+<h2>Use: The strings command returns each string of printable characters (ASCII)
+  in files. Its main uses are to determine the contents of and to extract text
+  from binary files (i.e., non-text files). </h2>
+
+<p>From the Shell manual: "find the printable strings in a object, or other binary,
+   file".<br>
+  Strings can be used to extract character information and string of a given lenght
+  from text file(s). When used without any options, strings displays all strings
+  that are at least four characters in length in the files whose names are
+  supplied as arguments (i.e., input data). Strings that are on separate lines
+  in the input files are shown on separate lines on the screen, and an attempt
+  is made to display all strings found on a single line in a file on a single
+  line on the screen (although there may be a carryover to subsequent lines in
+  the event that numerous strings are found on a single line). strings looks in
+  all sections of the object files except the (__TEXT,__text) section.</p>
+
+  <p>Basic syntax for this command is as follows:</p>
+
+   <pre>strings [options] file_name(s)</pre>
+
+   <pre>strings -n 2 file1 file2</pre>
+
+   <p>For example, the code above would display all strings in the files named
+     file1 and file2 that consist of at least two characters.</p>
+
+<h3> Flags <h3>
+  <ul>
+    <li><b>-n</b><br><br>
+    Specify the minimum string length, where the number argument  is
+    a positive decimal integer. The default shall be 4.</li>
+
+    <li><b>-</b><br><br>
+    This  option  causes strings to look for strings in all bytes of
+    the files (the default for non-object files).</li>
+
+    <li><b>--</b><br><br>
+    This option causes strings to treat all the following  arguments
+    as files.</li>
+
+    <li><b>-a</b><br><br>
+    This option causes strings to look for strings in  all  sections
+    of the object file (including the (__TEXT,__text) section.</li>
+  </ul>
