2.1subprocess.run(Python 3.7+) subprocess.run是推荐的方式,因为它提供了简洁的API并且功能强大。 importsubprocess# 调用简单的Bash命令result=subprocess.run(['ls','-l'],capture_output=True,text=True)# 输出结果print("stdout:",result.stdout)print("stderr:",result.stderr)print("returncode:",result....
subprocess.run(['ls','-ld','/home1'], stdout=subprocess.PIPE, universal_newlines=True) CompletedProcess(args=['ls','-ld','/home1'], returncode=2, stdout='') Run Bash commands using Python Popen Popen is used for complex commands, such as pipe commands in bash. Lets try a simple ...
result=subprocess.run("echo hello",capture_output=True,text=True,shell=True)print(result.stdout) 1. 2. 在这个例子中,我们使用了subprocess.run()函数执行了一个使用Shell语法的命令echo hello。shell=True参数用来启用Shell语法。 总结 通过subprocess模块,我们可以在Python中执行Bash命令,并获取命令的输出。我们...
以下是一个Python脚本示例,它以交互方式运行多个Bash命令: 代码语言:txt 复制 import subprocess # 运行Bash命令并交互 def run_bash_commands(): commands = [ 'echo Hello, World!', 'ls -l', 'pwd' ] for command in commands: print(f"Running command: {command}") process = subprocess.Popen(comman...

(3)commands.getstatus(file),返回ls -l file的执行结果字符串,调用了getoutput,不建议使用此方法 4. subprocess subprocess模块,允许创建很多子进程,创建的时候能指定子进程和子进程的输入、输出、错误输出管道,执行后能获取输出结果和执行状态。 (1)subprocess.run():python3.5中新增的函数, 执行指定的命令, 等待...
bash shell查找命令顺序: ==>以路径(绝对路径,相对路径)开始命令,例如:/bin/ls 或 cd /bin; ./ls ==> alias ==> Compound Commands ==> function ==> build_in,如cd,kill,pwd、alias、echo等,可以用"type -a 命令"查看 ==> hash ==> $PATH,环境变量,查看环境变量echo $PATH,例如/bin/ls ==...
