# Day 5: Basic Linux Shell Scripting (Part-2)

### Let's code something. 😃

On Day 4, we learned about bash scripting. Let's use this knowledge to have some fun on our own *(solutions are at the end)*.

1. Create an output file with the names **DevOpsDays\_1** to **DevOpsDays\_10** using a bash script *(take the filename and the number of days as arguments).*
    
    Output:

2. Create a bash script to back-up your files or folders. (*The script should take two arguments: one for the source file or folder and another for the destination or backup folder).*
    
3. Create a Bash script that counts the number of errors in a report file *(pass the log file as an argument to the script)*.
    
4. Create a Random Joke Generator using the **JokeAPI.***(You may need to install jq to run this script).*
    
5. Create a random password generator (*pass the password length as an argument).*
    
    Output:

*There are other cool methods to create backups. I highly recommend looking into those as well. Some of them are:*

**Using rsync**:

* **Rsync** is a powerful utility for efficiently copying and synchronizing files between directories or systems.
    
* It only transfers the differences between files, making it ideal for backups.
    

**Scheduled Backups with Cron**:

* Set up a cron job to run your backup script at regular intervals (e.g., daily or weekly).
    

**Automated Backup Tools**:

* Consider using tools like **Bacula**, **Amanda**, or **Duplicity** for more advanced backup management.
    
* These tools provide features like encryption, incremental backups, and centralized management.
