| 232 | help |
| 233 | One common problem reported on the mailing list is the "can't |
| 234 | access tty; job control turned off" error message, which typically |
| 235 | appears when one tries to use a shell with stdin/stdout on |
| 236 | /dev/console. |
| 237 | This device is special - it cannot be a controlling tty. |
| 238 | |
| 239 | The proper solution is to use the correct device instead of |
| 240 | /dev/console. |
| 241 | |
| 242 | cttyhack provides a "quick and dirty" solution to this problem. |
| 243 | It analyzes stdin with various ioctls, trying to determine whether |
| 244 | it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line). |
| 245 | On Linux it also checks sysfs for a pointer to the active console. |
| 246 | If cttyhack is able to find the real console device, it closes |
| 247 | stdin/out/err and reopens that device. |
| 248 | Then it executes the given program. Opening the device will make |
| 249 | that device a controlling tty. This may require cttyhack |
| 250 | to be a session leader. |
| 251 | |
| 252 | Example for /etc/inittab (for busybox init): |
| 253 | |
| 254 | ::respawn:/bin/cttyhack /bin/sh |
| 255 | |
| 256 | Starting an interactive shell from boot shell script: |
| 257 | |
| 258 | setsid cttyhack sh |
| 259 | |
| 260 | Giving controlling tty to shell running with PID 1: |
| 261 | |
| 262 | # exec cttyhack sh |
| 263 | |
| 264 | Without cttyhack, you need to know exact tty name, |
| 265 | and do something like this: |
| 266 | |
| 267 | # exec setsid sh -c 'exec sh </dev/tty1 >/dev/tty1 2>&1' |

| 542 | This option causes busybox shells to use busybox applets |
| 543 | in preference to executables in the PATH whenever possible. For |
| 544 | example, entering the command 'ifconfig' into the shell would cause |
| 545 | busybox to use the ifconfig busybox applet. Specifying the fully |
| 546 | qualified executable name, such as '/sbin/ifconfig' will still |
| 547 | execute the /sbin/ifconfig executable on the filesystem. This option |
| 548 | is generally used when creating a statically linked version of busybox |
| 549 | for use as a rescue shell, in the event that you screw up your system. |
| 550 | |
| 551 | This is implemented by re-execing /proc/self/exe (typically) |
| 552 | with right parameters. |
| 553 | |
| 554 | However, there are drawbacks: it is problematic in chroot jails |
| 555 | without mounted /proc, and ps/top may show command name as 'exe' |
| 556 | for applets started this way. |

| 562 | help |
| 563 | This option causes busybox shells to not execute typical |
| 564 | fork/exec/wait sequence, but call <applet>_main directly, |
| 565 | if possible. (Sometimes it is not possible: for example, |
| 566 | this is not possible in pipes). |
| 567 | |
| 568 | This will be done only for some applets (those which are marked |
| 569 | NOFORK in include/applets.h). |
| 570 | |
| 571 | This may significantly speed up some shell scripts. |

| 597 | Allow scripts to be compressed and embedded in the busybox |
