## Remove information changed by regeneration of load command:
## - __LINKEDIT segment filesize may change (4 lines)
## - LC_CODE_SIGNATURE command dataoff and datasize may change (3 lines)
## - __LINKEDIT data locations may change
## NOTE: The {N;N;N;N;d} means delete the next four lines for BSD and GNU sed.
## The ,+4d is a GNU extension which seems not to work in macOS 10.15
