shell脚本使用记录一：操作文件

一，连接远程数据库（保证在服务器上能使用mysql命令行，至少要安装mysql客户端）

#!/bin/bash
HOSTNAME="ip"
PORT=""
USERNAME="username"
PASSWORD="password"
DBNAME="test"
TABLENAME="shell_test"
insert_sql="insert into $TABLENAME values(NULL,'billchen',2)"
mysql -h$HOSTNAME  -P$PORT  -u$USERNAME -p$PASSWORD $DBNAME -e  "$insert_sql"

二，遍历文件夹，并输出该文件夹下所有的所有文件夹信息(计算文件夹大小)

#!/bin/bash

#function:new ls
#author:reed

Files=$1
if [ $# -eq 1 ];then
        for FileList in $(find $1);do
                FileType=$(ls -lhd $FileList |awk -F' ' '{print $1}'|cut -c 1)
                if [ "$FileType" == d ];then
                        DirSize=$(du -sh $FileList|awk '{print $1}')
                        ls -lhd $FileList|sed "s/[^ ]\+/$DirSize/5"
                else
                        ls -lh $FileList
                fi

        done
else
        echo "--usage:$0 +[directory] or [file];"
        echo "--example:$0 /root"
fi

如果想把这些信息输入到文件中：

#!/bin/bash

#function:new ls
#author:reed

Files=$1
if [ $# -eq 1 ];then
        for FileList in $(find $1);do
                FileType=$(ls -lhd $FileList |awk -F' ' '{print $1}'|cut -c 1)
                if [ "$FileType" == d ];then
                        DirSize=$(du -sh $FileList|awk '{print $1}')
                        ls -lhd $FileList|sed "s/[^ ]\+/$DirSize/5" >> /root/yaming/vedio-log/mylog.txt
                else
                        ls -lh $FileList >> /root/yaming/vedio-log/mylog2.txt
                fi

        done
else
        echo "--usage:$0 +[directory] or [file];"
        echo "--example:$0 /root"
fi

如果还想把上面文件中的信息存入数据库中：

#!/bin/bash

Host="ip"
TABLE="statistics_storage"
passwd="password"
filename=`date +%Y-%m-%d.txt`
cat /root/yaming/vedio-log/${filename}|tr " " "," > /root/yaming/vedio-log/${filename}
cat /root/yaming/vedio-log/${filename} | sed 's/^/NULL\t/g' |sed 's/\t/,/g' >> /root/yaming/vedio-log/${filename}
cat /root/yaming/vedio-log/${filename} |while read line
do
echo $line
query=`echo "$line" |awk -F ","  '{ printf("%s,\"%s\",\"%s\",\"%s\",\"%s\",\"%s\",\"%s\",\"%s\",\"%s\",\"%s\"", $1, $2, $3, $4, $5, $6, $7, $8, $9, $10)}'`
echo $query
mysql -h$Host dbname  -u username -p$passwd  <<EOF
INSERT INTO $TABLE VALUES($query);
EOF
done
