Complete Tasks: Log analysis, file permissions, and email/password Bash script

[zahid-0x80]

This pull-request provides solutions for the three tasks from the BongoDev repo:

Task 1: Log Analysis

• Created a log file app.log with at least 10 lines, including INFO, DEBUG, and 3 ERROR lines.
• Wrote a Bash script find_errors.sh that reads app.log and extracts only the lines containing ERROR.
• Verified the script output.

Task 2: File Permissions and Ownership

• Created a directory project and a file notes.txt inside it.
• Added sample text to notes.txt.
• Checked initial permissions with ls -l.
• Modified permissions: removed write permission for the group and added execute permission for the owner (chmod 744 notes.txt).
• Changed ownership of notes.txt to root and verified.
• Displayed final permissions and ownership.

Task 3: Read and Print Email/Password

• Created a Bash script read_email_password.sh that prompts the user to enter their email and password.
• Prints a confirmation message showing the entered email and password.

All scripts are tested locally and ready for contribution.
