首先欢迎各位DOS爱好者进入中国DOS联盟批处理室学习讨论问题.
如果你刚刚注册帐号,请阅读这篇文章,它可以使你避免很多不必要的/重复的提问和发贴.
如果你是刚来的新手,我先提几点小小的要求吧:
1、发贴求助之前请先搜索一下论坛，因为你提的问题可能早就被解决了至少不止一次了；
2、如果经过了自己的思考和搜索仍然没有解决自己的问题，那么就发求助贴，千万要注意标题要表达贴子的主要意思，这样才有更多的人来关注你的问题；
3、切忌在论坛里面侮辱他人人格，违反版规。

First of all, welcome all DOS enthusiasts to enter the batch processing room of the China DOS Union to study and discuss issues.
If you have just registered an account, please read this article, which can help you avoid many unnecessary/repeated questions and posts.
If you are a new user just arriving, I will put forward a few small requirements:
1. Before posting for help, please search the forum first, because the problem you raise may have been solved at least more than once;
2. If after your own thinking and searching, you still haven't solved your problem, then post a help post. Be sure to pay attention that the title should express the main meaning of the post, so that more people will pay attention to your problem;
3. Do not insult the personality of others in the forum, which violates the forum rules.
Question0:
Experts, please come in!
Urgent!!!!!!!!!!
Kneeling to beg!!
Who can help me????
A very difficult problem!
Answer:
If the title of your post is like this, you can first take a look here:
http://www.cn-dos.net/forum/viewthread.php?tid=1415
Question1:
I see that there are many symbols in many batch processing codes, such as (% ^ |! ~), I don't know what their specific functions are?
Answer:
If you encounter a problem about symbols, you can refer to the following:
http://www.cn-dos.net/forum/viewthread.php?tid=30985
Question2:
What does a statement like "%date:~0,10%" mean?
Answer:
This is a variable intercepting function of CMD, which can intercept the characters at the specified position of the variable. For the specific usage, you can refer to the following post:
http://www.cn-dos.net/forum/viewthread.php?tid=25746
Question3:
What is variable delay, and what is the use of "Setlocal EnableDelayedExpansion" in batch processing?
Answer:
Refer to the following two posts, and I believe you will have a certain understanding of variable delay:
http://www.cn-dos.net/forum/viewthread.php?tid=20733
http://www.cn-dos.net/forum/viewthread.php?tid=28273
Question4:
The for command is so difficult, how to use it specifically?
Answer:
After carefully reading the following several posts, you will definitely master the common usages of the for command:
http://www.cn-dos.net/forum/viewthread.php?tid=19331
http://www.cn-dos.net/forum/viewthread.php?tid=13592
http://www.cn-dos.net/forum/viewthread.php?tid=33751
There are many posts with the use of for. If you have been lurking long enough, you will definitely master the usage of for!
Question5:
What does %%~fa in the for command mean?
Answer:
Enter for /? in the command line and look at the last part.
PS: The usage of many commands is included in their own help documents. As long as you read them carefully, you will definitely learn a lot.
Question6:
How to create an empty file?
Answer:
http://www.cn-dos.net/forum/viewthread.php?tid=22336
Question7:
How does batch processing execute a command after delay?
Answer:
http://www.cn-dos.net/forum/viewthread.php?tid=23475#pid140849
Question8:
What is redirection?
Answer:
http://www.cn-dos.net/forum/viewthread.php?tid=16942#pid115734
Question9:
The batch processing prompts that wget, sed or gawk are not internal commands or external commands. What should I do?
Answer:
wget, sed and gawk are all third-party tools. They need to be downloaded and placed in the system search path or the current directory to run. You can download them from the following special attachment post:
http://www.cn-dos.net/forum/viewthread.php?tid=25914
Question10:
What does set string=%string:AAA=BBB% mean?
Answer:
This is the character replacement function of cmd, that is, replacing the character "AAA" in the variable "string" with "BBB".
Question11:
What does "gtr" mean in if %str% gtr 255 command?
Answer:
This is the comparison operator of if:
EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal
