Portability. "env |grep" is POSIX standardized so should work everywhere. printenv is a BSD invention, which not all unix variants are required to have. (Besides, printenv on its own cannot do "give me all environment variables that start with 'with_'", which is exactly what we want here... so you'd end up with "printenv | grep", which is less portable and more characters) gert -- "If was one thing all people took for granted, was conviction that if you feed honest figures into a computer, honest figures come out.
