我有一个Output.txt
文件,其中包含以下内容:
Server1
APPNAME MEMORY
WINDOWS 54896378
LINUX 78542
MACOS 187963
Server2
APPNAME MEMORY
DATABASE 587412369
SCHEMA 78542
TABLESPACE 187963
我想创建一个批处理脚本,搜索Output.txt中的所有数值(如54896378,78542,78542等),并将它们除以1024 * 1024,以便在BYTES的Newoutput.txt文件内存中更改为MB
我在下面尝试但没有得到我想要的东西:
@echo off
setlocal enabledelayedexpansion
for /F "delims= " %%a in ('findstr "[1-9][0-9]* 0"' Output.txt) do (
SET /A Result = %a / 1024*1024 > Newoutput.txt
)
EDIT1 :
当Output.txt
文件具有以下内容时,一切正常,但脚本不会仅转换FreePhysicalMemory
值6621212,即:
Output.txt的:
Server1
APPNAME MEMORY
WINDOWS 54896378
LINUX 78542
MACOS 187963
FreePhysicalMemory TotalVisibleMemorySize
6621212 8387172
Newoutput.txt:
Server1
APPNAME MEMORY
WINDOWS 13.58
LINUX 2.45
MACOS 1.8
FreePhysicalMemory TotalVisibleMemorySize
6621212 21.4
我们需要在脚本中进行哪些更改..?
答案 0 :(得分:3)
SET /A Result = %a / 1024*1024
这将%a除以1024并将输出乘以1024.这不是你想要的。 正确的划分应该是:
SET /A Result = %a / 1024 / 1024
或者您可以预先计算1024 * 1024 = 1048576和
SET /A Result = %a / 1048576
答案 1 :(得分:3)
请注意,批处理仅适用于整数。您的一些计算将导致0 MB的值。以下是如何使用十进制值的粗略示例。
@echo off
