Here is an AWK script that may help you. You can download GNU AWK from here: https://sourceforge.net/projects/ezwinports/files/gawk-4.1.3-w32-bin.zip/download
# **************************************************************************
# AWK script to replace all occurences of FindStr with RepStrNNN.
# Output files are the same name as the input files with ".ed" appended.
#
# Run it like this: gawk -f .\thisScript.awk <files to be edited>
#
# If this file is saved as repAll.awk in the current directory, and the
# files to be edited are in directory c:\fileDir, then:
#
# gawk -f .\repAll.awk c:\fileDir\*
#
# **************************************************************************

# If FindStr contains any characters that have special regex meaning,
# they must be prefaced with "\". For example: "Needed\* Here".

# Controls leading zeroes, but does not
# limit the total number (i.e. if there
# are 10000+ replaces, then ID10134, for
# example, will be generated).
Number = 0 # Initial number to append.
BatchFile = ".\\CopyAndDel.bat" # Name of batch file used to clean up.
