Point being, you have to write your own w command in shell script when using sed, and some people choose to for awk as well.. Which means dealing with temporary files by hand. For those who think it's simple, $ command file > file.bak && mv file.bak file is not perfect for every situation.

You know, fewer moving parts the fewer things that can break.
