A shell variable named PATH contains a list of directories.  Any file that is 
executable under the directories listed PATH can be used without the need to 
explicitly specify its location. Generally, the most common place for a user 
to keep their own executables is in a folder called /home/<username>/bin.  To 
add this directory to your PATH, and a line like this:

export PATH=$PATH:$HOME/bin

to /home/<username>/.profile or /home/<username>/.bashrc (or the file for 
whatever shell you use).  Make sure you keep $PATH _before_ any other paths, 
so it will get precedence.  This will make sure that some malicious user 
cannot override the locations of any executables already on your system.

If you need to temporarily add some folder to your path, enter a line like 
this into your shell:

export PATH=$PATH:/some/place

%!PS: The syntax may vary, depending on what shell you use.  The examples here 
are for bash.
