$ python3 -m venv .venv  # requires python 3.7 or higher
$ source .venv/bin/activate
$ pip install -r requirement.txt
$ ./script/build/package_exec # used pyinstaller build single binary file.
$ ./dist/pypssh --version

# or according to the old version of the configuration conversion to the new version of the configuration file
$ pypssh config convert config/old_inventory.conf  > /root/.pypssh/inventory/inventory.yaml

# use -t to select the host to execute the command
$ pypssh -t 192.168.1.100 execute -e NAME=peter 'echo hello $NAME'

# use -t to select host slices and list the hosts in the configuration
$ pypssh -t 192.168.3[2:90].10[5:9] ls

# use -t to select the host slice with a list and list the hosts in the configuration
$ pypssh -t 192.168.32.1[5:9,32,35,38] ls

# use -t to select the host with the master tag to upload files
$ pypssh -t master put [localfile] [remotefile]

# use -t to select the host with the mysql==master tag to upload files
$ pypssh -t mysql==master get [remotefile] [localdir]

# use -t to select the host where the complex label expression evaluates to True to upload files
$ pypssh -t 'ds01 and (redis==master or mysql)' execfile test.py

runtime dependency：

• paramiko/scp: Provide ssh/scp client support.
• jinja2: Provide template rendering support when outputting command results.
• marshmallow_dataclass: Provide support for dataclass conversion to dict;
• click: Provide cli support.
• PyYAML: Provide yaml configuration file parsing support.
• tenacity: Provide retry support.

development dependency：

• altgraph: Provide alt module debugging support.
• autopep8: Provide code formatting support.
• PyInstaller：Provide binary program release support.

• The import statement is written in accordance with the following specifications：
  • Built-in packages are listed in front of dependent packages.
  • The short package name comes before the long.
  • import ... comes before from ... import
• By default, ~/.pypssh/ is used as the data directory to store its own data and configuration files.
• The output of the subcommand uses echo(output_mode:str, cls, datas, template) or click.echo(yaml.dump({{result}}, allow_unicode=True)).
• Use get_ssh_logger(host) in the ssh task function to get the log instance, so that the host name can be printed in the header of each log.
