Script to list Sequential files
I have sequential files like this. I'm trying to write a bash shell script to list all of them. These files are part of mysql to do database point in time recovery

Code:
bin.000001
.
.
.
bin.000999


I have something like this but it won't display bin.000010 and up. If anyone has a solution pls do let me know.
Code:
# find ~/ -name 'bin.00000[0-99]

Each character set [ ] matches one character
Code:
find ~/ -name 'bin.000[0-9][0-9][0-9]'

Thanks madelngermany,

I used find ~/ -name 'bin.0000[01-9][10-999]' and it worked.

Can you explain what is [01-9][10-999]?

A bit difficult to believe your pattern matched bin.000999 as it is for the last two digits only, one per square bracket pattern. First pattern will match 0 and 1-9, second 1, 0-9, 9, and 9 (some redundancy, i'd say).

Sorry, I made a mistake, my code did not work and i used your code it's working.

Pattern Matching

Any character that appears in a pattern, other than the special pattern characters described below, matches itself.
.
.
.
[...] 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.
So one [0-9] means one character from (the range) 0 through 9.
