The problems I have are: 1. Should be in ports Not pre-installed on Linux, why should we have it in base? If in base, people will target it thinking it solves a need that can't otherwise be solved and thus end up creating a script that is less portable because it is encumbered with dependencies specific to our base. 2. Teaches bad practice sed ... somefile | sponge somefile Ignores if there is a sed error and indiscriminately zeroes somefile. 3.
