Import

from plinux import Plinux

Usage

The most recommended usage way:

from plinux import Plinux

client = Plinux(host="172.16.0.124", username="bobby", password="qawsedrf")
response = client.run_cmd("hostname")
print(response.stdout)  # WebServer
print(response.ok)  # True

from plinux import Plinux

client = Plinux()
response = client.run_cmd_local("hostname")
print(response.stdout)  # WebServer
print(response.ok)  # True

Command using sudo:

from plinux import Plinux

client = Plinux(host="172.16.0.124", username="bobby", password="qawsedrf", logger_enabled=True)
response = client.run_cmd("systemctl stop myservicename.service", sudo=True)

print(response)  # SSHResponse(response=(0, None, None, "sudo -S -p '' -- sh -c 'systemctl stop myservicename.service'"))
print(response.command)  # sudo -S -p '' -- sh -c 'systemctl stop myservicename.service'
print(response.exited)  # 0

SFTP usage:

from plinux import Plinux

tool = Plinux(host="ftp.test.local", username="bobby", password="qawsedrf")
sftp = tool.sftp
print(sftp.listdir())

SQLite3 usage:

from plinux import Plinux

client = Plinux(host="cdn1.test.local", username="bobby", password="qawsedrf")

db_path = '/opt/ProductName/rxdb/StorageConfig.db'
sql = 'select Data from DtoDataContainer'
db = client.sqlite3(db_path, sql).json()
print(db)  # {"Settings1": 1, "Settings2": 2...,"Settings10": 10}
print(db['Setting1'])  # {"Settings1": 1}

Aliases

Some methods have "human commands" and aliases:

• client.run_cmd("cat /home/bobby/text")
• client.cat("/home/bobby/text")
