Executing a shell script with arguments from a python script

Question

My Shell script is executed like this from the command line

./pro.sh "Argument1"

I am calling it from my python script currently like this

subprocess.call(shlex.split('bash pro.sh "Argument1"'))

How do I pass the value of Argument1 as a variable. My argument to the script can be any string. How do I achieve this?

Answer 1

使用子进程调用您的Shell脚本

subprocess.Popen(['run.sh %s %s' % (var1, var2)], shell = True)

Answer 2

You can use

subprocess.Popen(["bash", "pro.sh", "Argument1"])

If your string argument is multiple words, it should work fine.

subprocess.Popen(["bash", "pro.sh", "Argument with multiple words"])

As long as the multiple words are in one string in the list passed to subprocess.Popen() , it is considered one argument in the argument list for the command.

You should not use shell=True unless you have a good reason. It can be a security problem if you aren't very careful how it is used.
