BATCH / CMD：将.txt的每一行打印到变量中 [英] BATCH/CMD: Print each line of a .txt into a variable
问题描述
目标：将计算机中的每个dll文件传递到regsvr32.exe
Goal: Have every dll file in a computer passed into regsvr32.exe
完成：
cd\
:: REM将每个文件和目录（/ s）导出到c：的根目录中的文件（仅包含文件名（/ b）的dir.txt）
dir / s /b>>dir.txt
:: REM现在，这将包含每个扩展类型。我们只需要dll，所以我们找到dll.txt：
findstr.dll $dir.txt >> dll.txt
Accomplished:
cd\
::REM Exports every file and directory (/s) into a file in root of c: called dir.txt with only file names (/b)
dir /s /b>>dir.txt
::REM Now, this will contain every extension type. We only want dll's, so we findstr it into dll.txt:
findstr ".dll$" dir.txt>>dll.txt
扭结：
现在，如果我想regsvr32.exe文件每个文件，现在在dll.txt，我不知何故需要得出每个单独的文件名是单独在每行上。我想知道是否有第三方命令行工具，可以导出文件的每一行到一个变量。这样，我可以：
Now, if I want to regsvr32.exe "file" every file that is now in dll.txt, I somehow need to get out every individual filename that is individually on each line. I was wondering if there is a third party command line tool that can export each line of the file into a variable. This way, I could:
==========
==========
这个工具有行号的开关/ l，和使用变量的/ v：，结尾使用file：
::REM assume this tool had switches /l for the line number, and /v:"" for variable to use, and used "file" at the end:
set line=1
:loop
set dll=
tool.exe /l %line% /v:"dll" "dll.txt"
::REM We if defined here because if the line doesn't exist in dll.txt, the tool would return nothing to %dll%
if not defined %dll% exit
::REM With the variable defined, we can continue
regsvr32.exe %dll%
set /a line=%line%+1
goto loop
=====================
=======================
然后工具将处理文件的每一行的每个路径，直到它自动退出，因为将没有更多的行。循环后的注意事项我将dll设置为无，这样'如果未定义'将每次都会工作。
Then the tool would process each path of each line of the file until it exits automatically, because there would be no more lines. Notice right after loop I set dll to nothing so that 'if not defined' will work each time.
如果这种类型的第三方工具无法完成，一个方法做到这一点？
If this type of third-party tool cannot be done, is there a way to do that with for?? I honestly never learned for, and tried to but could never figure it out.
任何帮助都非常感谢！
如果这已经回答了，很抱歉。

EDIT / UPDATE：
我发现了如何使这项工作。

第一个链接显示手动替换开头的regsvr32.exe
第二个显示如何使用在这种情况下{也感谢craig65535为他的帮助：}}
The first link shows manually replacing the beginning with regsvr32.exe
The second shows how to use for in this case {also thanks to craig65535 FOR his help :)}

推荐答案
for /f %%f in ('type dll.txt') do regsvr32.exe %%f
code>键入dll.txt ，并在 %% f 中一次输入一行。然后，您可以使用 %% f 作为其他命令的参数。
That takes the output of type dll.txt and puts one line at a time into %%f. You can then use %%f as an argument for some other command.
regsvr32.exe %% f ，您可以写另一个批处理文件并调用：
If you want to do more than regsvr32.exe %%f, you can write another batch file and call that:
for /f %%f in ('type dll.txt') do call process.bat %%f
b $ b
process.bat会接收到％1 的文件名。
