell thread stack size" default 3168 if OPENTHREAD_SHELL && OPENTHREAD_JOINER default 2616 if OPENTHREAD_SHELL default 2048 if MULTITHREADING default 0 if !MULTITHREADING help Stack size for thread created for each instance. config SHELL_BACKSPACE_MODE_DELETE bool "Default escape code for backspace is DELETE (0x7F)" default y help Terminals have different escape code settings for backspace button. Some terminals send code: 0x08 (backspace) other 0x7F (delete). When this option is set shell will expect 0x7F for backspace key. config SHELL_CMD_BUFF_SIZE int "Shell command buffer size" default 128 if SHELL_MINIMAL default 256 help Maximum command size in bytes. One byte is reserved for the string terminator character. config SHELL_PRINTF_BUFF_SIZE int "Shell print buffer size" default 30 help Maximum text buffer size for fprintf function. It is working like stdio buffering in Linux systems to limit number of peripheral access calls. config SHELL_DEFAULT_TERMINAL_WIDTH int "Default terminal width" default 80 help Default terminal width is used to break lines. config SHELL_DEFAULT_TERMINAL_HEIGHT int "Default terminal height" default 24 config SHELL_ARGC_MAX int "Maximum arguments in shell command" range 3 255 default 12 help Maximum number of arguments that can build a command. config SHELL_TAB bool "Enable the Tab button support in shell" default y if !SHELL_MINIMAL help Enable using the Tab button in the shell. The button can be used for prompting commands, or for autocompletion. This feature has high impact on flash usage. config SHELL_TAB_AUTOCOMPLETION bool "Enable commands autocompletion with the Tab button" depends on SHELL_TAB default y if !SHELL_MINIMAL help Enable commands and subcommands autocompletion with the Tab key. This function can be deactivated to save some flash. config SHELL_WILDCARD bool "Enable wildcard support in shell" select FNMATCH default y if !SHELL_MINIMAL help Enables using wildcards: * and ? in the shell. config SHELL_ECHO_STATUS bool "Enable echo on shell" default y help If enabled shell prints back every input byte. config SHELL_START_OBSCURED bool "Display asterisk when echoing" default n help If enabled, don't echo actual character, but echo * instead. This is used for login prompts. config SHELL_VT100_COLORS bool "Enable colors in shell" default y if !SHELL_MINIMAL help If enabled VT100 colors are used in shell (e.g. print errors in red). config SHELL_GETOPT bool "Enable getopt support" select GETOPT help Enables getopt support in the shell. config SHELL_METAKEYS bool "Enable metakeys" default y if !SHELL_MINIMAL help Enables shell meta keys: Ctrl+a, Ctrl+b, Ctrl+c, Ctrl+d, Ctrl+e, Ctrl+f, Ctrl+k, Ctrl+l, Ctrl+u, Ctrl+w, Alt+b, Alt+f Meta keys will not be active when shell echo is set to off. config SHELL_HELP bool "Enable help message" default y if !SHELL_MINIMAL help Enables shell functions for printing formatted help message. config SHELL_HELP_OPT_PARSE bool "Parse -h and --help options" depends on SHELL_HELP depends on !SHELL_GETOPT default y help Shell parses command to find '-h' or '--help' string.

Each time terminal screen width is changed resize command must be called to ensure correct text display on the terminal screen. The resize command can be turned off to save code memory (~0,5k). config SHELL_CMDS_SELECT bool "Enable select command" depends on SHELL_CMDS help This option enables select command. It can be used to set new root command. Exit to main command tree is with alt+r. config SHELL_LOG_BACKEND bool "Enable shell log backend" depends on !LOG_MINIMAL default y if LOG help When enabled, backend will use the shell for logging. This option is enabled by default. Disabling this option disables log output to all shell backends. Disabling log output to a specific shell backend can be achieved using the shell backend's LOG_LEVEL option (e.g. CONFIG_SHELL_TELNET_INIT_LOG_LEVEL_NONE=y). source "subsys/shell/modules/Kconfig" endif # SHELL
