Question script executing . ./.script.sh

what is the difference between executing the script .script.sh and . ./script.sh.

Example : . ./.bash_profile


And also can any one tel me what do source command do?
# 2  
.script.sh

would try and find a program called ".script.sh" on the path and run them in a child process.

. script.sh

would basically interpret the script.sh commands inline

./script.sh

would try and find a program called "script.sh" in the current directory and run them in a child process.

source is an alias for .

Question

So can i run . ./.bash_profile from any of the location? Or do I need to be in the same directory?
