- To group several strings together as one argument it is necessary
to use double quotes:
"
- For example:
$ v=Hello World
$ echo $v
Hello
$ v="Hello World"
$ echo $v
Hello World
- NB: Variable substitutions are done inside double quotes but wildmasks are not expanded:
e.g. echo "*" just prints a *
but echo "$v" is the same as echo $v
