Hello, I have a log file that needs to be parsed. The logic is to find the word " Error at " (case insensitive) in the text file and once found read backwards to to find the first occurrence of string starting with word executing: (something like below) executing: @C:\parse_test\test\dir1\dir1.sql and once found delete or unlink the file at the path. In this case delete dir1.sql and not dir2.sql. The log file has the below contents 
 

connecting to Oracle with C:\Oracle\instantclient/sqlplus.
executing: @C:\parse_test\test\dir1\dir1.sql
alter tablexxxxxx add xxxxxxxxL VARCHAR2(3)
*
ERROR at line 1:
ORA-01430: column being added already exists in table


ERROR at line 37:
ORA-01430: column being added already exists in table

so far I have 

#!/usr/bin/perl
{local $/;$_=<>}
unlink $1 or warn "$1 $!" while /executing: \@(.*)(?ms:.*?ERROR at)/g;

Running this as test.pl C:\logfile\dir\log.txt It seems to be inconsistently working. Sometimes it deletes files that got successfully executed.
