How to filter txt file by string with using batch
提问by Antediluvian
I know this kind of problem will be very easy for you but I am total beginner in batch mode.
我知道这种问题对你来说很容易，但我完全是批处理模式的初学者。
The question is how bat file code should look like to generate a new txt file from specific one .
问题是 bat 文件代码应该如何从特定的 .txt 文件生成新的 txt 文件。
for example .
例如 。
I have report txt
我有报告txt
Displaying status for license file: 7788@Server01
License Server: server01
License In Use Free
------- ------ ----
Design* 1 6
(user1@host1) 127 server01 7788 4402
Assembly* 0 4
Pro 0 15
AdvSE 2 3
(user2@host2) AdvSE server01 7788 2706
(user3@host3) AdvSE server01 7788 1503
SingleSite_License 1 3
(user4@host4) SingleSite_License server01 7788 2003
Intra_CLIENT_License 1 4
(user2@host2) Intra_CLIENT_License server01 7788 2003
CAD 1 32
^(user2@host2) CAD server01 7788 501
* = License Extensions - Available only on startup.
^ = Borrowed License.
Press any key to continue . . .
What I want to have in new file from this one are only lines :
我想在这个新文件中拥有的只有几行：
SingleSite_License 3
SingleSite_License 3
Intra_CLIENT_License 9
Intra_CLIENT_License 9
but both SingleSite_License and Intra_Client_License should be taken from 1st found string -other are not necessary.
但是 SingleSite_License 和 Intra_Client_License 都应该从第一个找到的字符串中获取 - 其他不是必需的。
report txt can be different and licenses can be showed in different order .
报告 txt 可以不同，许可证可以按不同的顺序显示。
if it not possible - other solution can be just only Free value will be written in new txt file - f.e 3 and 9 . so the last string in line which contains specific words
如果不可能 - 其他解决方案只能是 Free 值将写入新的 txt 文件 - fe 3 和 9 。所以包含特定单词的行中的最后一个字符串
thank you for any tips
谢谢你的任何提示

Not sure where you got the figure of 9for the Intra_CLIENT_License(souldn't it be 4?), but this script will print out the free licences for those two product codes:
不知道你在哪里得到的这个数字9为Intra_CLIENT_License（souldn't说，它是4？），但这个脚本会打印出了这两个产品代码的免费电视牌照：
@echo off
setlocal enableextensions enabledelayedexpansion
for /f "tokens=1,3" %%a in ('type infile.txt') do (
if "x%%a"=="xSingleSite_License" (
echo %%a %%b
)
if "x%%a"=="xIntra_CLIENT_License" (
echo %%a %%b
)
)
endlocal
I basically cut and pasted your transcript into the infile.txtfile and ran this script to get:
我基本上将您的成绩单剪切并粘贴到infile.txt文件中并运行此脚本以获取：
SingleSite_License 3
Intra_CLIENT_License 4
(you can replace type infile.txtwith whatever command you need to generate that output).
（您可以替换type infile.txt为生成该输出所需的任何命令）。
Breakdown:
分解：
The setlocaljust sets up cmd.exeto allow extensions and delayed expansion of environment variables. All my scripts start with this since it's so useful.
在setlocal刚刚设置了cmd.exe允许扩展和环境变量的延迟扩展。我所有的脚本都以此开头，因为它非常有用。
The forloop basically processes one line at a time, grabbing tokens 1 and 3 (aand b) from each.
该for循环基本上一次处理一行，从每个中获取标记 1 和 3（a和b）。
Then it's a simple matter of checking afor the required licence values and, if it matches, outputting that along with b.
然后检查a所需的许可证值是一个简单的问题，如果匹配，则将其与b.

Write a C application. Batch is unnecessarily kludgy and probably can't even do this kind of stream manipulation.
编写一个 C 应用程序。Batch 是不必要的混乱，甚至可能无法进行这种流操作。
