## Example
### Manually
(edit ~/.bash_profile and append)
```
# Setting PATH for something
PATH="/new/dir/location/bin:${PATH}"
export PATH
```
### Terminal
```echo "export PATH=/new/dir/location/bin:$PATH" >> ~/.bash_profile```
___
### Then reload the profile
```source ~/.bash_profile```
**Note**
This reloads your bash profile in the current tab or session.
Either you enter this command on every tab or session, or restart Terminal.
