+====== SED - New line ======
+Neither **\s*** (as I would use in javascript and php) nor **\s\{3,\}** works.
+Note too that **\n** is not recognized as a new line.  To get a new line **\'$'\n** must be used.
+To modify the .profile file.
+<code sed>
+#sed -i .bak  's/^\(export[ ]*JAVA_HOME.*\)/#&\'$'\nexport\ JAVA_HOME=\/Users\/${USER}\/\.java_jdk_6\/soylatte16-i386-1\.0\.3/' ~/.profile
+#sed -i .bak  's/^\(export[ ]*JAVA_HOME.*\)/&\'$'\nexport\ PATH=${JAVA_HOME}\/bin:$PATH/' ~/.profile
+</code>
+The two lines above did what I wanted but the second line did a backup of the modified ~/.profile.  So I came up with the next solution.
+<code sed>
+sed -i .bak  's/^\(export[ ]*JAVA_HOME.*\)/#&\
+\export\ JAVA_HOME=\/Users\/${USER}\/\.java_jdk_6\/soylatte16-i386-1\.0\.3\
+\export\ PATH=${JAVA_HOME}\/bin:$PATH/' ~/.profile
+</code>
+The new line is achieved by ending a regex with \ and continuing it with \ on the next line. If there are white spaces in front of \ they will also appear in ~/.profile.
