[NTLUG:Discuss] Script question

[MadHat]

try something like this using awk

for x do
   n=`echo $x | awk -F . '{ $3++ };  { print $1"."$2"."$3 }'`
   echo "mv -f $x $n"
done


I made this a shell script called 'rename' and run
$ rename /var/log/filename*
the echo is just to show what is going on, once verified, it is just 'mv -f 
...'.  If you are already in a loop in a script, just use the awk part.  I 
am sure there are more elegant ways of doing this, but this works.
