更新内核后检测grub配置文件

  有时从源更新内核后grub的配置文件有点问题造成重启后无法启动。尤其是远程更新重启后比较麻烦。写了个脚本可以检测grub2的配置文件

#!/bin/bash
end="\e[0m"
red="\e[1;31;40m"
ver="\e[1;32;40m"
yel="\e[1;33;40m"
blu="\e[1;34;40m"
pur="\e[1;35;40m"
gre="\e[1;36;40m"
whi="\e[1;37;40m"
filein=/boot/grub/grub.cfg
fileout=/var/tmp/$$.list
echo -e "${pur}checking the kernel image file${end}"
grep "vmlinuz" $filein|awk '{print $2}'|uniq >$fileout
grep "initrd" $filein|awk '{print $2}'|uniq >>$fileout
cat $fileout
echo -e "${pur}test the image file${end}"
error=0
while read i
do
if [ ! -s $i ];
then
printf "error! can't find $red%s$end\n" $i
error=$((++error))
fi
done <$fileout
rm -rf $fileout
if [ $error -gt 0 ]
then
echo -e "there is some wrong with the file:" $yel$filein$end
else
echo  -e "${blu}OK,all is good!${end}"
fi
