  • Introduction to Unix:
    • Unix is a powerful and versatile operating system known for its command-line interface (CLI) and multitasking capabilities.
    • Key features of Unix include file management, process control, networking, and security.
  • Terminal and Shell:
    • Unix commands are executed in a terminal, which provides a text-based interface.
    • The terminal runs a shell, such as Bash (Bourne Again SHell), where you type commands.
  • Navigating the File System:
    • Use the ls command to list files and directories in the current location.
    • Use cd to change directories (e.g., cd /path/to/directory).
    • Use pwd to print the current working directory.
  • File and Directory Operations:
    • Create a new directory: mkdir directory_name.
    • Create a new empty file: touch file_name.
    • Copy files/directories: cp source destination.
    • Move files/directories: mv source destination.
    • Remove files: rm file_name.
    • Remove directories: rm -r directory_name (be cautious with this command).
  • Working with Files:
    • View file content: cat file_name or less file_name.
    • Edit files: Use the text editor vi or nano (e.g., nano file_name).
  • Redirection and Pipes:
    • Redirect output: Use > to overwrite and >> to append (e.g., echo "Hello" > output.txt).
    • Redirect input: Use < to read from a file (e.g., cat < input.txt).
    • Use pipes | to send the output of one command as input to another (e.g., ls | grep keyword).
  • File Permissions:
    • Use chmod to change file permissions (e.g., chmod 755 file_name).
    • Permissions are represented as three sets of characters: owner, group, and others (e.g., rwxr-xr-x).
  • Process Management:
    • View running processes: ps or top.
    • Terminate a process: kill PID (replace PID with the process ID).
  • User Management:
    • Add a user: sudo adduser username.
    • Delete a user: sudo deluser username.
    • Change user: su username.
  • Package Management (Linux-specific):
    • Package managers install and manage software packages on Linux.
    • Common package managers include apt (Ubuntu, Debian), yum (Red Hat, CentOS), and dnf (Fedora).
  • Getting Help:
    • Use man to access the manual pages for commands (e.g., man ls).
    • Online resources like tutorials and forums are valuable for learning Unix.

    • Remember, Unix has a vast array of commands and features beyond what’s covered here. This tutorial provides a foundation for getting started, but continued learning and practice will help you become proficient in Unix. Good luck!

    1. First, make sure you have a microphone connected to your computer. You can use a professional microphone, but if you do not have one of those, you can use your headphones’s microphone instead. Avoid recording with the computer’s built-in microphone, unless you are sure it is a very good one.

    2. To record a new audio with Praat, go to “New” > “Record mono sound”.

    3. A new window will pop up. Leave the default settings, and give the file a name. Then, click “Record” to start recording and “Stop” when you finish.

    4. Don’t forget to save the file before you close the window! PRAAT does not automatically save anything. You can either “Save to list” or “Save to list & Close”. This step will only save your file in the left panel, but you still need to save it in your computer (see step 5).

    5. Finally, to save the file in your computer, click the file’s name on the left panel, and then click “Save” > “Save as WAV file”.
