+ help
+ Choose which shell you want to be executed by 'bash' alias.
+ The ash shell is the most bash compatible and full featured one.
+
+ Note that selecting this option does not switch on any bash
+ compatibility code. It merely makes it possible to install
+ /bin/bash (sym)link and run scripts which start with
+ #!/bin/bash line.
+
+ Many systems use it in scripts which use bash-specific features,
+ even simple ones like $RANDOM. Without this option, busybox
+ can't be used for running them because it won't recongnize
+ "bash" as a supported applet name.

+ Enable 64-bit math support in the shell. This will make the shell
+ slightly larger, but will allow computation with very large numbers.
+ This is not in POSIX, so do not rely on this in portable code.

+ bool "Standalone shell"
+ default n
+ depends on (HUSH || ASH) && FEATURE_PREFER_APPLETS
+ help
+ This option causes busybox shells to use busybox applets
+ in preference to executables in the PATH whenever possible. For
+ example, entering the command 'ifconfig' into the shell would cause
+ busybox to use the ifconfig busybox applet. Specifying the fully
+ qualified executable name, such as '/sbin/ifconfig' will still
+ execute the /sbin/ifconfig executable on the filesystem. This option
+ is generally used when creating a statically linked version of busybox
+ for use as a rescue shell, in the event that you screw up your system.
+
+ This is implemented by re-execing /proc/self/exe (typically)
+ with right parameters. Some selected applets ("NOFORK" applets)
+ can even be executed without creating new process.
+ Instead, busybox will call <applet>_main() internally.
+
+ However, this causes problems in chroot jails without mounted /proc
+ and with ps/top (command name can be shown as 'exe' for applets
+ started this way).
+# untrue?
+# Note that this will *also* cause applets to take precedence
+# over shell builtins of the same name. So turning this on will
+# eliminate any performance gained by turning on the builtin "echo"
+# and "test" commands in ash.
+# untrue?
+# Note that when using this option, the shell will attempt to directly
+# run '/bin/busybox'. If you do not have the busybox binary sitting in
+# that exact location with that exact name, this option will not work at
+# all.
+
+config FEATURE_SH_NOFORK
+ bool "Run 'nofork' applets directly"
+ default n
+ depends on (HUSH || ASH) && FEATURE_PREFER_APPLETS
+ help
+ This option causes busybox shells to not execute typical
+ fork/exec/wait sequence, but call <applet>_main directly,
+ if possible. (Sometimes it is not possible: for example,
+ this is not possible in pipes).
+
+ This will be done only for some applets (those which are marked
+ NOFORK in include/applets.h).
+
+ This may significantly speed up some shell scripts.
+
+ This feature is relatively new. Use with care. Report bugs
+ to project mailing list.
+
+config FEATURE_SH_HISTFILESIZE
+ bool "Use $HISTFILESIZE"
+ default y
+ depends on HUSH || ASH
+ help
+ This option makes busybox shells to use $HISTFILESIZE variable
+ to set shell history size. Note that its max value is capped
+ by "History size" setting in library tuning section.
