shell解压压缩

1. 压缩：

tar -cjvf xxx.tar.bz2 xxxx

2. 解压：

（解压到指定目录）

tar -xjvf 2018-10-21.tar.bz2 -C /mysql/

# 3. 归档
tar -czvf xxxx.tar.gz xxxx

# 4. 解压
tar -xzvf xxxx.tar.gz

# 5. pigz
压缩：time tar -cf - /tmp/hadoop | pigz -6 -p 8 -k> hadoop.tgz
```
-0 to -9, -11 : 压缩级别
-p n : 指定压缩核心数，默认8个
-k :压缩后保留原文件
```
解压：time pigz -p 8 -d hadoop.tgz

# 5. lz4压缩、解压
压缩：tar cvf - path/to/dir | lz4 - dir.tar.lz4

解压：lz4 -d dir.tar.lz4 | tar -xv

# 5. curl

## 上传文件
curl -XPOST http://100.67.76.9:10030/v2/UploadScripts?token={token} -F "file=@./monitor.tgz"

## 带有body
curl -X POST http://100.67.76.9:10030/v2/UploadScripts?token={token} -H "Content-type: application/json" -d '{"key1": "value1", "key2": "value2"}'

curl -X POST http://100.67.76.9:10030/v2/UploadScripts?token={token} -H "Content-type: application/json" [email protected]

# 6. 清空history
echo "" > ~/.zsh_history & exec $SHELL -l
history -c

# 压缩对比
