title: chop string(arguments passed by user)
body: <p>suppose the user passed 5 arguments(<code>$1</code> <code>$2</code> <code>$3</code> <code>$4</code> <code>$5</code>), how do I cut off the first two arguments(<code>$1</code> <code>$2</code>) and I only want the last 3 arguments</p>
  <p><code>awk '{print $3,$4,$5} &lt; $@' </code>
  what if I don't know how many arguments passed but I do not want the first two arguments</p>
  <p>I can not use shift since I also need info from $2, what should I do then?</p>
  <p>I ran into this problem when tar files in bash script when the user might use regular expressions like <code>*.txt</code> and the shell will automatically convert that into <code>file1.txt</code> <code>file2.txt</code> (suppose there are only two <code>.txt</code> files)</p>
