trackingnum in the position 1-6 6 bytes
trackingnumsuffix in the position 8-9 2 bytes
effdate in the position 11-20
tstmpupdated in the position 22-57 26 bytes
I dont know how to use substring.
Basically I need to extract the trackingnum, trackingnumsuffix and tstmpupdated and pass those values to a query. If it is present in that table, then I need to store the output of query to a file.
I have tried by writing the shell script as follows.
Code:
====================
#! /bin/ksh
############################
# AFI Monitor Script
############################
. /db2/uszlad48/sqllib/db2profile
export mondir=/home/bmwdev1/script/krishna/arc
export monlog=$mondir/rcbl2_`date +%Y%m%d`.log
# connect to DB
db2 connect to r2pdev user bmwdevup using summer08
while read line
do
trackingnum=`expr substr $line 1 6`
trackingnumsuffix=`expr substr $line 8 9`
tstmpupdated=`expr substr $line 22 57`
#db2 "SELECT * FROM ZB_RCBL_ERROR_MSG_MIG WHERE TRACKING_NUM = $TRACKING_NUM AND TRACKING_NUM_SUFFIX = $TRACKING_NUM_SUFFIX AND TIMESTAMP_UPDATED = $TIMESTAMP_UPDATED WITH UR" >> new.log
done < "$monlog"
# disconnect from DB2
db2 terminate
exit 0
====================
The above shell script is not working. It throws error message.
Can anyone help me to fix this issue.

What is the error messsage?
Do you still get it after enclosing $line in quotes?
For sample I have given 3 records. But in production there will be n number of records.
So I am reading line by line in a loop.
The first field trackingnum will be in the position 1-6
The field trackingnumsuffix will be in the position 8-9
the tstmpupdated will be in the position 22-57
Code:
while read line
do
trackingnum=`expr substr $line 1 6`
trackingnumsuffix=`expr substr $line 8 9`
tstmpupdated=`expr substr $line 22 57`
db2 "SELECT * FROM ZB_RCBL_ERROR_MSG_MIG WHERE TRACKING_NUM = $TRACKING_NUM AND TRACKING_NUM_SUFFIX = $TRACKING_NUM_SUFFIX AND TIMESTAMP_UPDATED = $TIMESTAMP_UPDATED WITH UR" >> new.log
done < "rcbl2_`date +%Y%m%d`.log"
try to echo $line inside while loop and check whether you are getting the required line..
and you have to use double quotes if $line has space
because i am getting no errors

i am a new user of C-shell script.
I want to know can i create a substring in a string.
That means when i got a variable $input = "it is number 2"
I want to get the "2" to be another variable.
Can i do that in C-shell and how to ?
Thank you so much
