从WMIC输出中删除回车

时间:2013-10-19 22:04:22

标签: batch-file

在批处理文件中使用下面的命令,我得到输出,但随着回车一起返回一些回声。

wmic process where Caption='notepad.exe' get ProcessId,WorkingSetSize /Format:Texttable > output.txt

输出:

ProcessId  WorkingSetSize  
4016       6356992         
1548       6189056         

如何摆脱输出中的回车?

EDIT1:

参考Foxdrive在我的链接问题中的工作答案我在下面尝试并且工作得很好,但在输出中有一个额外的行: ECHO关闭。不知道为什么?

@echo off
setlocal enabledelayedexpansion
(For /F "tokens=1,* delims==" %%A in (' "wmic process where Caption='notepad.exe' get ProcessId,WorkingSetSize /Format:Texttable" ') do (
set "line=%%A %%B"
set "line=!line:~0,-1!"
echo !line!
))>output.txt

output.txt的:

ProcessId  WorkingSetSize  
4768       6365184         
5608       5500928         
2888       6037504         
1052       5472256         
ECHO is off.

EDIT2:

ProcessId  WorkingSetSize  
    4768       6365184         
    5608       5500928         
    2888       6037504         
    1052       5472256  

我只希望以上述格式输出并使用以下方式获取输出:

@echo off
setlocal enabledelayedexpansion
(For /F "delims=" %%A in ('"wmic process where Caption='notepad.exe' get  ProcessId,WorkingSetSize /format:Texttable |findstr "[0-9P]" "') do (
set "line=%%A"
echo !line:~0,-1!
)) > output.txt

现在输出中是否有任何尾随CR? hexdump命令在我的系统中不起作用.. :( ..将非常感谢您的确认.. :)

试试这个:

wmic process where Caption='notepad.exe' get ProcessId,WorkingSetSize /Format:Texttable|findstr /v "^$">file.txt

输出(Windows 8) FAR FROM'HORRIBLE'

这将删除尾随CR并提供以空格分隔的值:

@echo off
setlocal enabledelayedexpansion
(For /F "tokens=2,3 delims=," %%a in ('"wmic process where Caption='notepad.exe' get ProcessId,WorkingSetSize /format:csv |findstr "[0-9]" "') do (
set "num=%%b"
echo %%a !num:~0,-1!
))>output.txt

该文件采用以下格式:

624 4923392
9220 4886528

这将删除尾随CR并以CSV格式提供值

@echo off
setlocal enabledelayedexpansion
(For /F "delims=" %%A in ('"wmic process where Caption='notepad.exe' get ProcessId,WorkingSetSize /format:csv |findstr "[0-9]" "') do (
set "line=%%A"
echo !line:~0,-1!
))>output.txt

这是文件所在的格式:

PCNAME,956,4960256
PCNAME,4004,4870144

我没有运行代码的额外CR或aditional回声。但是既然你得到了它们,Endoro的答案已经足够接近了。而不是尝试过滤不想要的行,尝试只获取您感兴趣的行

wmic ..... ^| findstr /B /R "[0-9P]"

仅以数字(数据)或P(ProcessId)

开头的行
