How to execute bash script in same shell

Question

I have a bash script which is calling three different commands and that execution must happen in one shell. I got it by adding && after each command like as follows-

CMD1 && CMD2 && CMD3

Now what i need is- lets say i open a terminal on my MAC machine, all commands should run in open shell not in new sub-shell.

As a side note- CMD1 is actually a source command to my project directory which is a bash script which sets all the environment variable for running server.

thanks @KyleStrand actually my CMD1 is itself a source command. That is why i am looking for running bash script in current shell. Because CMD2 and CMD3 depends on environment set by CMD1. — Sam

...then your question is unclear; commands aren't intrinsically "source commands". Do you mean that your script actually looks like . CMD1 && CMD2 && CMD3? If so, your question should say that. — Kyle Strand

Please edit your question to clarify what your script looks like and what your requirements are. "CMD2 and CMD3 depends on environment set by CMD1" should be specified in the question itself, not in a comment. — Kyle Strand

First, you will need to save save the command in a scriptfile, for example Myscript.sh.

Second, you can execute the script file to run your commands simultaneously using

. ./Myscript.sh

The first . stands for current shell and the second . for current directory.

Would be nice to explain also that it's actually sourcing the bash script

What is the difference between running a script with source and the answer mentioned above ?
