This will increment the second field in the file for each file in the directory named *.ext.  

The last digit before dot will increment by 1; yet if it is 9 it should become 0.

[Caveat - untested...(use carefully)]:

ls *.ext |
awk -F"." '{s=substr($2,length($2))
s++;s=s==10?0:s
printf("mv %s %s%s.%s\n", $0, substr($2,1,length($2)-1), s, $3)}
' | sh

assuming you're just trimming off ccna, pc1, and ext

for i in $( ls )
do
mv $i $( echo $i | awk -F. '{ print $3 }' )
done

That would move them to pod# names.

Can someone suggest a way to rename a directory of files like this:



ccna.pod1.pc1.ext is renamed to ccna.pod2.pc1.ext

ccna.pod2.pc1.ext is renamed to ccna.pod3.pc1.ext



and so on.



(Aside: Hans, if I were able to take your scripting class I won't be asking this now. :-)
