Hello,
Having run 'scripts/ver_linux' on my Gentoo system, as well as having
looked through some recent bug reports on the kernel bugzilla website
showing the output of the script in question, I have observed that
the output is not accurate across various distros. While the current
implementation of the script expects the version info to be found in
particular fields, some of the utilities invoked by the script, output
their version information in varying formats, which results in the
script displaying information other than the version number.
The proposed implementation relies mostly on sed to detect the version
numbers more accurately. Running the patched version of the script on
the distros below resulted in accurate and uniform output.
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
The items left unchanged are those I did not have access to. I would
be willing to work on those too, if supplied the output of the affected
commands whose format differs based on the distro.
-------------------------------------
A few comments are in order.
/usr/src/linux/scripts/ver_linux.orig:22,26
The current implementation
outputs the version of 'util-linux' by calling 'fdformat', which had
not been found installed on most of the test systems available to me. As
'mount' is a part of the 'util-linux' package, the proposed implementation
invokes 'mount' only, and unifies the lines above into a single block.
/usr/src/linux/scripts/ver_linux.orig:77,83
'loadkeys -h' does not output
the version number across all the test systems available to me, while
'loadkeys -V' does. The proposed implementation calls 'loadkeys -V'
only once, and outputs the version info acquired for both 'Kdb' and
'console-tools'.
/usr/src/linux/scripts/ver_linux.orig:90
None of the test systems I
have access to seem to have 'udevinfo' installed. Perhaps, 'udevinfo'
is the former name for something that could now be substituted by
'udevadm --version'.
-------------------------------------
Sample output of the current implementation on Gentoo Linux:

If some fields are empty or look unusual you may have an old version.
