[文件操作] 批处理如何替换文件中的星号*特殊符号？

xiaopingln

求助：

用set 替换一个文件里面的特殊字符 *替换为空格

比如文件里面有一大堆字符串： “23423回来日3咽螺距3是啊kljsdfsjf;ajs;fdjsafjsklfjklsdjfklsjfklj3kl*.cnkljdsflkklfsj*.cnkljdfkjdfjdlkjkl*.com”

把*.cn 替换成空格

pcl_test

::先下载http://batch-cn.qiniudn.com/tool/4.0.7/sed.exe
sed -i "s/\*\.cn/ /g" "a.txt"
复制代码

pcl_test

@echo off
set "file=a.txt"
>$ (mshta "javascript:with(new ActiveXObject('Scripting.FileSystemObject')){GetStandardStream(1).Write(GetStandardStream(0).readall().replace(/\*\.cn/g,' '));close()}"|find /v "")<"%file%"
move $ "%file%"
pause
复制代码

CrLf

1>1/* :
@echo off
cscript -nologo -e:jscript "%~f0" <a.txt >$
move $ "%file%"
pause & exit /b
*/
WSH.Echo(WSH.StdIn.ReadAll().replace(/\*\.cn/ig,' '))

f="a.txt"
s="*.cn"
t="FFF空格FFF"
#方法1 字符替换
def f1(f,s,t):
    a=open(f,"r")
    txt=a.read()
    a=open(f,"w")
    txt=txt.replace(s,t)
    a.write(txt)
    a.close()
    print("f1:\n",txt)
#f1(f,s,t)

#方法2 正则替换
import re
s="\*\.cn"
def f2(f,s,t):
    a=open(f,"r")
    txt=a.read()
    a=open(f,"w")
    s=re.compile(s)
    txt=re.sub(s,t,txt)
    a.write(txt)
    a.close()
    print("\r\nf2:",txt)
#f2(f,s,t)

#方法3 split切分再join
txt=open(f,"r").read()
txt=txt.split("*.cn")
txt=t.join(txt)
print(txt)

'''
output:

城里人真会玩

Local $str = "23423回来日3咽螺距3是啊kljsdfsjf;ajs;fdjsafjsklfjklsdjfklsjfklj3kl*.cnkljdsflkklfsj*.cnkljdfkjdfjdlkjkl*com*YcnX.cn"
$str = StringReplace($str,"*.cn", " ")
