 <p>When you write useful scripts, put them in a directory and add that directory to your PATH.  I use <code>~/Dropbox/bin</code> and I have a script named <code>e</code> in that directory for editing files.  So <code>e test.sh</code> lets me edit <code>test.sh</code> from the command line.</p>
+
+<p>Note that Bash will only look in your PATH for scripts unless you give an explicit path to the script.</p>
+
+<code block>
+~/learn $ # edit test.sh
+~/learn $ cat test.sh 
+echo this is a shell script
+~/learn $ test.sh
+-bash: test.sh: command not found
+~/learn $ ./test.sh 
+this is a shell script
+~/learn $ 
+</code>
+
+<p>Calling <code>test.sh</code> by itself fails because it isn't in the PATH.  But <code>./test.sh</code> works because it is an explicit path.</p>
