Hi,

Can someone help me with this small piece of code.

DIRNAME=$(dirname $0)
BASENAME=$(basename $0)
DATA="${DIRNAME}/${BASENAME}.data"
[ -r $DATA ] && . $DATA

whats is meant by [ -r $DATA ] && . $DATA here...

Regards,
Abhishek

If $DATA exists and is readable, source (read) the file $DATA and include its contents in the current shell script

Ok.....
so this is a condition but without an "if ... fi" block?

Thanks for the help friend.

Regards,
Abhi
