比较批处理脚本中的两个数字 [英] Comparing two number in batch script

问题描述

如果这似乎是一个非常基本的问题，我很抱歉，但是我无法比较在批处理脚本中连续写入一个文件的两个文件大小，它不会超出 if 语句，只是卡在那里然后没有做任何事.

I'm sorry if it seems a very basic question, but I cant compare two file sizes where one file is being written continuously in batch script, it doesn't go beyond if statement, just get stuck there and comes out without doing anything.

:START
 copy C:UsersAdminping.txt C:UsersAdminping.partial
 set file="C:UsersAdminping.txt"
 set parfile="C:UsersAdminping.partial"
 ping -n 5 127.0.0.1 > nul
 FOR %%A IN (%file%) DO set size=%%~zA
 FOR %%B IN (%parfile%) DO set parsize=%%~zB
 echo %size%
 echo %parsize%
 if %size% EQU %parsize%
 (
   ECHO file is complete > C:UsersAdminstatus.log
   ping -n 5 127.0.0.1 > nul
 )
 else 
 (      
  echo incomplete > C:UsersAdminstatus.log
  ping -n 5 127.0.0.1 > nul
   goto start
   )

我在这里做错了什么.:(

What I'm doing wrong here. :(

推荐答案

if cond ( 
...
) else (
...
)

if cond (...) else (...)
if cond (...) else command
if cond (...) else (
    ....
)
if cond (
    ....
) else command

括号的位置很重要.if 左括号需要与 if 命令在同一行.if 右括号需要与 else 子句(如果存在)在同一行.else 左括号需要与 else 子句在同一行.

The placement of the parenthesis matters. The if opening parenthesis needs to be on the same line that the if command. The if closing parenthesis needs to be in the same line that the else clause (if present). The else opening parenthesis needs to be in the same line that the else clause.
