I ran the following to replace a term used in all files in the current working directory:
$ find . -type f -print0 | xargs -0 sed -i'.bup' -e's/Ms. Johnson/Mrs. Melbin/g'
This performed the word substitution but it also created
.bup files of files that never had the
Ms. Johnson string.
How do I perform the substitution without creating all these unnecessary backups?
