Busybox команды для линукс
BusyBox has been written with size-optimization and limited resources in mind. It is also extremely modular so you can easily include or exclude commands (or features) at compile time. This makes it easy to customize your embedded systems. To create a working system, just add a kernel, a shell (such as ash), and an editor (such as elvis-tiny or ae).
USAGE
For example, entering
will cause BusyBox to behave as ‘ls’ (if the ‘ls’ command has been compiled into BusyBox).
You can also invoke BusyBox by issuing the command as an argument on the command line. For example, entering
will also cause BusyBox to behave as ‘ls’.

Prints selected fields from each input FILE to standard output.
Displays the current time in the given FORMAT , or sets the system date.
This is a Tiny RPN calculator that understands the following operations: +, -, /, *, and, or, not, eor. i.e., ‘dc 2 2 add’ -> 4, and ‘dc 8 8 \* 2 2 + /’ -> 16
Copy a file, converting and formatting according to options
Numbers may be suffixed by c (x1), w (x2), b (x512), kD (x1000), k (x1024), MD (x1000000), M (x1048576), GD (x1000000000) or G (x1073741824).
Deallocate unused virtual terminal /dev/ttyN
Print the filesystem space used and space available.
Strips non-directory suffix from FILENAME
Prints or controls the kernel ring buffer
Converts FILE from dos format to unix format. When no option is given, the input is converted to the opposite output format. When no file is given, uses stdin for input and stdout for output.
Perform actions on debian packages (.debs)
Summarizes disk space used for each FILE and/or directory. Disk space is printed in units of 1024 bytes.
Prints out a binary keyboard translation table to standard output.

Prints the specified ARGs to stdout
Prints the current environment or runs a program after setting up the specified environment.
Prints the value of EXPRESSION to standard output.
EXPRESSION may be:
Beware that many operators need to be escaped or quoted for shells. Comparisons are arithmetic if both ARGs are numbers, else lexicographical. Pattern matches return the string matched between \( and \) or null; if \( and \) are not used, they return the number of characters matched or 0.
Return an exit code of FALSE (1).
Show and modify frame buffer settings
Forces floppy disk drive to detect disk change
Search for files in a directory hierarchy. The default PATH is the current directory; default EXPRESSION is ‘ -print ‘
EXPRESSION may consist of:

Performs a consistency check for MINIX filesystems.
Parse command options
Search for PATTERN in each FILE or standard input.
Uncompress FILE (or standard input if FILE is ‘-‘).
Compress FILE with maximum compression. When FILE is ‘-‘, reads standard input. Implies -c .

Print first 10 lines of each FILE to standard output. With more than one FILE , precede each with a header giving the file name. With no FILE , or when FILE is -, read standard input.
Print out a unique 32-bit identifier for the machine.
Get or set the hostname or DNS domain name. If a hostname is given (or FILE with the -F parameter), the host name will be set.
Print information for USERNAME or the current user
configure a network interface
Init is the parent of all processes.
This version of init is designed to be run only by the kernel.
BusyBox init doesn’t support multiple runlevels. The runlevels field of the /etc/inittab file is completely ignored by BusyBox init. If you want runlevels, use sysvinit.
BusyBox init works just fine without an inittab. If no inittab is found, it has the following default behavior:
if it detects that /dev/console is _not_ a serial console, it will also run:
If you choose to use an /etc/inittab file, the inittab entry format is as follows:
Example /etc/inittab file:
Loads the specified kernel modules into the kernel.
Send a signal (default is SIGTERM ) to the specified process(es).
——————————-
killall killall [ -signal ] process-name [process-name . ]
Send a signal (default is SIGTERM ) to the specified process(es).
Kernel logger. Options:
lash: The BusyBox LAme SHell (command interpreter)
This command does not yet have proper documentation.
Use lash just as you would use any other shell. It properly handles pipes, redirects, job control, can be used as the shell for scripts, and has a sufficient set of builtins to do what is needed. It does not (yet) support Bourne Shell syntax. If you need things like «if-then-else», «while», and such use ash or bash. If you just need a very simple and extremely small shell, this will do the job.
Prints out the length of the specified STRING .

LIBC NSS
If you are using a system that is using a remote LDAP server for authentication via GNU libc NSS , and you want to use BusyBox, then you will need to adjust the BusyBox source. Chances are though, that if you have enough space to install of that stuff on your system, then you probably want the full GNU utilities.
