Edit Question
Title
Body
When I needed to run a command multiple times with a different argument I used this approach (without understanding it fully): touch {a,b,c} Which is equivalent of: touch a touch b touch c I think the same could be accomplished with the following loop: for file in {a,b,c}; do touch $file; done However I've stumbled across a case where this does not work: pear channel-discover {"pear.phpunit.de","pear.symfony-project.com"} I have a few questions: What is the name of what is happening in the first example and what exactly is happening? Is it better to use this approach for simple things rather than for-in loops? Why the pear command is not working like that? Should the command script implement some techniques to handle such arguments or is it the shell responsible for that?
