I’m trying to grep against a windows file under cygwin or linux, to find all MySQL statements between a table lock and table unlock in a mysql log.
I can use awk, but I need the line numbers from the original file
I don’t see why -Pzo isn’t working in cygwin
Effectively I’m looking for is a way to locate statements which are prevented from obtaining a lock (where the main query is interrupted)
If I can at least get sensible results from grep then I can then search the results to find entries where something has interrupted the query.
2302221 Query LOCK TABLES browse WRITE, browse_being_allocated WRITE
2302221 Query SELECT id,startAtom,finishAtom FROM browse_being_allocated WHERE poolID = 31543 AND rushID = '32ca680dd0d84f9b9b2945e2186c09ff' AND format = 516 AND startAtom <= 1182716 AND finishAtom > 1182716
2302221 Query INSERT INTO browse (poolId,atom,skew,format,rushID,start,finish,databytes,srcPoolID,srcAtom,srcSkew,arrived) VALUES (31543,1182716,0,516,'32ca680dd0d84f9b9b2945e2186c09ff',274545,274588,315392,0,0,0,1)
2302221 Query UPDATE browse_being_allocated SET startAtom = 1182717 WHERE id = 26471948
2302221 Query UNLOCK TABLES
2522564 Query LOCK TABLES browse WRITE, browse_being_allocated WRITE
2522564 Query SELECT id,startAtom,finishAtom FROM browse_being_allocated WHERE poolID = 31543 AND rushID = '32ca680dd0d84f9b9b2945e2186c09ff' AND format = 516 AND startAtom <= 1182717 AND finishAtom > 1182717
2522564 Query INSERT INTO browse (poolId,atom,skew,format,rushID,start,finish,databytes,srcPoolID,srcAtom,srcSkew,arrived) VALUES (31543,1182717,0,516,'32ca680dd0d84f9b9b2945e2186c09ff',274588,274633,331776,0,0,0,1)
2522564 Query UPDATE browse_being_allocated SET startAtom = 1182718 WHERE id = 26471948
2522564 Query UNLOCK TABLES
The example above would be sensible, and below would represent the first part of a fault condition.
2334151 Change user user@dbsrv1 on db
2334151 Query SET NAMES utf8
2334151 Query SET character_set_results = NULL
2334151 Query LOCK TABLES browse WRITE, browse_being_allocated WRITE
2302201 Change user user@dbsrv1 on db
2302201 Query SET NAMES utf8
2302201 Query SET character_set_results = NULL
2302201 Query SELECT DISTINCT rushID FROM tags WHERE rushID NOT IN (SELECT DISTINCT rushID FROM essencefragments) GROUP BY rushID
151216 19:00:39 2566722 Quit
I’ve tried many different ways to get a multiline match, but I’ve simply not been able to get anything working. Ideally I’d get it going under cygwin, and I really need to keep the original line numbers so I can jump back to the original logs and tie it up.
Any thoughts? Cheers

Answer
awk should be able to do what you want. I think perl and sed probably would too for that matter.
Using the -E (extended regex) I believe is making your regex too greedy. As far as why your grep -P is not working, you’ll have to use grep –version and grep–help and do some research. Mine is working fine with GNU grep 2.22 on Ubuntu 16.04.
If I understand your question correctly (which I very well may not), you’re wanting everything between LOCK and UNLOCK strings. Would this be a viable solution?
awk 'BEGIN {ln=1; lck="n"; print "---"};
lck=="y" {print ln")",$0};
$3=="UNLOCK" {lck="n"; ln++; print "---"; next};
$3=="LOCK" && lck=="n" {print ln")",$0; lck="y";ln++; next};
{ln++};
' NEWSJBHQDB12A.log > NEWSJBHQDB12A_filtered.txt;
It should keep track and display the line numbers (var ln) for you to easily reference against your original log file. With the use of the “lck” variable as an on/off switch, it will begin printing when it finds “LOCK” and stop printing when it finds an “UNLOCK.”
