how to read delimited text into array
I am trying to parse a string using delimited char into array.
BNAME=B10,B20,B30
B10.Q=X
B20.Q=Y
B30.Q=Z

I need to parsethe BNAME into array, then i will loop through array to execute command using these variables. like:
for i in $array
do
qload array[i] array[i].Q # execute command: qload B10 X
done

Hi, adars1:

Code:
B10.Q

A dot is not a valid character in a shell variable.

Perhaps something like this will work for you:
Code:
#!/bin/sh

BNAME='B10 B20 B30'
B10=X
B20=Y
B30=Z

set -- $BNAME
for name in "$@"; do
    eval echo qload \$name \$$name
done

Running it gives:
Code:
$ ./adars1.sh 
qload B10 X
qload B20 Y
qload B30 Z

When you're ready to try it for real, remove the "echo" following the eval command.

Regards,
Alister

# queue name
DONEBR10=X
DONEBR20=Y

set -- $BR_NAME
for name in "$@";
do
eval echo \$name \$$name
echo "---ddddd--------------------------"
done

-- I got follwing output
DONEBR10 DONEBR20 X DONEBR20
