## pip升级
```shell
#清华源
#默认超时时间很短
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip -U
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
#修改配置
vim .config/pip/pip.conf
[global]
timeout = 60
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

#豆瓣源
[global]
timeout = 60
index-url = https://pypi.douban.com/simple

#http需要加这句
#trusted-host = pypi.douban.com

#windows
python -m pip install --upgrade pip

#记录依赖问题
cffi依赖
sudo apt-get install libffi-dev

```

## sqlite3
```shell
sqlite3 db.sqlite3
.databases
.tables
sqlite3 testDB.db .dump > testDB.sql
#.read gendata.sql
sqlite3 testDB.db < testDB.sql
```

## markdown
去空行
```
打开VSCODE，Ctrl+h点开正则匹配，把    ^\s*$\n^\s*$\n 替换为 \n
^\s*$\n 替换为 空
```
## linux
```shell
#Vim批量注释
Ctrl+v I # Esc

#检测端口占用的进程
lsof -i  :80
lsof -i  :3306

#寻找软件包
yum  provides  nslookup
yum -y install bind-utils
nslookup 11n.wang

#日期操作
date=`date  +"%Y.%m.%d %H:%M:%S"`
date=`date  "+%Y.%m.%d %H:%M:%S"`
echo "now is: "$date
#DATE=`date -d "-$i days" +"%Y.%m.%d"`

#分卷压缩
echo kibana.tar.gz > splitname
split -db 90m kibana.tar.gz   #(文件名)

zip -r -s 90m aaa.zip aaa   #（目录或文件）
zip -s 0 aaa.zip --out abc.zip

#echo -e的作用
echo -e '\n192.168.0.143 node1\n192.168.0.93 master1' >> /etc/hosts

sh  -x 查看执行过程

#注意src的/
rsync -aP --delete f1/ f2/

#image后面的内容全部替换
sed  -i 's#image:.*#image:nginx 2.0#g' test.txt


#查找包含mmbiz.qpic.cn的文件清单
find . -type f  -exec  grep -ril "mmbiz.qpic.cn" {} \;
#查找包含mmbiz.qpic.cn的文件内容
#这里不用加-type f
find .   -exec  grep -ri "mmbiz.qpic.cn" {} \;

#find搭配sed
#用\转义  [也需要转义，为什么    -name后面的""不能少  
find . -name "*.md" -exec sed -i 's/\[](res/\[](.\/res/g' {} \;

find . -type f -exec sed -i 's#../img/#https://share-1300858685.cos.ap-shanghai.myqcloud.com/images/#g' {} \;

#遇到文件名有空格无法处理
find . -type f |xargs -i sed -i 's#https://share-1300858685.cos.ap-shanghai.myqcloud.com/images/#../img/#g' 
#xargs处理特殊文件名
find /root/blog -type f -print0 |xargs -0 sed -i 's#../img/#http://iubest.gitee.io/pic/#g'

find . -name '*.txt' -type f -print0 | xargs -0  cat

#确认 master 节点是否有 Taint，如下看到 master 节点有 Taint。
kubectl describe node k8s-master | grep Taint
Taints:             node-role.kubernetes.io/master:NoSchedule
#去掉 master 节点的 Taint：
kubectl taint nodes k8s-master node-role.kubernetes.io/master:NoSchedule-

#默认存储类
kubectl patch storageclass nfs-storage -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

#暴露NodePort服务端口
#方法1：
kubectl delete svc mysql57 -n mysqltest
kubectl expose deployment mysql57  --port=3306 --type=NodePort -n mysqltest
#方法2：
也可以使用kubectl edit直接修改type为NodePort

#命名空间插件
git clone https://github.com.cnpmjs.org/ahmetb/kubectx
cp kubectx/kubens /usr/local/bin
#查看所有命名空间
kubens
```
## Python
```
import os
tmp=os.popen("ip a|grep inet")
print(tmp.read())
tmp.close()
