介绍
一个subprocess模块的封装,可以更方便的进行系统调用
To Do List:
- return realtime result
- task async run
[开发easyrun的环境是python3哦]
安装
pip安装
pip install easyrun
源码安装
git clone git@github.com:rfyiamcool/easyrun.git
cd easyrun
python setup.py install
使用方法
只单纯的执行,然后返回linux run code和执行状态
>>> import easyrun
>>> r = easyrun.run('uptime')
04:06:37 up 2 min, 1 user, load average: 0.20, 0.19, 0.08
>>> r.output
>>> r.success
True
>>> r.retcode
0
捕捉所有的执行结果
>>> r = easyrun.run_capture('uptime')
>>> r.output
' 04:07:16 up 2 min, 1 user, load average: 0.11, 0.17, 0.08\n'
>>> r.success
True
>>> r.retcode
0
把输出的结果精简过,maxlines是控制行数
print(run_capture_limited('ls', maxlines=2).output)
easyrun example usage:
from easyrun import run_capture
r = run_capture('ls -la')
if r.success:
print(r.output)
else:
print("Error: '%s' exit code %s" % (r.command, r.retcode))
print(" ...")
# print last three lines of output
for line in r.output.splitlines()[-3:]:
print(" %s" % line)
