I've a reference file, to take the parameter value. For example in the no of channel is 6 i have get the commands as written below. I need need a differenct logic to extract the commands.
Code:
NO_OF_CHANNEL=6
case ${NO_OF_CHANNEL} in
1) RMANCH1="allocate channel disk1 type disk;"
RMANCH2="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANCH3="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANCH4="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANCH5="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANCH6="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANRL1="release channel disk1;"
RMANRL2="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANRL3="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"

RMANRL6="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"

RMANCH2="allocate channel disk2 type disk;"
RMANCH3="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANCH4="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANCH5="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANCH6="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANRL1="release channel disk1;"
RMANRL2="release channel disk2;"
RMANRL3="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"

Can anyone give me different logic for this. Cz the No of channels have increased to 24 now and its difficult to right 24 cases as given above.
If anyone dont understand the question please heads up. I ll explain in detail. Kindly help me in any new logic.
#!/bin/sh
TOTAL_NO_OF_CHANNEL=24
#NO_OF_CHANNEL your input
for((i=0;i<TOTAL_NO_OF_CHANNEL;i++))
do
if [ $i -le $NO_OF_CHANNEL ]
then
RMANCH$i="allocate channel disk$i type disk;"
RMANRL$i="release channel disk$i;"
else
RMANCH$i="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
RMANRL$i="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
fi
done
NO_OF_CHANNEL=6
default="sql 'alter session set nls_date_format=\"DD-MON-YY HH24:MI:SS\"';"
for i in 1 2 3 4 5 6; do
if [ $i -le $NO_OF_CHANNEL ];
eval "RMANCH$i=\"allocate channel disk$i type disk;\""
eval "RMANRL$i=\"release channel disk$i;\""
else
eval "RMANCH$i=\"\$default\""
eval "RMANRL$i=\"\$default\""
fi
done
