data.txt

7    jerry    1991-12-13    man
8    mike    1991-12-13    women
9    tracy    1991-12-13    man
10    kobe    1991-12-13    man
11    allen    1991-12-13    women
12    curry    1991-12-13    man
13    tom    1991-12-13    women　　

db_import.sh

#!/bin/bash
#

db_user="teacher"
db_password="123456"

mysql_conn="mysql -uteacher -p$db_password"

cat data.txt | while read id name birthday sex

do

if [ $id -gt 10 ];then
$mysql_conn -e "insert into student.class values($id,‘$name‘,‘$birthday‘,‘$sex‘)"
fi
done

将data.txt和db_import.sh放到同一个目录，命令行执行下面命令

sh db_import.sh

其他：如果文本中的分割符不是空格，是“|”，则在脚本加一行IFS=|（默认分割符为空格和table）
