Top Forums Shell Programming and Scripting difference between echo and "" Post 302299439 by pludi on Friday 20th of March 2009 06:03:41 AM

Code:
$ var1='World!'
$ echo Hello $var1
Hello World!
$ echo Hello  $var1
Hello World!
$ echo "Hello $var1"
Hello World!
$ echo "Hello  $var1"
Hello  World!
$

The quotes tell the shell to interpret Hello and the substitution of var1 as one parameter (including the space(s)), instead of two parameters.
