Shell Programming and Scripting

Code:

#!/bin/csh 
  #
  # Time of day greeting 
  #
  # usage: greet [hour between 0-23]
  #
  if ($#argv == 0) then 
     set hour = ‘date +%H’
  else 
     set hour = $argv[1]
  endif
  #
  if ($hour < 12) then
     echo "Good Morning\!"
  else
     if ($hour < 18) then 
        echo "Good Afternoon\!"
     else 
        echo "Good Evening\!"
     endif
  endif
  #
  exit 0
  #

Why does the line set hour = ‘date +%H’ not work correctly?

I get an if: Expression syntax.

back-quotes, not single quotes.

Code:

set hour = `date +%H`

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.
