I have an input file like
Code:
RMS_RPT_PERIOD_DIM,Table,NYTD_SLS_DM,GPS_SLS_DM1,NYTD_SLS_GPS_INT,RMS_DM,byreddys,7/31/2009,byreddys,7/31/2009,Y,//depot/eqr/salesgps/trunk/src/db/table,TBL_GPS_CONTACT_DETAILS.sql,1.1,,lakshmi,sql,y
GPS_SLS_DM1,Table,NYTD_SLS_GPS,GPS_SLS_DM1,NYTD_SLS_GPS_INT,GPS_SLS_DM_IN,byreddys,8/3/2009,byreddys,8/3/2009,Y,//depot/eqr/salesgps/trunk/src/db/schema,GPS_SLS_DM,1.1,,lakshmi,sql,yNow i want to read these records in a while loop one after another
My code is liek this.
Code:
Object_Name=0
OBJECT_TYPE=1
Source_DB_Name=2
Source_Schema=3
Target_DB_Name=4
Target_Schema=5
DATA_LOAD=10
Perforce_Directory_Name=11
Perforce_Script_Name=12
DB_TYPE_IDX=15
PROCESS_IDX=16
while read line
do
# tokenize the string by ",".
var=(`echo $line | tr ',' ' '`)
if [ "${var[$PROCESS_IDX]}" == "y" ]; then
log_it "entered to process record ${num}"
It works fine. But when i am declaring these values in a seperate file like
a.prop
Object_Name=0
OBJECT_TYPE=1
Source_DB_Name=2
Source_Schema=3
Target_DB_Name=4
Target_Schema=5
DATA_LOAD=10
Perforce_Directory_Name=11
Perforce_Script_Name=12
DB_TYPE_IDX=15
PROCESS_IDX=16
and my code now is
#!/bin/ksh
# Set up the environment
. a.prop
....
while read line
do
# tokenize the string by ",".
var=(`echo $line | tr ',' ' '`)
echo $PROCESS_IDX
if [ "${var[$PROCESS_IDX]}" == "y" ]; then
log_it "entered to process record ${num}"echo $PROCESS_IDX is printing 16
but
if [ "${var[$PROCESS_IDX]}" == "y" ]; is failing it says : arithmetic syntax error 16
Please help me to resolve this issue.

escape
escape(1) Mail Avenger 0.8.3 escape(1)
NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`
SEE ALSO

The Mail Avenger home page: <http://www.mailavenger.org/>.
BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
