Dear kernel programmer,
while writing some shell script (bash) I dicovered a bug in some of /proc/sys/kernel/* files. Some of these files have a null character followed by a newline in them like "...\0\n". I think this should be reversed as in "...\n\0" or leave out null character completely "...\n".
Difficults arise when you try to read a value with a bash command...
read RELEASE </proc/sys/kernel/osrelease
but bash (version 1.14.4) assigns an empty value to RELEASE. You may try this yourself...
for i in /proc/sys/kernel/*; do echo $i:; od -c $i; done
in bash. Here is what I'll get (stripped down, edited and commented).
/proc/sys/kernel/domainname: ( n o n e ) \0 \n ^^^^ /proc/sys/kernel/hostname: k o p p e n a s \0 \n ^^^^ /proc/sys/kernel/osrelease: 1 . 3 . 9 9 \0 \n ^^^^ /proc/sys/kernel/ostype: L i n u x \0 \n ^^^^ /proc/sys/kernel/version: # 1 3 T h u M a y 9 0 8 : 4 3 : 0 5 M E T D S T 1 9 9 6 \0 \n ^^^^ IMHO this is not a feature - it a bug!
