Equivelant of a Wildcard

`ls`
This is exactly the same as a wildcard - good for times when wildcards are disabled and when you want have a wildcard of a directory that is not your current ({`ls /path/to/dir`}). Does not work on older versions of Bash though.

are the {} necessary?

if you use backticks often, especially in scripts, it's a good idea to override possible aliases...

According to the bash documentation (for the current version 4.0) aliases are only expanded for "simple commands" http://www.gnu.org/software/bash/manual/bashref.html#Aliases . In my shell, ls is aliased to "ls --color=auto" but if I do echo {`ls`} I don't get any color I just get the filenames in curly braces. I think you may be missing files at the beginning and end of the list because if you do: mkdir testdir; cd testdir touch file{1,2,3,4} ls {`ls`} then the result is ls: cannot access {file1: No such file or directory ls: cannot access file4}: No such file or directory file2 file3 so I think you are missing files with with curly braces and should leave them off.
