命令行电池（CLB）-在不编写太难的bash代码的情况下改进bash命令功能的方法。
clb的Python项目详细描述
命令行电池（CLB）
插件驱动的python程序，在不编写太难的bash代码的情况下改进bash命令的功能。
BASH对于备份流水线（如{{CD1>}）来说是好的，但是没有容易的方法来收集流水线中的每个命令的退出代码，关心命令环境，检查超时，通知监控系统，编写令人敬畏的日志，发送通知到SLACK，上传备份到AWS S3等等。有了命令行电池，所有这些东西都可以用了。只需填写yaml配置文件并根据需要更改python脚本文件。这些文件设计得尽可能简单。
特点：
- 每个shell命令的超时时间 检查每个shell命令的退出代码，包括管道中的所有命令<
- shell命令的路径环境变量
- 信息日志
- 松弛通知
- 通过influxDB指标进行监控
- 带有过期策略的aws s3上载
用法
基本用法示例：
example_simple_script.py-cexample_simple_config.yml
2019-05-06 13:38:29,930 INFO in clb.config_parser: Reading config file: example_simple_config.yml
2019-05-06 13:38:29,933 INFO in clb.shell_commands: Running shell command: mkdir -p /tmp/backups

2019-05-06 13:38:29,944 INFO in clb.shell_commands: Running shell command: echo 'THE BACKUP BASH COMMAND' | pigz -p 4 -4 > /tmp/backups/current_backup.gz
2019-05-06 13:38:29,963 INFO in clb.shell_commands: Shell command success
2019-05-06 13:38:29,964 INFO in clb: Commands completed

安装
最简单的方法：
下载并运行安装脚本（python2/3）：
$ wget -O /tmp/install_clb.py https://raw.githubusercontent.com/sharkman-devops/command_line_batteries/master/install_clb.py
$ sudo python /tmp/install_clb.py
创建cron作业（crontab-e）：
51 23 * * * /opt/command_line_batteries/venv/bin/python /opt/command_line_batteries/example_script.py -c /opt/command_line_batteries/example_config.yml >> /var/log/command_line_batteries/example.log 2>&1
别忘了填写example_config.yml并检查example_script.py以获取所需的逻辑！
更灵活的方式：
创建安装目录：
mkdir -p /opt/command_line_batteries
创建虚拟环境：
python3 -m venv /opt/command_line_batteries/venv
激活虚拟环境：
source /opt/command_line_batteries/venv/bin/activate
安装命令行电池：
pip install clb --upgrade
下载示例脚本和配置：
wget -O /opt/command_line_batteries/example_script.py https://raw.githubusercontent.com/sharkman-devops/command_line_batteries/master/example_script.py
wget -O /opt/command_line_batteries/example_config.yml https://raw.githubusercontent.com/sharkman-devops/command_line_batteries/master/example_config.yml
使示例脚本可执行：
chmod +x /opt/command_line_batteries/example_script.py
创建日志目录：
mkdir -p /var/log/command_line_batteries
创建cron作业（crontab-e）：
51 23 * * * /opt/command_line_batteries/venv/bin/python /opt/command_line_batteries/example_script.py -c /opt/command_line_batteries/example_config.yml >> /var/log/command_line_batteries/example.log 2>&1
别忘了填写example_config.yml并检查example_script.py以获取所需的逻辑！
兼容性
环境应包括：
- 击壳
- awk
- python 3.6或3.7
在gnu-linux上使用gnu-bash 4、gnu-awk 4和python 3.6&；3.7测试命令行电池
