What are the bash wildcards? (e.g *,?..)

That’s fair… it’s all the memory you’ll ever need… or so he says.
Good luck.

There are quite a few options for wildcards in Bash. I’m not sure how comprehensive this list is, but it’s at least a starting point:
- (asterisk) zero or more characters
? (question mark) one character
[abcde] - any one of the character from the contents of square brackets
[a-e] - any one character in the range defined either side of the dash within square brackets
!abcde] or !a-e] modifies the two previous examples with “not”
{suse,linux} any one string from the options listed in curly brackets
Strictly speaking that last one {suse,linux} isn’t a wildcard but brace expansion. What is the difference? Brace expansion works even if there is no match. Say you have file1 and file3 in a directory.
echo file[1-3]
will get you file1 file3, but
echo file{1,2,3}
will get you file1 file2 file3
You can read all about brace expansion in the man page.
