Equivelant of a Wildcard

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.

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
