嘿嘿，按照你的意思，但是似乎我这里出错，我是在ＷＩＮＤＯＷＳ环境下运行perl的，错误信息："Bad name after F' at C:\Documents and Settings....."

WINDOWS上'要换成"

perl -F"=" -lane "print $F[1] if /^aaa/" urfile

用shell

1. 
   
2. cut -d "=" -f2 yourfile
   

复制代码

perl -F"=" -lane "print $F[1] if /^aaa/" urfile

似乎"F"这个东西有问题.错误信息:

String found where operator expected at C:\Documents and Settings\lyu\Desktop\Bb
\old.pl line 22, near "F"=""
String found where operator expected at C:\Documents and Settings\lyu\Desktop\Bb
\old.pl line 22, near "lane "print $F[1] if /^aaa/""
        (Do you need to predeclare lane?)
String found where operator expected at C:\Documents and Settings\lyu\Desktop\Bb
\old.pl line 22, near ""print $F[1] if /^aaa/" "C:\\Documents and Settings\\lyu\

        (Missing operator before  "C:\\Documents and Settings\\lyu\\Desktop\\Bb\
\1111.txt"?)

perl -F"\=" -lane "print $F[1] if /^aaa/" urfile

写在脚本里了？

我这个是直接在 “命令行” 执行的啊！

perl -F"\=" -lane "print $F[1] if /^aaa/" urfile

perl -F"\=" -lane "print $F[1] if /^aaa/" 'C:\\Bb\\1111.txt'

我程序如上.还是有问题.

joewish

'C:\\Bb\\1111.txt'???

直接写成 "c:/xxxx/xxxx/xxxx"
或者  "c:\\xxxx\\xxxx\\xxxx"

":" 有没有\ 我忘了  - - 汗  学到没忘的多

命令行OK,要是放到脚本里面,应该如何改变一下呢?
