批量输出，每个字符串后都有空格 [英] batch outputting with space after each string

问题描述

嘿，我目前有这段代码可以将来自不同文本文件的不同文本转换为变量，然后输出为一个文件:

Hey i currently have this code to turn different text from different text files into variables then output into one file:

@echo off
echo system starting..
cls
echo grabbing versions 
cd C:\Scripts\Bamboo
FOR /F "tokens=1 delims==" %%n IN (CurrentBuild.txt) DO SET build-version-number=%%n
cd C:\Users\Administrator\bamboo-home\xml-data\build-dir\MC-CC-MAIN
FOR /F "tokens=1 delims==" %%n IN (MinecraftVersion.txt) DO SET minecraft-version-number=%%n
FOR /F "tokens=1 delims==" %%n IN (ForgeVersion.txt) DO SET forge-version-number=%%n
FOR /F "tokens=1 delims==" %%n IN (ModVersion.txt) DO SET mod-version-number=%%n
cls
echo setting versions to variables
set mod-version=mod_version = %mod-version-number%
set forge-version=forge_version = %forge-version-number%
set build-version=build_version = %build-version-number%
set minecraft-version=minecraft_version = %minecraft-version-number%
cls
echo outputing variables to build.properties
del build.properties
@echo %minecraft-version% >> build.properties
@echo %forge-version% >> build.properties
@echo %mod-version% >> build.properties
@echo %build-version% >> build.properties
cls
echo done, exiting inject script 
exit

但是输出中的每个空格后面都有空格(whitline):

but the output has spaces (whitline) after each one:

"minecraft_version = 1.7.10 "
"forge_version = 10.13.2.1291 "
"mod_version = v1.0 "
"build_version = 33 "

不确定为什么会这样.

推荐答案

它是>或>>重定向器之前的空间.删除它如下(关于 dbenham的有益评论进行的编辑):

It is the space preceding the > or >> redirector. Remove it as follows (edited in regard of dbenham's benefitting comment):

(@echo %minecraft-version%)>> build.properties

或

>> build.properties (@echo %minecraft-version%)

说明:

如果变量%minecraft-version% 以单个数字结尾结束，则
• @echo %minecraft-version%>> build.properties可能会中断输出；
• >> build.properties @echo %minecraft-version%不够用，因为该行可能包含不需要的(被遗忘的)尾随空格.

• @echo %minecraft-version%>> build.properties could break output if the variable %minecraft-version% ends with a single digit preceded with a space;
• >> build.properties @echo %minecraft-version% does not suffice as the line could contain an unwanted (forgotten) trailing space.

此外，要完全控制变量名和值中的前导和尾随空格，请在set命令中使用双引号，如下所示:

Moreover, to keep full control on leading and trailing spaces in variable names and values, use double quotes in set command as follows:

set "variable=value"

思考其他人:

set "variable= this value contains a leading space"
set "variable= this value surrounded with spaces "
set "variable=this value contains a trailing space "
set "variable =this variable name contains a trailing space"

已应用于脚本中的某些命令:

Applied to some commands in your script:

FOR /F "tokens=1 delims==" %%n IN (ModVersion.txt) DO SET "mod-version-number=%%n"
:::
set "mod-version=mod_version = %mod-version-number%"

等
