学习计算机需要多少单词？

最近开发了一个翻译程序，效果如下：

一、输入英文文档

                                                Commands Reference, Volume 2, d - h

env Command

Purpose

       Displays the current environment or sets the environment for the execution of a command.

Syntax

To Display Multiple Environment Variables

       env [ -i | - ] [Name=Value ]... [Command [ Argument ... ] ]

To Display A Single Environment Variable

       env [Name]

Description

       The env command allows you to display your current environment or run a specified command in a changed environment.

       If no flags or parameters are specified, the env command displays your current environment, showing one Name=Value pair per
       line.

Flags

       -i
            Ignores the inherited environment and invokes the command specified by the Command parameter with the environment
            specified by the Name=Value parameters.

Parameters

       Name=Value
            You can run a command in a modified version of the current environment by specifying one or more Name=Value parameters.
            Use the -i flag if you wish to replace the entire current environment with the specified Name =Value parameters. In
            either case, environment changes are effective only while the specified command is running.
       Command
            The Command parameter has an optional Argument variable. If the specified command is one of the Korn shell special
            built-in commands, results are unspecified. Korn shell built-in commands are described in the ksh command.

Exit Status

       If the Command parameter is specified, the exit status of the env command is the exit status of the command specified in the
       Command parameter. Otherwise, the env command exits with one of the following values:
       0
            The env command completed successfully.
       1-125
            An error occurred in the env command.
       126
            The command specified by the Command parameter was found, but could not be invoked.
       127
            The command specified by the Command parameter was not found.

Examples
       1    To change the TZ environment variable while running the date command, type:

            TZ=MST7MDT date

            OR

            env TZ=MST7MDT date

            Each of these commands displays the time in mountain time and the current date. The two commands shown are equivalent.
            When the date command is finished, the previous value of the TZ environment variable takes effect again.
       2    To run the make command in an environment that consists only of definitions for the PATH, IDIR, and LIBDIR environment
            variables, type:

            env -i PATH=$PATH IDIR=/$HOME/include LIBDIR=/$HOME/lib make

            You must specify the PATH environment variable so that the shell can find the make command. When the make command is
            finished, the previous environment takes effect.

Files

       /usr/bin/env
            Contains the env command.

            When the date command is finished, the previous value of the TZ environment variable takes effect again.
