拦截用户输入的 reboot 命令，防止手滑输入成reboot导致服务器重启
把下面代码写入到 /etc/profile 内,并执行一次 source /etc/profile
# 自定义一个 func
sendya_reboot() { while true do echo -n "You really want to restart the server? (yes/no):" read crm if [ "$crm"x = "yes"x ]; then echo "rebooting" reboot else break fi break done } # 别名 alias reboot='sendya_reboot'
