in reply to sed deleting file

This is not sed(1) overwriting the output file, it is the shell. Redirection  > pbxiplp1 is a shell operation - if the file already exists it clobbers it (truncates to zero bytes). This is done by the shell before the sed(1) program is executed. By the time poor old sed gets to read the file the data is long gone.

Use perl for this, or redirect to a different filename then rename it. Misread the question.
