How to Run bash scripts Using Python?

If you are using Linux, then you would definitely love the shell commands.

And if you are working with Python, then you may have tried to automate things. That’s a way to save time. You may also have some bash scripts to automate things.

Python is handy to write scripts than bash. And managing Python scripts are easy compared to bash scripts. You will find it difficult to maintain the bash scripts once it’s growing.

But what if you already have bash scripts that you want to run using Python?

Is there any way to execute the bash commands and scripts in Python?

Yeah, Python has a built-in module called subprocess which is used to execute the commands and scripts inside Python scripts. Let’s see how to execute bash commands and scripts in Python scripts in detail.

A Shell Script to Copy All files with Same Structure

This shell script is designed for a specific task required for our server. So sharing the script with Tecadmin readers. It might be helpful for you.

Requirement

Our requirement is to copy all files created in directory to other directory with same directory structure. Script will run on a regular interval, search for all files created in source directory and copy them to destination directory. The script must maintain the same directory structure on destination directory. After that change the permission on destination directory. After successful copy of file, script must remove the file from source directory.

Shell Script

Create a shell script on your system and add below content. Update source and destination directories to proper location.

Set CHANGE_OWNERSHIP to 0, if you don’t want to change ownership on destination files.

#bash shell #bash #shell script

Linux Sleep Command (Pause a Bash Script)

sleep is a command-line utility that allows you to suspends the calling process for a specified time. In other words, the sleep command pauses the execution of the next command for a given number of seconds.

The sleep command is useful when used within a bash shell script, for example, when retrying a failed operation or inside a loop.

In this tutorial, we will show you how to use the Linux sleep command.

How to Use the sleep Command

The syntax for the sleep command is as follows:

sleep NUMBER[SUFFIX]...

Copy

The NUMBER may be a positive integer or a floating-point number.

The SUFFIX may be one of the following:

  • s - seconds (default)
  • m - minutes
  • h - hours
  • d - days

When no suffix is specified, it defaults to seconds.

When two or more arguments are given, the total amount of time is equivalent to the sum of their values.

#sleep #linux sleep #bash script #bash

Shell Scripting Quick Beginner’s Guide

Shell Script is a program designed to run in the Unix/Linux shell. We can write a particular set of commands as a script and run it to perform some tasks.

We can run Unix/Linux command on Windows, Mac using a Bash (Bash is a command-line interpreter or a shell) like Git Bash or any other program. We can ls to list content in a directory, touch to create files.

Image for post

So, let’s create a file with .sh extension to write some script and open it with your favorite text editor. Also, open up the terminal or Git Bash if you are using windows.

First, we have to make our script executable. Unless if we run it, we’ll get permission denied error. To do that run chmod +x testscript.sh command in the terminal. By this command, we change the mode to executable (we give the permission to execute).

To run the script, run the command ./testscript.sh in the terminal. It will not give you any output because the file is still empty.

In our script (testscript.sh), first we have to declare the _dialect, _I’m using Bash. In the terminal run the command which bash to find the location of bash in your computer. In the top of your script type #! <BASH_LOCATION> to declare the bash.

#terminal #bash #linux #shell-script #shell
