I want to make a BAT to add a local account, but I don't know how to modify the "password never expires" option in the command line.

My CMD is net user qgp password/add /active:yes /expires:never /passwordchg:no /passw
ordreq:yes

By the way, how to operate if using IF to judge whether the qgp user exists. Thanks.

Netuser is a freeware command line / batch program that will rename a user account.

usage: netuser username <settings>

<settings>:

download from here
http://www.jsifaq.com/dl/netuser.zip

/name:newname
/pwnexp:{y|n} sets Password Never Expires

Examples:

netuser Administrator /name:"My Domain Admin"

netuser "John Doe" /name:DoeJ

1、net user qgp password/add /active:yes /expires:never /passwordchg:no /passwordreq:yes

Among them, the part in red is the option to modify that the password never expires. Its value can be never, or a specific date can be specified, meaning it expires on that day, such as 10/10/08.

2、You can use an if judgment to implement checking whether the qgp user exists.

@echo off for /f %%i in ('net user ^| find "qgp"') do ( if not "%%i#"=="#" echo There is the qpg user. & goto :lxm ) echo The qgp user does not exist. :lxm pause

But this code has certain limitations. If there is also a system account named qgpabc, it will also report that this user exists.

The functions of this for and if are really powerful. You can't understand them thoroughly without trying them several more times.

Two codes to determine if an account exists:



Code that will never go wrong:



@echo off

net user qgp >nul 2>nul && echo The user exists || echo The user does not exist.

pause



Code with certain limitations:



@echo off

set trom=1

for /f "skip=4 tokens=1-3" %%i in ('net user') do (

    if not "%%i"=="" if not "%%i"=="The command completed successfully." if "%%i"=="qgp" echo The user exists. & set trom=2 

    if not "%%j"=="" if "%%j"=="qgp" echo The user exists. & set trom=2 

    if not "%%k"=="" if "%%k"=="qgp" echo The user exists. & set trom=2 

)

if "%trom%"=="1" echo The user does not exist.

pause

Brother pengfei's ideas are indeed broad. The "net user qgp >nul 2>nul" in the first code and the use of "&&" and "||" are quite clever, and the second code is also a relatively novel idea~

Correct that EXPIRES is the account expiration time, not the password expiration option.

Brother pengfei, can you explain your first code segment?

The first piece of code is very simple, which is to use net user to list users. If the user exists, it will execute successfully; otherwise, it returns 2. Making use of this, we can very accurately judge whether the user exists.

And the algorithm of the second piece of code is to list all user names and then judge whether the user exists. The limitation here is that if the user name has a space, it will prompt that the user does not exist.

Pengfei's explanation is too classic.

@echo off
echo Testing your network...
ping www.google.com -n 2 >nul 2>nul && echo Site1 is online || echo Site1 network down

ping www.go12ogle.com -n 2 >nul 2>nul && echo Site2 is online || echo Site2 network down

Pause

Everyone can use this code for testing.

And the second...

　　Hehe, I tried it. I can't create a user with a space character in CMD, but I can in lusrmgr.msc.
　　
　　It seems that what Windows can do is not necessarily achievable in CMD.``

The user name and the full user name are different.

RE: he200377

　　Hehe, thanks for the reminder, forgot that it can also be enclosed in quotes. It seems I haven't done enough testing.
