[PATCH] ver_linux: sh-utils.patch

[Alexander Kapshuk]

Using 'awk' here is a bit of an overkill. Should the output of 'expr --v'
vary on another disto, or change overtime, it may no longer be available
in the last field, as relied on by the current implementation.
I believe 'sed' offers greater flexibility here in terms of processing
varying output as well as being more light-weight.


Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
openSuSE 13.2
