Define local variables.
Create a local variable called NAME, and give it VALUE. OPTION can
be any option accepted by `declare'.
Local variables can only be used within a function; they are visible
only to the function where they are defined and its children.

Returns success unless an invalid option is supplied, a variable
assignment error occurs, or the shell is not executing a function. |

Определение локальных переменных.
Создаёт локальную переменную с указанным именем и присваивает ей указанное значение. Параметром может быть
любой параметр, принимаемый командой «declare».
Локальные переменные можно использовать только внутри функции. Они видны
только той функции, в которой они определены, и её дочерним функциям.
Состояние выхода:
Возвращает успех, если был указан допустимый параметр, не возникла
ошибка присвоения переменной или командный процессор не выполняет функцию. |

Enable and disable shell builtins.
Enables and disables builtin shell commands. Disabling allows you to
execute a disk command which has the same name as a shell builtin
without using a full pathname.
Options:
-a [tab]print a list of builtins showing whether or not each is enabled
-n [tab]disable each NAME or display a list of disabled builtins
-p [tab]print the list of builtins in a reusable format
-s [tab]print only the names of Posix `special' builtins
Options controlling dynamic loading:
-f [tab]Load builtin NAME from shared object FILENAME
-d [tab]Remove a builtin loaded with -f
Without options, each NAME is enabled.
To use the `test' found in $PATH instead of the shell builtin
version, type `enable -n test'.
Exit Status:
Returns success unless NAME is not a shell builtin or an error occurs. |

Включение и отключение встроенных команд командного процессора.
Включает и отключает команды, встроенные в командный процессор. Отключение позволит
выполнить команду с диска, название которой совпадает с названием встроенной команды,
без указания полного пути к ней.
Параметры:
-a [tab]показать список встроенных команд и их состояние
-n [tab]отключить все указанные имена или вывести список отключённых команд
-p [tab]показать список встроенных команд
-s [tab]показать только названия встроенных команд «special» Posix
Параметры, управляющие динамической загрузкой:
-f [tab]загрузить встроенную указанную команду из указанного файла
-d [tab]удалить встроенную функцию, загруженную с параметром -f
Без указания параметров включаются все указанные команды.
Чтобы использовать команду «test», найденную в переменной $PATH,
а не встроенную в командный процессор, введите «enable -n test».
Состояние выхода:
Возвращает успех, если указанное имя не является встроенной командой или не произошла ошибка. |

Parse option arguments.
Getopts is used by shell procedures to parse positional parameters
as options.
OPTSTRING contains the option letters to be recognized; if a letter
is followed by a colon, the option is expected to have an argument,
which should be separated from it by white space.
Each time it is invoked, getopts will place the next option in the
shell variable $name, initializing name if it does not exist, and
the index of the next argument to be processed into the shell
variable OPTIND. OPTIND is initialized to 1 each time the shell or
a shell script is invoked. When an option requires an argument,
getopts places that argument into the shell variable OPTARG.
getopts reports errors in one of two ways. If the first character
of OPTSTRING is a colon, getopts uses silent error reporting. In
this mode, no error messages are printed. If an invalid option is
seen, getopts places the option character found into OPTARG. If a
required argument is not found, getopts places a ':' into NAME and
sets OPTARG to the option character found. If getopts is not in
silent mode, and an invalid option is seen, getopts places '?' into
NAME and unsets OPTARG. If a required argument is not found, a '?'
is placed in NAME, OPTARG is unset, and a diagnostic message is
printed.
If the shell variable OPTERR has the value 0, getopts disables the
printing of error messages, even if the first character of
OPTSTRING is not a colon. OPTERR has the value 1 by default.
Getopts normally parses the positional parameters, but if arguments
are supplied as ARG values, they are parsed instead.
Exit Status:
Returns success if an option is found; fails if the end of options is
encountered or an error occurs. |

Replace the shell with the given command.
Execute COMMAND, replacing this shell with the specified program.
ARGUMENTS become the arguments to COMMAND. If COMMAND is not specified,
any redirections take effect in the current shell.
Options:
-a name [tab]pass NAME as the zeroth argument to COMMAND
-c [tab]execute COMMAND with an empty environment
-l [tab]place a dash in the zeroth argument to COMMAND
If the command cannot be executed, a non-interactive shell exits, unless
the shell option `execfail' is set.
Exit Status:
Returns success unless COMMAND is not found or a redirection error occurs. |
