Answer 1

sed -i

-iis not described in POSIX, which means it may work differently on different systems.
sed -i.random-backup-tag 's/OldText/NewText/g'should help. Then delete the backups with the command

find  Users/Desktop/Documents \
    -type d -name .git -prune -o 
    -type f -name '*.random-backup-tag' -print0 | \
    xargs -0 rm -f
