Question

I have a rather large SQL file which starts with the byte order marker of FFFE. I have split this file using the unicode aware linux split tool into 100,000 line chunks. But when passing these back to windows, it does not like any of the parts other than the first one as only it has the FFFE byte order marker on.

How can I add this two byte code using echo (or any other bash command)?

Answer 1

Something like (backup first)):

for i in $(ls *.sql)
do
  cp "$i" "$i.temp"
  printf '\xFF\xFE' > "$i"
  cat "$i.temp" >> "$i"
  rm "$i.temp"
done
