Top Forums Shell Programming and Scripting Extract repeating and check for for certain error message Post 303025328 by Don Cragun on Tuesday 30th of October 2018 07:31:51 PM

If you're only processing completed log files, vgersh99's suggestion can be simplified a little bit:
Code:
awk '/ORA- error/' RS=  ORS='\n\n' myFile

If you are processing active log files and you want to be sure that the output only contains complete entries, you could still simplify it slightly:
Code:
awk '/Completed$/ && /ORA- error/' RS=  ORS='\n\n' myFile

If the trailing empty line at the end of the output produced by vgersh99's suggestion and the above two modifications bother you, you could also try:
Code:
awk '/ORA- error/{if(c++)print "";print}' RS= myFile

or:
Code:
awk '/Completed$/ && /ORA- error/{if(c++)print "";print}' RS= myFile

scanlogs

SCANLOGS(8)						      System Manager's Manual						       SCANLOGS(8)

NAME

       scanlogs - summarize INN log files.

SYNOPSIS

       scanlogs [ norotate ] [ nonn ]

DESCRIPTION

       Scanlogs  summarizes  the information recorded in the INN log files (see newslog(5)).  By default, it also rotates and cleans out the logs.
       It is normally invoked by the news.daily(8) script.

KEYWORDS

       The following keywords are accepted:

       norotate
	      Using this keyword disables the rotating and cleaning aspect of the log processing: the logs files are only scanned for  information
	      and no contents are altered.

       nonn   Normally the nn log file is scanned and rotated.	Using this keyword disables this function.

       If scanlogs is invoked more than once a day, the ``norotate'' keyword should be used to prevent premature log cleaning.
