So turning this on will 235 eliminate any performance gained by turning on the builtin "echo" 236 and "test" commands in ash. 237 238 Note that when using this option, the shell will attempt to directly 239 run '/bin/busybox'. If you do not have the busybox binary sitting in 240 that exact location with that exact name, this option will not work at 241 all. 242 243 config CONFIG_FEATURE_COMMAND_EDITING 244 bool "Command line editing" 245 default n 246 depends on CONFIG_MSH || CONFIG_LASH || CONFIG_HUSH || CONFIG_ASH 247 help 248 Enable command editing in shell. 249 250 config CONFIG_FEATURE_COMMAND_EDITING_VI 251 bool "vi-style line editing commands" 252 default n 253 depends on CONFIG_FEATURE_COMMAND_EDITING 254 help 255 Enable vi-style line editing in the shell.

Some selected applets ("NOFORK" applets) 283 can even be executed without creating new process. 284 Instead, busybox will call <applet>_main() internally. 285 286 However, this causes problems in chroot jails without mounted /proc 287 and with ps/top (command name can be shown as 'exe' for applets 288 started this way). 289 # untrue? 290 # Note that this will *also* cause applets to take precedence 291 # over shell builtins of the same name.

If you do not have the busybox binary sitting in 297 # that exact location with that exact name, this option will not work at 298 # all. 299 300 config CTTYHACK 301 bool "cttyhack" 302 default n 303 help 304 One common problem reported on the mailing list is "can't access tty; 305 job control turned off" error message which typically appears when 306 one tries to use shell with stdin/stdout opened to /dev/console. 307 This device is special - it cannot be a controlling tty. 308 309 Proper solution is to use correct device instead of /dev/console. 310 311 cttyhack provides "quick and dirty" solution to this problem. 312 It analyzes stdin with various ioctls, trying to determine whether 313 it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line). 314 If it detects one, it closes stdin/out/err and reopens that device. 315 Then it executes given program. Usage example for /etc/inittab 316 (for busybox init): 317 318 ::respawn:/bin/cttyhack /bin/sh 293 319 294 320 endmenu
