Consider the command:
scp my-machine:/home/user/a-folder/[massif,callgrind]* .
Where my intent is to copy only the files from my-machine:/home/user/a-folder/ that start with massif or callgrind keywords. As of right now, the substitution of [massif,callgrind] is also considering the empty string, thus copying any file in the folder because of the *.
What do I have to change to make it work correctly?

It sounds like you want curly-brackets there:
scp my-machine:/home/user/a-folder/massif,callgrind* .
Otherwise you're matching on single characters, rather than the two complete strings.

Aha! That is it. In fact it was accepting anything that would start with these letters plus the comma. Thank you!
