More than one guide uses this pattern: 'cat foo | grep bar;' when 'grep bar foo;' would probably be a slightly better choice. Reproducible: Always Steps to Reproduce: Sorry to be so anal, but Gentoo teaches so many *n?x users their practices, I felt that I should at least bring it up.
sorry, forgot to mention that one example of what I'm talking about is http://www.gentoo.org/doc/en/power-management-guide.xml Code Listing 3.1 cat /proc/cpuinfo | grep "cpu MHz" could be grep "cpu MHz" /proc/cpuinfo
there were three occurences of that, fixed them all thanks :)
