# cat /etc/udev/rules.d/99-mydisks.rules

规则用于绑定第一块数据盘

SUBSYSTEM=="block", ENV{ID_SERIAL_SHORT}=="S3ZBND0NC04486A", SYMLINK+="data1"

规则用于绑定第二块数据盘

SUBSYSTEM=="block", ENV{ID_SERIAL_SHORT}=="S3ZBND0NC00073A", SYMLINK+="data2"

运行以下命令以重新加载 udev 规则：
udevadm control --reload-rules

您还可以运行以下命令触发规则立即生效：

udevadm trigger

完成后，您应该能够在 /dev/data1 和 /dev/data2 路径下找到您绑定的两块数据盘。

sed -i "s/abc/123/g" /var/www/test/index.html

# cat udev_disk_rules.sh
#!/bin/bash

AA=$1
BB=$2

RULES_FILE="/etc/udev/rules.d/99-mydisks.rules"

# 创建规则文件，并添加规则
sudo bash -c "cat << EOF > $RULES_FILE
# 规则用于绑定第一块数据盘
SUBSYSTEM==\"block\", ENV{ID_SERIAL_SHORT}==\"$AA\", SYMLINK+=\"data1\"

# 规则用于绑定第二块数据盘
SUBSYSTEM==\"block\", ENV{ID_SERIAL_SHORT}==\"$BB\", SYMLINK+=\"data2\"
EOF
"

# 重新加载udev规则
sudo udevadm control --reload-rules

# 触发规则立即生效
sudo udevadm trigger

echo "完成创建并添加udev规则。"
