Find matched pattern and print all based on certain conditions

Hi,

I am trying to extract data based on certain conditions. My sample input file as below:-

Code:
lnc-2:1	OnePiece	tra_law	500	688	1	.	.	g_id "R792.8417"# tra_law_id "R792.8417.1"# g_line "2.711647"# KM "8.723820"#
lnc-2:1	OnePiece	room	500	510	1	.	.	g_id "R792.8417"# tra_law_id "R792.8417.1"# room_number "1"# g_line "2.711647"#
lnc-2:1	OnePiece	room	540	588	1	.	.	g_id "R792.8417"# tra_law_id "R792.8417.1"# room_number "2"# g_line "2.711647"#
lnc-2:1	OnePiece	room	620	650	1	.	.	g_id "R792.8417"# tra_law_id "R792.8417.1"# room_number "3"# g_line "2.711647"#
lnc-2:1	OnePiece	room	660	688	1	.	.	g_id "R792.8417"# tra_law_id "R792.8417.1"# room_number "4"# g_line "2.711647"#
lnc-1:3	OnePiece	tra_law	1	3601	1	.	.	g_id "R792.8416"# tra_law_id "R792.8416.1"# g_line "36.370155"# KM "117.008842"#

lnc-1:3	OnePiece	room	1020	3001	1	.	.	g_id "R792.8416"# tra_law_id "R792.8416.1"# room_number "2"# g_line "36.370155"#
lnc-1:3	OnePiece	room	3400	3601	1	.	.	g_id "R792.8416"# tra_law_id "R792.8416.1"# room_number "3"# g_line "36.370155"#
lnc-9:1	OnePiece	tra_law	1743	2314	1	.	.	g_id "R792.8419"# tra_law_id "R792.8419.1"# g_line "27.213287"# KM "87.549683"#
lnc-9:1	OnePiece	room	1743	2314	1	.	.	g_id "R792.8419"# tra_law_id "R792.8419.1"# room_number "1"# g_line "27.213287"#
lnc-16:4	OnePiece	tra_law	25408	63025	1	-	.	g_id "R792.8420"# tra_law_id "R792.8420.1"# g_line "357.721802"# KM "1150.850586"#
lnc-16:4	OnePiece	room	25408	25528	1	-	.	g_id "R792.8420"# tra_law_id "R792.8420.1"# room_number "1"# g_line "765.276733"#
lnc-16:4	OnePiece	room	62888	63025	1	-	.	g_id "R792.8420"# tra_law_id "R792.8420.1"# room_number "2"# g_line "0.372920"#

I want to get an output where when all conditions are met, it should print every lines with the same name in $1. The conditions as follows:-

1) "tra_law" is found in $3 && the results of $5 - $4 (of tra_law) is > 200. It should print all the following lines associated with it.
2) Then, it should check for the room number in last column, where only room_number with min of 3 counts will be taken into consideration.

The output should be like below:-

Code:
lnc-1:3	OnePiece	tra_law	1	3601	1	.	.	g_id "R792.8416"# tra_law_id "R792.8416.1"# g_line "36.370155"# KM "117.008842"#
lnc-1:3	OnePiece	room	1	601	1	.	.	g_id "R792.8416"# tra_law_id "R792.8416.1"# room_number "1"# g_line "36.370155"#
lnc-1:3	OnePiece	room	1020	3001	1	.	.	g_id "R792.8416"# tra_law_id "R792.8416.1"# room_number "2"# g_line "36.370155"#
lnc-1:3	OnePiece	room	3400	3601	1	.	.	g_id "R792.8416"# tra_law_id "R792.8416.1"# room_number "3"# g_line "36.370155"#

as you can see, only lnc-1:3 met the conditions. for lnc-2:1, the tra_law value is less than 200 (688 - 500 = 180), therefore, it is omitted. As for lnc-9:1 and lnc-16:4, though the tra_law value > 200, both are omitted too as the room_number counts are less than 3.

I tried to use awk to work on it. My codes as below:-

Code:
awk -F"\t" 'NR>2 {$20=$5-$4; if ($20>200 && $3 ~/tra_law/) print $0}' inputfile | awk '{NF--NF};1' > outputfile

I got the results of the conditions no 1. But, it did not print the following lines associated to it. Also, I do not know how to check for condition no 2. I would prefer for the condition no 2 to be put in separate awk command as I might need to use them separately in different situation. Tried it many times but failed. Appreciate your kind help. Thanks.

Help me out: what does {NF--NF} do in your second awk script do? An uncommon construct, at least to me...

For your problem, how about
Code:
awk -F"\t" '
NR > 2           &&
($5-$4) > 200    &&
$3 ~ /tra_law/  {if (CNT > 3) print substr (OUT, 2)
                 SRC = $1
                 OUT = ""
                 CNT = 0
                }
$1 == SRC       {OUT = OUT ORS $0 
                 CNT ++
                }
END             {if (CNT > 3) print substr (OUT, 2)
                }

Hi RudyC,

Thanks so much...your codes work great on my real data.

If you notice, I created $20 to put in the total of $5 - $4. I need to remove $20 (last column) from being printed out in the final output. Therefore, i used {NF--NF} for that purpose. Smilie It was just my silly way I guess.
# 4  
Well, yes, I noticed the necessary removal of $20. So NF-- would remove it (if it is the last field). What is the trailing NF for?


And, why $20 when your entire file has only 9 fields per line consistently?
And - as I see now - why the NR>2 condition? You normally use this to eliminate e.g. headers. But your file seems to have valid data in lines 1 and 2?

--> I have found ways of removing the last column here in this link:
text processing - How to delete the last column of a file in Linux - Unix & Linux Stack Exchange

Code:
awk 'NF{NF-=1};1' <in >out
or:

awk 'NF{NF--};1' <in >out
or:

awk 'NF{--NF};1' <in >out
Although this looks like voodoo, it works. There are three parts to each of these awk commands.

The first is NF, which is a precondition for the second part. NF is a variable containing the number of fields in a line. In AWK, things are true if they're not 0 or empty string "". Hence, the second part (where NF is decremented) only happens if NF is not 0.

The second part (either NF-=1 NF-- or --NF) is just subtracting one from the NF variable. This prevent the last field from being printed, because when you change a field (removing the last field in this case), awk re-construct $0, concatenate all fields separated by space by default. $0 didn't contain the last field anymore.

The final part is 1. It's not magical, it's just used as a expression that means true. If an awk expression evaluates to true without any associated action, awk default action is print $0.

And, why $20 when your entire file has only 9 fields per line consistently?
-> My real data has more than that. The one that i put here just a sample. The real data quite long and messy Smilie

And - as I see now - why the NR>2 condition? You normally use this to eliminate e.g. headers. But your file seems to have valid data in lines 1 and 2?
-> I do have 2 lines header in my real data that need to be omitted. Smilie

Hi,

I noticed that the code did not work for the below condition.

Code:

I got the below output. By right, all the data above should be thrown out.

Tried to play around with the given codes but it didnt work. Need your kind help again. Thanks

Well, looks like any tra_law line should reset the counters, regardless of the $5 - $4 delta value. Try this small adaption.



Code:
awk -F"\t" '
NR > 2           &&
$3 ~ /tra_law/  {if ((CNT > 3) && (DELTA > 200)) print substr (OUT, 2)
                 DELTA = $5 - $4
                 SRC = $1
                 OUT = ""
                 CNT = 0
                }
$1 == SRC       {OUT = OUT ORS $0 
                 CNT ++
                }
END             {if  ((CNT > 3) && (DELTA > 200))  print substr (OUT, 2)
                }

Your new file seems to have multiple <TAB> chars as field separators?
