How to run 'cd' in shell script and stay there after script finishes?

I used 'change directory' in my shell script (bash)

#!/bin/bash
alias mycd='cd some_place'
mycd
pwd

pwd prints some_place correctly, but after the script finished my current working directory doesn't change.

Is it possible to change my path by script?

bash shell cd pwd

You need to source the file as:

. myfile.sh

or

source myfile.sh

Without sourcing the changes will happen in the sub-shell and not in the parent shell which is invoking the script. But when you source a file the lines in the file are executed as if they were typed at the command line.
