If your script runs every hour, and the serialno resets at 00:00, then you can simply take the current hour as serialno.
The following is suitable for hourly crontab
Code:
ext=$(date +"%F").AAAAA$(date +"%H").BBBBBB.p

renamefile(){
newf=${1%.*}.$ext
test -f "$newf" || mv "$1" "$newf"
}

for i in *.txt
do
  test -f "$i" &&
  renamefile "$i"
done

SHTOOL-MOVE.TMP(1)					      GNU Portable Shell Tool						SHTOOL-MOVE.TMP(1)

NAME
shtool-move - GNU shtool enhanced mv(1) replacement SYNOPSIS
shtool move [-v|--verbose] [-t|--trace] [-e|--expand] [-p|--preserve] src-file dst-file DESCRIPTION
This is a mv(1) style command enhanced with the ability to rename multiple files in a single operation and the ability to detect and not touch existing equal destinations files, thus preserving timestamps. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -e, --expand Expand asterisk in src to be used as ""%"n" (where n is 1,2,...) in dst-file. This is useful for renaming multiple files at once. -p, --preserve Detect src-file and dst-file having equal content and not touch existing destination files, thus perserving timestamps. This is useful for applications that monitor timestamps, i.e. suppress make(1L) repeating actions for unchanged files. EXAMPLE
# shell script shtool move -v -e '*.txt' %1.asc # Makefile scanner.c: scanner.l lex scanner.l shtool move -t -p lex.yy.c scanner.c HISTORY
The GNU shtool move command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1999 for GNU shtool. SEE ALSO
shtool(1), mv(1), make(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-MOVE.TMP(1)
