Scripts, cont'd

• A special variable called argv is defined inside a script (shell). It contains any arguments passed to the script (shell).

  • E.g. echo $argv [show all arguments]
  • echo $argv[2] [show the 2nd argument]
  • echo $#argv [show the number of args]

• You can do integer math within a script using @.

  • E.g. set x = 0; @ x = $x + 1; echo $x [good for loops!]
