multi-line variable in tcsh

Question

I want to have variable in tcsh to hold the usage info of my script, so in my script, whenever I write echo $usage, it will print

my_script
  -h : -help
  -         


        

Answer 1

Using '' stops variables being evaluated, not an issue in your case but can be in other situations. To make it a little more readable and allowing the string to be spread over multiple lines I use the following:

#!/bin/tcsh

set help =      "my_script   \n" 
set help = "$help  -h : -help\n"
set help = "$help  -b : do boo"

echo $help:q
