Single-line command statements are the norm on Linux command lines. However, sometimes we may need, or simply find it efficient, to run multiple commands from the prompt. In this tutorial, we’ll look at various methods for running multi-line commands from a single command-line prompt. 2. ...
Put all of your commands in a wrapper script, complete with testing and debugging information. Run the wrapper script as yourCMD. The following is a naive example. First, the wrapper script: #!/bin/bash# Start the first process./my_first_process Start the second process./my_second_process...
In the above example, echo will still run despite the error caused by the name resolution in the ping command. Here is a screenshot illustrating this: NOTE:You can tie multiple commands using bash operators to achieve the best result. For example, you can allow sleep to execute only if pi...
Run Bash commands using Python Popen Popen is used for complex commands, such as pipe commands in bash. Lets try a simple pipe command first. p = subprocess.Popen(['ls','-ld','/home'],stderr=subprocess.PIPE, universal_newlines=True,stdout=subprocess.PIPE)out,err = p.communicate() ...
