在环境变量Windows控制台宽度 [英] Windows console width in environment variable

问题描述

我怎样才能获得Windows控制台的当前宽度在一个批处理文件中的环境变量？

How can I get the current width of the windows console in an environment variable within a batch file?

推荐答案

我喜欢使用Windows内置的模式命令的办法。
请尝试以下批处理文件：

I like the approach using the built-in mode command in Windows. Try the following batch-file:

@echo off
for /F "usebackq tokens=2* delims=: " %%W in (`mode con ^| findstr Columns`) do set CONSOLE_WIDTH=%%W
echo Console is %CONSOLE_WIDTH% characters wide

注意，这将返回在控制台缓冲区的大小，而不是窗口的大小（这是可滚动）。

Note that this will return the size of the console buffer, and not the size of the window (which is scrollable).

如果你想在Windows控制台的高度，你可以替换列在 FINDSTR 前pression与行。再次，它会返回缓冲区，而不是窗口的高度......我个人希望有一个大的缓冲区以允许通过滚动历史回来，所以对我行通常会报告3000：）

If you wanted the height of the windows console, you can replace Columns in the findstr expression with Lines. Again, it will return the height of the buffer, not the window... I personally like to have a big buffer to allow scrolling back through history, so for me the Lines usually reports about 3000 :)

只是为了好玩，这里的 FINDSTR A版不使用过滤输出...的情况下，（由于某种原因）你有<$的厌恶C $ C> FINDSTR ：

Just for fun, here's a version that doesn't use findstr to filter the output... in case (for some reason) you have a dislike of findstr:

@echo off
for /F "usebackq tokens=1,2* delims=: " %%V in (`mode con`) do (
    if .%%V==.Columns (
        set CONSOLE_WIDTH=%%W
        goto done
    )
)
:done
echo Console is %CONSOLE_WIDTH% characters wide

请注意，这是所有试图在Windows XP SP3，在许多不同的窗口（包括一名执行经理FAR）的。

Note, this was all tried in Windows XP SP3, in a number of different windows (including one executing FAR manager).
