将文件输出存储到变量中

发布于 2024-10-10 02:49:23 字数 298 浏览 0 评论 0原文

我想将文本文件的输出存储到一个变量中，这样我就可以将整个文件作为参数传递。

我使用的是 Windows 2003 Server。

文本文件有多行，例如：

10.20.210.100 fish
10.20.210.101 rock

我正在使用：

Set /P var=<file.txt

它仅读取文件的第一行。

我也尝试使用 FOR 循环，但它只将最后一行分配给变量。

I want to store the output of text file into a variable, so I can pass the whole file as parameter.

I am using Windows 2003 Server.

The text files have multiple lines like:

10.20.210.100 fish
10.20.210.101 rock

I was using:

Set /P var=<file.txt

It reads only the first line of the file.

I tried with FOR loop also but it assigned only the last line to the variable.

没有一种简单的方法可以将文件的完整内容放入一个变量中。
变量的长度限制为 ~8100。
将 CR/LF 放入变量中很复杂，

但是使用 FOR 循环，您可以获得每一行。

尝试查看批处理脚本逐行读取

编辑：
要获取单个变量中的每一行，您可以使用它

@echo off
SETLOCAL EnableDelayedExpansion
set n=0
for /f "delims=" %%a IN (example.txt) do (
  set /a n+=1
  set "line[!n!]=%%a"
  echo line[!n!] is '%%a'
)
set line

或仅获取一个变量中的所有内容（不带 CR/LF）

@echo off
SETLOCAL EnableDelayedExpansion
set "line="
for /f "delims=" %%a IN (example.txt) do (
  set "line=!line! %%a"
)
echo !line!

There is no simple way to get the complete content of a file into one variable.
A variable has a limit of ~8100 length.
And it is complicated to get CR/LF into a variable

But with a FOR-loop you can get each single line.

Try a look at batch script read line by line

EDIT:
To get each line in a single variable you can use this

@echo off
SETLOCAL EnableDelayedExpansion
set n=0
for /f "delims=" %%a IN (example.txt) do (
  set /a n+=1
  set "line[!n!]=%%a"
  echo line[!n!] is '%%a'
)
set line

or to get all in only one variable (without CR/LF)

@echo off
SETLOCAL EnableDelayedExpansion
set "line="
for /f "delims=" %%a IN (example.txt) do (
  set "line=!line! %%a"
)
echo !line!

Jeb 的脚本运行完美，但是如果您 echo %line% 它包含文件时间中的每一行。如果你使用 echo !Line! ，它包含一行！也与其他线路。我对脚本做了一些修改，现在得到了预期的结果。

@echo off
SETLOCAL EnableDelayedExpansion
set "line="
for /f "delims=" %%a IN (example.txt) do (
set "line1=%%a"
set "line=!line1! and  %%a"
)
echo !line!

或者

echo %line%

现在您将在机器人案例中得到相同的结果。

Jeb’s script is working perfect, But if you echo %line% it contains each line no of line in file times. And if you use echo !Line! ,it contain one !line! also with other line. I did a little modification in script and now I am getting expected result.

@echo off
SETLOCAL EnableDelayedExpansion
set "line="
for /f "delims=" %%a IN (example.txt) do (
set "line1=%%a"
set "line=!line1! and  %%a"
)
echo !line!
