Full Discussion: Sequential numbering from 1 to ten
Top Forums Shell Programming and Scripting Sequential numbering from 1 to ten Post 302890021 by Chubler_XL on Monday 24th of February 2014 09:57:50 PM

How about this:

Code:
#!/bin/bash

max_num() {
   max=0
   for file in [0-9][0-9][0-9]_*
   do
      [ ! -f "$file" ] && return
      num=${file%%_*}
      [ $num -gt $max ] && max=$num
   done
}

cd /path/to/folder
while true
do
    max_num
    for file in *
    do
       [[ ! -f $file || "$file" = [0-9][0-9][0-9]_* ]] && continue
       ((max++))
       printf -v new_name "%03d_%s" $max "$file"
       mv "$file" "$new_name"
    done
    sleep 1
done

Sorry just re-read your requirements and I think this is probably closer to what you asked for:

Code:
#!/bin/bash

mv_down() {
   for ((i=9; i ; i--)) {
       [ -f "${i}_$1" ] && mv -f "${i}_$1" "$((i+1))_$1"
   }
   mv "$1" "1_$1"
}

cd folder
while true
do
    for file in *
    do
       [[ ! -f "$file" || "$file" = [1-9]_* || "$file" = 10_* ]] && continue
       mv_down "$file"
    done
    sleep 1
done
