Aside from the file-naming convention... is there a way to do this multiple times in a row, using a single script? In other words, i = i + (1..299) - each time saved as a new file?
Hello pseudo.seppuku,

Could you please try following and let me know if this helps, not tested though.
Code:
for file in *.txt; do let "i = i + 1"; awk -vI=$i '{gsub(/001/,"002",$0);VAL=sprintf("%02d",I);print >> FILENAME VAL;}' $file; done

Thanks,
R. Singh
