|
help
|
|
One common problem reported on the mailing list is the "can't
|
|
access tty; job control turned off" error message, which typically
|
|
appears when one tries to use a shell with stdin/stdout on
|
|
/dev/console.
|
|
This device is special - it cannot be a controlling tty.
|
|
|
|
The proper solution is to use the correct device instead of
|
|
/dev/console.
|
|
|
|
cttyhack provides a "quick and dirty" solution to this problem.
|
|
It analyzes stdin with various ioctls, trying to determine whether
|
|
it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
|
|
On Linux it also checks sysfs for a pointer to the active console.
|
|
If cttyhack is able to find the real console device, it closes
|
|
stdin/out/err and reopens that device.
|
|
Then it executes the given program. Opening the device will make
|
|
that device a controlling tty. This may require cttyhack
|
|
to be a session leader.
|
|
|
|
Example for /etc/inittab (for busybox init):
|
|
|
|
::respawn:/bin/cttyhack /bin/sh
|
|
|
|
Starting an interactive shell from boot shell script:
|
|
|
|
setsid cttyhack sh
|
|
|
|
Giving controlling tty to shell running with PID 1:
|
|
|
|
# exec cttyhack sh
|
|
|
|
Without cttyhack, you need to know exact tty name,
|
|
and do something like this:
|
|
|
|
# exec setsid sh -c 'exec sh </dev/tty1 >/dev/tty1 2>&1'
|
|
|
|
Starting getty on a controlling tty from a shell script:
|
|
|
|
# getty 115200 $(cttyhack)

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.

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.
|
|
|
|
However, there are drawbacks: it is problematic in chroot jails
|
|
without mounted /proc, and ps/top may show command name as 'exe'
|
|
for applets started this way.

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.

Allow scripts to be compressed and embedded in the busybox
|
|
binary. The scripts should be placed in the 'embed' directory
|
|
at build time. Like applets, scripts can be run as
|
|
'busybox SCRIPT ...' or by linking their name to the binary.
|
|
|
|
This also allows applets to be implemented as scripts: place
|
|
the script in 'applets_sh' and a stub C file containing
|
|
configuration in the appropriate subsystem directory.
