Sorting a device list

[Peter Steele]

I ended up using

ls /dev/ad*|sort -g -k1.8

Not quite as generic as I wanted but it works...

you can try to delete the /dev/ad10 entry with sed and then just append it to the end manually using the
printf(1) utility like so:

# ls /dev/ad* | sed s/"\/dev\/ad10"// | grep "/dev/ad" && printf "/dev/ad10\n"

Does that help?

I had tried that. It doesn't work:

# ls -d1 /dev/ad* | sort -n
/dev/ad10
/dev/ad4
/dev/ad6
/dev/ad8
I want the ad10 to appear last...

Just use `sort -n':

   ls -d1 /dev/ad* | sort -n

It should work fine even when there are non-numeric prefix strings.
