Top Forums Shell Programming and Scripting Extracting Sysdate-1 ORA Errors - Can you help me in this UNIX Script? Post 302794755 by hanson44 on Tuesday 16th of April 2013 03:28:26 PM

I could not make the awk syntax work. The problem I ran into was using an awk command line variable inside a RE. Here was the closest I got:
Code:
$ cat log
Thu Apr 15 01:34:25 2013
Line 1 for April 15
Thu Apr 15 02:00:00 2013
Line 2 for April 15

Thu Apr 17 19:21:16 2013
Line 1 for April 17
Thu Apr 17 19:40:28 2013
Line 2 for April 17

Code:
a=`date '+%b %d' -d "yesterday"`
b=`date '+%b %d'`
awk '/$y/,/$t/ {print}' y="$a" t="$b" log

Maybe some other expert can provide an awk solution.

-----------------------------------------------

Here is a way to do this using sed:
Code:
a=`date '+%b %d' -d "yesterday"`
b=`date '+%b %d'`
echo a = $a, b = $b
sed -n "/$a/,/$b/ p" log | sed '$d'

Code:
$ ./temp.sh
a = Apr 15, b = Apr 16

AMANDA-SCRIPTS(7)						    Miscellanea 						 AMANDA-SCRIPTS(7)

NAME

       amanda-scripts - Configuring and using the Script API

DESCRIPTION

       The Script API is a flexible system for invoking user-supplied scripts at various points in the execution of Amanda. This manual page
       describes the operation and configuration of the API. For help writing Script API scripts, see http://wiki.zmanda.com/index.php/Script_API.

SCRIPTS

       This section lists the scripts included with Amanda, see the individual man page for instructions on using them. For complete How-To
       information, consult the Amanda wiki at http://wiki.zmanda.com.

       o   amzfs-snapshot(8), - create/destroy zfs snapshot.

       o   script-email(8), - send email.

       Script properties work just like application properties: they are insensitive to case, and - (dash) and _ (underscore) may be used
       interchangeably.

SCRIPTS OUTPUT PROPERTY

       A pre-dle-amcheck, pre-dle-estimate or pre-dle-backup executed on the client can output property on stdout that are sent to the
       application. If the output line matches "PROPERTY str1 str2", Amanda sets a property called "str1" by the value of "str2", that property is
       sent to the application.
