打印线使用grep命令

Question

匹配特定的字符串后，我想匹配的字符串

例如后打印的完整产品线，我有这样的输入： -

www.google.com/images 
    www.google.com/images/12 
    www.yahoo.com/images/12 
    www.bing.com/images/34 
    www.google.com/images/12 
    www.google.com/images/imagescols 

而且我想这样的输出： -

com/images    
com/images/12   
com/images/12   
com/images/34   
com/images/12   
com/images/imagescols 

请在unix中建议一种使用grep命令的方法。

Answer 1

您可以尝试下面的剪切命令。

cut -d. -f3 file 

OR

awk -F. '{print $NF}' file 

OR

grep -oE '[^.]*$' file 

例子：

$ cut -d. -f3 file 
com/images 
com/images/12 
com/images/12 
com/images/34 
com/images/12 
com/images/imagescols
