Rename filename with the next seq number

[shaokat]

Can you help me figure out how to write a awk / ksh or any unix script for this:

Eg: File to move: filename0001.out

Listing of files found at the location:

filename0001.out
filename0002.out
filename0003.out

Result:

filename0001.out
filename0002.out
filename0003.out
filename0004.out <-The new file moved in this location should get moved with the next avaiable sequence number.

TIA,

Try :
Pass the filename to change as a parameter to :

#!/bin/ksh
LOGFILE=`echo ${1}|cut -c1-8`
NUM=`echo ${1}|cut -c9-12`
while [ -f ${LOGFILE}${NUM} ]
do
((NUM = $NUM+1))
done
NUM=`echo $NUM | awk '{printf(&quot;%04d&quot;, $0);}'`
> ${LOGFILE}${NUM}.out
