Execute shell builtins.
Execute SHELL-BUILTIN with arguments ARGs without performing command
lookup. This is useful when you wish to reimplement a shell builtin
as a shell function, but need to execute the builtin within the function.
Exit Status:
Returns the exit status of SHELL-BUILTIN, or false if SHELL-BUILTIN is
not a shell builtin.. |
|
|

Start a new line in the equivalent position in the translation.

执行 shell 内建。
带参数 ARGs 执行 SHELL-BUILTIN 内建，并且不做命令查询
在希望以 shell 函数的形式来重新实现 shell 内建，
并且希望在函数之内执行该 shell 内建的情况下有用处。
退出状态：
以 SHELL-BUILTIN 内建的退出状态为准，或者如果 SHELL-BUILTIN不是一个 shell 内建时
为假。. |

Return the context of the current subroutine call.
Without EXPR, returns "$line $filename". With EXPR, returns
"$line $subroutine $filename"; this extra information can be used to
provide a stack trace.
The value of EXPR indicates how many call frames to go back before the
current one; the top frame is frame 0.
Exit Status:
Returns 0 unless the shell is not executing a shell function or EXPR
is invalid. |

返回当前子例程调用的上下文。
不带有 <表达式> 时，返回 "$line $filename"。带有 <表达式> 时，
返回 "$line $subroutine $filename"；这个额外的信息可以用来提供
栈跟踪 (stack trace)。
<表达式> 的值表示从当前调用帧需要回去多少个调用帧；栈顶帧是第 0 帧。
退出状态：
返回 0，除非 shell 不在执行一个 shell 函数，或者 <表达式> 无效。 |

Change the shell working directory.
Change the current directory to DIR. The default DIR is the value of the
HOME shell variable.
The variable CDPATH defines the search path for the directory containing
DIR. Alternative directory names in CDPATH are separated by a colon (:).
A null directory name is the same as the current directory. If DIR begins
with a slash (/), then CDPATH is not used.
If the directory is not found, and the shell option `cdable_vars' is set,
the word is assumed to be a variable name. If that variable has a value,
its value is used for DIR.
Options:
-L [tab]force symbolic links to be followed
-P [tab]use the physical directory structure without following symbolic
[tab]links
-e [tab]if the -P option is supplied, and the current working directory
[tab]cannot be determined successfully, exit with a non-zero status
The default is to follow symbolic links, as if `-L' were specified.
Exit Status:
Returns 0 if the directory is changed, and if $PWD is set successfully when
-P is used; non-zero otherwise. |

[tab] represents a tab character.
Please write it exactly the same way, [tab], in your

Print the name of the current working directory.
Options:
-L [tab]print the value of $PWD if it names the current working
[tab]directory
-P [tab]print the physical directory, without any symbolic links
By default, `pwd' behaves as if `-L' were specified.
Exit Status:
Returns 0 unless an invalid option is given or the current directory
cannot be read. |

打印当前工作目录的名字。
选项：
-L [tab]打印 $PWD 变量的值，如果它命名了当前的
[tab]工作目录
-P [tab]打印当前的物理路径，不带有任何的符号链接
默认情况下，`pwd' 的行为和带 `-L' 选项一致
退出状态：
除非使用了无效选项或者当前目录不可读，否则
返回状态为0。 |

Execute a simple command or display information about commands.
Runs COMMAND with ARGS suppressing shell function lookup, or display
information about the specified COMMANDs. Can be used to invoke commands
on disk when a function with the same name exists.
Options:
-p [tab]use a default value for PATH that is guaranteed to find all of
[tab]the standard utilities
-v [tab]print a description of COMMAND similar to the `type' builtin
-V [tab]print a more verbose description of each COMMAND
Exit Status:
Returns exit status of COMMAND, or failure if COMMAND is not found. |

Set variable values and attributes.
Declare variables and give them attributes. If no NAMEs are given,
display the attributes and values of all variables.
Options:
-f [tab]restrict action or display to function names and definitions
-F [tab]restrict display to function names only (plus line number and
[tab]source file when debugging)
-g [tab]create global variables when used in a shell function; otherwise
[tab]ignored
-p [tab]display the attributes and value of each NAME
Options which set attributes:
-a [tab]to make NAMEs indexed arrays (if supported)
-A [tab]to make NAMEs associative arrays (if supported)
-i [tab]to make NAMEs have the `integer' attribute
-l [tab]to convert NAMEs to lower case on assignment
-r [tab]to make NAMEs readonly
-t [tab]to make NAMEs have the `trace' attribute
-u [tab]to convert NAMEs to upper case on assignment
-x [tab]to make NAMEs export
Using `+' instead of `-' turns off the given attribute.
Variables with the integer attribute have arithmetic evaluation (see
the `let' command) performed when the variable is assigned a value.
When used in a function, `declare' makes NAMEs local, as with the `local'
command. The `-g' option suppresses this behavior.
Exit Status:
Returns success unless an invalid option is supplied or an error occurs. |
