Examples of Shell Scripting
Shell scripting is a powerful tool for automating tasks on your computer. Here are a few examples to help you get started:
1. Automating file backups
Let's say you want to create a automatic file backup system that will run every day at midnight. You can achieve this using shell scripting. Start by creating a script named backup.sh and add the following code:
#!/bin/bash
cd /path/to/backup/folder
tar -czvf $(date +%Y_%m_%d_%H_%M_%S).tar.gz /path/to/files/to/backup
This script will compress and archive all files in the specified directory and save them with a unique timestamp in the backup folder.
Next, make the script executable by running chmod +x backup.sh. To schedule the backup to run every day at midnight, add the following line to your crontab:
0 0 * * * /path/to/backup.sh
2. Web scraping
Web scraping involves extracting data from websites automatically. This can be done by requesting the website's HTML code and parsing it to extract the desired information. Here's an example script that extracts the titles of the top 10 trending repositories on GitHub using curl and grep.
#!/bin/bash
curl -s 'https://github.com/trending' | grep -o '<h1><a.*</a></h1>' | sed 's/<[^>]*>//g'
This script requests GitHub's trending page, greps for HTML tags containing the repository titles, and removes the tags using sed. To save the titles to a file, just add > output.txt to the end of the command.
3. System information
You can use shell scripting to extract system information such as CPU usage, disk space, and memory usage. Here's an example script that displays the current CPU usage.
#!/bin/bash
top -bn1 | grep load | awk '{printf "CPU Load: %.2f\n", $(NF-2)}'
This script uses the top command to extract the current CPU usage and displays it in a formatted string using awk.
These are just a few examples of what you can do with shell scripting. By learning shell scripting, you can automate repetitive tasks, extract data from websites, and extract system information with ease.
Examples of Coding
Coding can refer to a wide variety of programming languages, each with its own unique syntax and purpose. However, for the purposes of this subtopic, we will focus specifically on Python, a popular and user-friendly programming language that is well-suited for beginners.
