Problem while passing parameter to shell script which sends email-Ora Apps

Question

Hi,
I have a pl/sql package which will call a shell script program.The shell script program is written in order to send the invoice hold details of AP as a mail.The parameters to this program are passed in the pl/sql package.
The shell script program has
5 parameters namely
to - email
from - email
hold id - which is a number
hold name - varchar2( free text)
hold reason - varchar2( free text)
the shell script looks as below.
FROM_EMAIL=`echo $1|cut -f9 -d " "|sed 's/\"//g'`
echo "From email id is $FROM_EMAIL" -- From email
TO_EMAIL=`echo $1|cut -f10 -d " "|sed 's/\"//g'`
echo "To Email id is $TO_EMAIL" -- to email
PARAM0=`echo $1 | awk '{print $11}'|sed -e "s/\"//g"`
echo "Param0: $PARAM0" -- hold id
PARAM1=`echo "$1" | cut -d" " -f12-| sed -e "s/\" \"/\"^\"/g" | awk -F'^' '{print $1}'|sed -e "s/\"//g"`
echo "Param1: $PARAM1" -- hold name
PARAM2=`echo "$1" | cut -d" " -f13-| sed -e "s/\" \"/\"^\"/g" | awk -F'^' '{print $1}'|sed -e "s/\"//g"`
echo "Param2: $PARAM2" -- hold reason
the values that am passinf to this program are if suppose
from email ---- [email protected]
to email [email protected]
12345 ------ hold id
test hold name ------ hold name
test hold reason ------- hold reason
The output for the above parameters is as follows
from email ---- [email protected]
to email [email protected]
12345 ------ hold id
test hold name ------ hold name
hold name --------hold reason (a part of hold name parameter is displayed as hold reason.The reason being in param2 we used cut which is cutting from 13.
the problem here is since param1 being free text we cannot predict at what position the parameter ends.i mean there might be a single word or more than 2 words in that parameter seperated by space. the question here is ... is there anyway that we can specify dynamically from which location the param2 should fetch the value.
can we use some delimiter to identify the end of param1 and start of param2.If so... how can it be written in this scenario.
Thanks in Advance.

Answer 1

As I see, all parameters are merged into 1 at shell script.
Please do as follow:
1- Modify your shell script as followed:
echo "From email id is $1" -- From email
echo "To Email id is $2" -- to email
echo "Param0: $3" -- hold id
echo "Param1: $4" -- hold name
echo "Param2: $5" -- hold reason
2- rename your shell script file with .prog extension : CUSTOM_NAME.prog
3- perform the following command at custom file location:
ln -s $FND_TOP/bin/fndcpesr CUSTOM_NAME
This approach will seperate your parameters and then it will be more easier to manipulate them.
