TO add a PATH to the existing one.
$ open -a TextEdit ~/.bash_profile export PATH=/path/to/the/folder:$PATH $ source ~/.bash_profile $ echo $PATH
Add the export line into the .bash_profile. Use the source command to update the path and use echo command to verify the path has been added.
Similarly, using vi/m, gedit or other text editor, add the export line into ~/.bash_profile the same way in Linux.
HINT: use \ in front of space to include them if they are part of the folder name.
