 218         help
 219         One common problem reported on the mailing list is the "can't
 220         access tty; job control turned off" error message, which typically
 221         appears when one tries to use a shell with stdin/stdout on
 222         /dev/console.
 223         This device is special - it cannot be a controlling tty.
 224
 225         The proper solution is to use the correct device instead of
 226         /dev/console.
 227
 228         cttyhack provides a "quick and dirty" solution to this problem.
 229         It analyzes stdin with various ioctls, trying to determine whether
 230         it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
 231         On Linux it also checks sysfs for a pointer to the active console.
 232         If cttyhack is able to find the real console device, it closes
 233         stdin/out/err and reopens that device.
 234         Then it executes the given program. Opening the device will make
 235         that device a controlling tty. This may require cttyhack
 236         to be a session leader.
 237
 238         Example for /etc/inittab (for busybox init):
 239
 240         ::respawn:/bin/cttyhack /bin/sh
 241
 242         Starting an interactive shell from boot shell script:
 243
 244         setsid cttyhack sh
 245
 246         Giving controlling tty to shell running with PID 1:
 247
 248         # exec cttyhack sh
 249
 250         Without cttyhack, you need to know exact tty name,
 251         and do something like this:
 252
 253         # exec setsid sh -c 'exec sh </dev/tty1 >/dev/tty1 2>&1'
 254

 512         This option causes busybox shells to use busybox applets
 513         in preference to executables in the PATH whenever possible. For
 514         example, entering the command 'ifconfig' into the shell would cause
 515         busybox to use the ifconfig busybox applet. Specifying the fully
 516         qualified executable name, such as '/sbin/ifconfig' will still
 517         execute the /sbin/ifconfig executable on the filesystem. This option
 518         is generally used when creating a statically linked version of busybox
 519         for use as a rescue shell, in the event that you screw up your system.
 520
 521         This is implemented by re-execing /proc/self/exe (typically)
 522         with right parameters.
 523
 524         However, there are drawbacks: it is problematic in chroot jails
 525         without mounted /proc, and ps/top may show command name as 'exe'
 526         for applets started this way.

 533         This option causes busybox shells to not execute typical

 535         if possible. (Sometimes it is not possible: for example,
 536         this is not possible in pipes).
 537
 538         This will be done only for some applets (those which are marked
 539         NOFORK in include/applets.h).
