Answers for "python run bash command execute shell"


executing shell commands from python script

import subprocess["bash", ""])
#we don't have to give full path to the shell script. It always execute from the current directory

#As a rule of thumb, you need to separate the arguments based on space, 
#for example ls -alh would be ["ls", "-alh"], while ls -a -l -h, 
#would be ["ls", "-a", -"l", "-h"]. As another example, 
#echo hello world would be ["echo", "hello", "world"], 
#whereas echo "hello world" or echo hello world would 
#be ["echo", "hello world"].

#Another example.
list_files =["ls", "-l"])
print("The exit code was: %d" % list_files.returncode)
