numerically sorted filenames
How do you sort filenames:
Code:
1 2 3 4 5 6 7 8 9 10 12 13 14 15 16 17 18 19 20 21

as:
Code:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21

instead of:
Code:
1
10
11
12
13
14
15
16
17
18
19
2
20
21
3
4
5
6
7
8
9

Thanks,
Kenny.

actually I have a constant word at the beginning of each file name.
example: filename_
ls | sort -n is not working on my list of files.
I still get:
Code:
filename_1
filename_10

etc
instead of:
Code:
filename_1
filename_2

etc.

NOTE: I am using Unix For Microsoft Windows commands.

Do you have Perl there?
Code:
ls | perl -F"\n" -la0ne '$,="\n";print sort {(split /_/,$a)[1]<=>(split /_/,$b)[1]} @F'

Code:
ls | nawk -F_ '{print $NF,$0}' | sort -k 1,1n | cut -d ' ' -f2-

You can still make it simpler by:
Code:
ls filename*  | sort -t'_' -k 2,2n

If you are using gnu ls, check out the "-v" option.
