awk解析文本文件的问题

Question

我刚刚开始学习如何使用awk解析和打印文本文件。

我已经开始用贝娄代码谁能帮我？

注意：报价在输出文件中是强制性的(见所需输出(

awk '/^IPDATA=/ && /A|B|C| '{print "ADD IP ="$0"n(n  Ref "$1",Type vlan="$2""n)n"}' file > file1 

注意：Ref是IPREF行的和，在这个例子中我们有三个：[2]&amp；[2] &amp；[1] 。

示例文本文件实际上是巨大的，但我已经概括了它：

IPDATA=A                IPID A            
IPDATA=A                IPREF   [2] =     
--- IPREF = VRID=A_1                      
--- IPREF = VRID=A_2                      

IPDATA=B                IPID B            
IPDATA=B                IPREF   [2] =     
--- IPREF = VRID=B_1                      
--- IPREF = VRID=B_2                      

IPDATA=C               IPID C             
IPDATA=C               IPREF    [1] =     
--- IPREF = VRID=C_1                      

我想得到以下结果：

"ADD IP=A "
( Ref  2
"Type vlan=VRID=A_1" 
"Type vlan=VRID=A_2" 
)
"ADD IP=B "          
( Ref  2              
"Type vlan=VRID=B_1" 
"Type vlan=VRID=B_2" 
)
"ADD IP=C "          
( Ref  1              
"Type vlan=VRID=C_1" 
)  

感谢

请您尝试以下内容，仅在GNUawk中使用所示示例编写和测试。

awk -v s1=""" '
/^IPDATA/ && /IPID .*/{
if(FNR>1){  print ")"  }
print s1 "ADD IP" s1 "="s1 $NF OFS s1
next
}
/^IPDATA.*IPREF.*[[0-9]+]/{
match($0,/[[^]]*/)
print "( Ref sum of IPREF " substr($0,RSTART+1,RLENGTH-1)
next
}
/^--- IPREF/{
print s1 "Type vlan="$NF s1
}
END{
print ")"
}
' Input_file

解释：添加以上详细解释。

awk -v s1=""" '                                               ##Starting awk program from here.
/^IPDATA/ && /IPID .*/{                                        ##Checking condition if line starts IPDATA and having IPID here.
if(FNR>1){  print ")"  }                                     ##Checking condition if FNR>1 then printing ) here.
print s1 "ADD IP" s1 "="s1 $NF OFS s1                        ##Printing s1 ADD IP s1 equal to s1 last field OFS and s1 here.
next                                                         ##next will skip all further statements from here.
}
/^IPDATA.*IPREF.*[[0-9]+]/{                                  ##Checking condition if line starts from IPDATA and having IPREF till [ digits ].
match($0,/[[^]]*/)                                          ##Using match to match from [ till ] in line.
print "( Ref sum of IPREF " substr($0,RSTART+1,RLENGTH-1)    ##printing string as per request and sub-string from RSTART+1 to till RLENGTH-1 here.
next
}
/^--- IPREF/{                                                  ##Checking conditon if line starts from --- IPREF then do following.
print s1 "Type vlan="$NF s1                                  ##Printing s1 string last field and s1 here.
}
END{                                                           ##Starting END block of this program from here.
print ")"                                                    ##Printing ) here.
}
' Input_file                                                   ##Mentioning Input_file name here.
