New line as a delimeter of FOR loop

阅读更多关于 New line as a delimeter of FOR loop

问题 I am new to batch script, and I am trying to parse a file that has key value (kind) of pairs delimited by new line. For example: the value of abc 1234 the value of def 5678 the value of ghi 9876 I would like to read this file using new line as delimited so that I can access the values. Something like for /f "tokens=1,2,3 delims='\n'" %%i in ('findstr /C:the value of abc 'filepath') do echo %%j 回答1: You can't set 'new line' as delimiter. Try this: @echo off &setlocal for /f "tokens=1*delims=:"

SET Command - Floating point numbers?

阅读更多关于 SET Command - Floating point numbers?

问题 How do I use the SET command in windows for floating point arithmatic. /A stands for arithmetic and %VAR% prints the data of VAR not the name. For example when I do: SET /A VAR="2.5+3.1" ECHO %VAR% pause I get the error: 'Missing Operator'. The output (5.6) should be converted to floating point too I'm still busy learning the basic syntax. Regards, Snipe 回答1: The arithmetic operations of SET /A command are performed over 32-bits integer numbers only; however, you may easily simulate fixed

问题 When running the VBS unzip code batch in Win 10, I'm getting the error below. What can be a reason for this, given it was reported working before by others? Changing target directories or explicitly setting them doesn't affect the error. @echo off setlocal enabledelayedexpansion cd /d %~dp0 set vbs="%temp%\_.vbs" call :UnZipFile "E:\Temp\" "%USERPROFILE%\Downloads\archive.zip\" exit /b :UnZipFile <ExtractTo> <newzipfile> if exist %vbs% del /f /q %vbs% >%vbs% echo Set fso = CreateObject(

How to kill a process based on its image / file path?

阅读更多关于 How to kill a process based on its image / file path?

问题 How to kill a task based on the path of the executable? The usage of taskkill /F /IM "app.exe" doesn't work in this case because there are other programs running that have the same image/process/file name, but are totally different executables. The paths are different and the .exe files with same file name are different, too. Something like "taskkill /F /IM "C:\path\to\exe\app.exe" would be ideal. 回答1: Using WMIC , as suggested in the comments by Squashman, you can do it as a single command:

Batch: How to export yesterday's date keeping format [mm/dd/yyyy]?

阅读更多关于 Batch: How to export yesterday's date keeping format [mm/dd/yyyy]?

问题 I am trying to create an environment variable for yesterday's date. It MUST be in the format of MM/DD/YYYY . For code I currently have: set m=%date:~-7,2% set /A m -= 1 set DATE_YESTERDAY=%date:~-10,2%/%m%/%date:~-4,4% echo %DATE_YESTERDAY% This works great, HOWEVER, when I offset to yesterdays day with -1 instead of " 12/03/2019 " I get " 12/3/2019 ". Thus, missing the zero/0. Any ideas to keep format as MM/DD/YYYY ? I have seen many other questions regarding this, however, all come short!

Save output from FIND command to variable

阅读更多关于 Save output from FIND command to variable

问题 Like the title says, I'm trying to take the output from a FIND command and save it to a variable. Specifically, I'm using: DIR /b /s "C:\" | FIND "someexe.exe" to locate a specific .exe file, which seems to work fine, but then I want to save the results of FIND to use later in the same script. I've tried various different tweaks of: for /f "usebackq" %%i in (`DIR /b /s "C:\" | FIND "someexe.exe"`) do SET foobar=%%i but when I try to run the script the command window immediately closes

阅读更多关于 How can I split a binary file into chunks with certain size with batch script without external software?

问题 There are many reasons to want to split file into chunks - mainly for network transfer (e.g. e-mail attachments) but I'm sure there are scenarios that could require such thing I cannot imagine. So how can a file be split into chunks that can be easily assembled back to original file (including non-windows systems) ? What are possibilities: MAKECAB - the built-in Windows archiver - it can compress file and split it , but will be difficult to assemble the file on non-Windows machine. WSH
