title: How to get a command line parameter?
body: <p>suppose I am passing a command line parameters to my shell script as follows :</p>
  
  <p>ex 1 ) ./myshell_script a b c d e f</p>
  
  <p>ex 2 ) ./myshellscript f d e b c a</p>
  
  <p>My question is that , If I want to get the parameter "c" that is always after parameter  "b"  [ since the command line parameters may be provided in any order ] , How I can get the value that is always after parameter "b" ?</p>
