任何想法如何使用GNU sed,awk,cu或perl/python自动化...谢谢!

Answer 1

运用 sed

sed -n ':a;$!N;/--/!s/\n/|/g;ta;P' inputFile


$ sed -n ':a;$!N;/--/!s/\n/|/g;ta;P' temp

阐释:

• :a 创建标签a.
• $!如果不是最后一行; 做
• N 得到一个新的路线
• /--/!如果行与此正则表达式不匹配; 做
• /s/\n/|/g 用管子代替新线
• ta 如果替换成功,则返回标签
• P 打印线.

注:这里的区别是p,P,n和N.

• 该n命令将打印出当前模式空间并读入下一行输入.
• 该N命令不会打印出当前的模式空间.它读入下一行,但将新行字符与输入行本身一起附加到模式空间.
• 该p命令打印整个模式空间.
• 该P命令仅打印模式空间的第一部分,直到NEWLINE字符.
