Hi All,
Could anybody please tell me the exact difference between running a shell script with . and running it with source command?
For example, the difference between
. /opt/bea/wlserver_10.3/common/bin/commEnv.sh

and

source /opt/bea/wlserver_10.3/common/bin/commEnv.sh


Thanks in advance!

Nothing. THere's no difference. "." is just a shortcut for typing "source"

It's actually the other way around :-) "." has been there for a long time, and "source" is a newer longer bash-specific way to write it.
