In shell "pattern matching",
Quote:
[...] Matches any one of the enclosed characters. A pair of characters separated by a hyphen denotes a range expression; any character that falls between those two characters, inclusive, using the current locale's collating sequence and character set, is matched.
(cf man bash). So, [1-24] matches 1, 2, and 4. For your case, you might want to try "brace expansion" (cf man bash):
Code:
echo file{1..24}
file1 file2 file3 file4 file5 file6 file7 file8 file9 file10 ... file23 file24

so, in lieu of explicitly listing each and every file name, have the shell do it for you.
