I would like to sort the temp.txt contains like the following.

1_r105.png
1_r15.png
1_r150.png
1_r155.png
1_r160.png

Anybody can help me?
I used sort -n temp.txt sort.txt
But it is not working correctly.
I am working under cygwin in WindowsXP.
Lol, so now I'm not an expert on linux utilities but I enjoy tinkering with it now and then... This is one way to solve _this_ problem, somehow I thought it would be possible to use the -k flag for start of key value for sort (btw this is not a c question as such I think)...
but this did the trick (for this case) sed -e 's/1_r//' temp.txt | sort -n | xargs --replace=num echo l_rnum > output.txt
I am working under cygwin in WindowsXP.
I hope [s]he has sed. :)
