awk Script

I am trying a script where i awk the output text file to a csv file

Attached are the input file , I am a newbie at bash scripting

Input Text file
Code:


awk '
/NE name:/ {
        n = $4
}		
/System Name:/ {
        r = $4
}		
/System Name: / {
        p = $3  $4  $5  $6		
		print n , r , p


		
}' OFS=, /cygdrive/c/output/LLDP/output.txt >>$i



Desired CSV output


Code:
AA2M3A 	172.17.168.226	 ER_3898_1_FON	Huawei RTN 980
AA2M3A        172.17.168.226	ER_3898_1_FON	        Huawei RTN 980
ABHM7a 	172.17.167.2	         HCX16.01          	        Huawei Versatile Routing Platform Software
ABHM7a 	172.17.167.2	         HCX16.02	                Huawei Versatile Routing Platform Software

Hi
Code:
enca output.txt
7bit ASCII characters
  Mixed line terminators

Does that bother you?

Your spec seems a bit incomplete, pls add more details:
- how to select / reject the devices (e.g. 172.17.168.227 is missing in your desired output)?
- how to fill items not yet found when encountering the print trigger ("System Name:")?
- why not use "System Description" as the print trigger?
- why <TAB> chars in your desired output, not the commas set as OFS in your script?


Is it possible to get a somewhat more structured data file to analyse?


With what we have got now, how far would this get you:
Code:
awk '
                {sub ("\r+$", _)
                }
/spawn/         {sub (/^.*@/, _)
                 IP = $0
                 NENM = DESC = ""
                }               
/NE name:/      {NENM = $4
                }
/System Name: / {sub (/^System Name: /, _)
                 SYNM = $0
                }
/System Desc/   {getline
                 sub ("\r+$", _)
                 print NENM, IP, SYNM, $0
                }
' OFS=, /tmp/output.txt
AA2M3A,172.17.168.226,ER_3898_1_FON,Huawei RTN 980

Thanks alot this worked perfectly but i have one issue you can see in my output the script is skipping the first result for System Capabilities: and IP:

Code:
awk '
                {sub ("\r+$", _)
                }
/spawn/         {sub (/^.*@/, _)
                 IP = $0
                 NENM = DESC = ""
                }               
/NE name:/      {NENM = $4
                }
/System Capabilities: / {sub (/^System Capabilities: /, _)
                 SYCP = $0
                }
/System Name: / {sub (/^System Name: /, _)
                 SYNM = $0
                }
/Local Intf: / {sub (/^Local Intf: /, _)
                 LCINF = $0
                }
/IP: / {sub (/^IP:  /, _)
                 MGIP = $2
                }
/Port id: / {sub (/^Port id: /, _)
                 RMPR = $0
                }
/Chassis id: / {sub (/^Chassis id: /, _)
                 CHID = $0
                }					
/System Desc/   {getline
                 sub ("\r+$", _)
                 print NENM, IP, SYCP, LCINF, MGIP, SYNM, RMPR, CHID, $0awk '
                {sub ("\r+$", _)
                }
/spawn/         {sub (/^.*@/, _)
                 IP = $0
                 NENM = DESC = ""
                }               
/NE name:/      {NENM = $4
                }
/System Capabilities: / {sub (/^System Capabilities: /, _)
                 SYCP = $0
                }
/System Name: / {sub (/^System Name: /, _)
                 SYNM = $0
                }
/Local Intf: / {sub (/^Local Intf: /, _)
                 LCINF = $0
                }
/IP: / {sub (/^IP:  /, _)
                 MGIP = $2
                }
/Port id: / {sub (/^Port id: /, _)
                 RMPR = $0
                }
/Chassis id: / {sub (/^Chassis id: /, _)
                 CHID = $0
                }					
/System Desc/   {getline
                 sub ("\r+$", _)
                 print NENM, IP, SYCP, LCINF, MGIP, SYNM, RMPR, CHID, $0


Output

Code:
AA2M3A.SNFN,172.17.168.226, ,Gi0/2/1,ER_3898_1_FON,GigabitEthernet 22/255/1,80b5.7543.cbcb,Huawei RTN 980

If I do this :
Code:
grep -E 'System Capabilities: |System Desc' output.txt

Then I get:
Code:
System Description: 
System Capabilities: B
System Description: 
System Capabilities: B
System Description: 
System Capabilities: B&R
System Description: 
System Capabilities: B&R

Which means that the first "System Description" is before "System Capabilities" , so the first time SYCP is unset when the first line is printed. So the order appears to be wrong.. You would need to pick a point in the file, where you can be sure that all variables have been read.

Also it is best to clear all variables after printing.

BTW. You script appears to be twice in there and a bit mangled...

@adgjmp: Your adapted script seems to target requirements not covered by your first spec. Be aware that it's best to prepare a decent, detailed spec covering the entire problem in order to avoid waste of resources and efforts.

Sorry for that actually after the script was working i was targeting a bigger output from the file, Like more details it can pull, It will be really helpful if i could get a solution for this, As i tried and was not able to figure out whats wrong.
