PYSH

pysh是一个基于Python语法的脚本解释程序。

安装

pip install pysh-run

使用方法

  1. 基本用法

    from pysh.lib import Exec
    print(Exec("ls").stdout())
  2. 管道

    from pysh.lib import Exec
    print(Exec("cmd1").pipe_to(Exec("cmd2")).stdout())
    print((Exec("cmd1") | Exec("cmd2")).stdout())  # 使用管道运算符
  3. 正则过滤

    from pysh.lib import Exec, Filter
    print(Exec("cmd1").pipe_to(Filter(".*\\.ps")).stdout())
    print(Exec("cmd1").pipe_to(func).stdout())  # func的参数为cmd1的输出,输出结果为func的返回值
  4. xargs

    from pysh.lib import Exec
    Exec("lsof -i:8080").pipe_to("kill -9 $[1,1]").exec()  # 前一个命令的输出内容作为后一个命令的参数
  5. &&

    from pysh.lib import Exec
    print(Exec("cmd1").success_to(Exec("cmd2")).stdout())  # cmd1执行成功才执行cmd2
  6. ||

    from pysh.lib import Exec
    print(Exec("cmd1").fail_to(Exec("cmd2")).stdout())  # cmd1执行失败才执行cmd2
  7. from pysh.lib import Exec
    print(Exec("cmd1").stream_to(Exec("cmd2")).stdout())  # 同时启动两个进程,把cmd1的输出实时写入cmd2
    print(Exec("cmd1").stream_to(func).stdout())  # cmd1每输出一行,func被调用一次
