Batch-rename downloaded video lectures

To batch-rename downloaded video lectures efficiently, follow these steps based on your operating system:

Windows (Using PowerShell)

1. Open PowerShell in the folder where your videos are stored.

2. Use the following script to rename files with a specific pattern:

powershell
CopyEdit
$i = 1
Get-ChildItem -Filter *.mp4 | Sort-Object Name | ForEach-Object {
    $newName = "Lecture_$i.mp4"
    Rename-Item $_.FullName $newName
    $i++
}

Modify "Lecture_$i.mp4" to your preferred format, such as "CourseName_Lecture_$i.mp4".

macOS/Linux (Using Terminal/Bash)

1. Open Terminal in the directory of your files.

2. Run this command to rename .mp4 files:

bash
CopyEdit
a=1
for i in *.mp4; do
  new=$(printf "Lecture_%02d.mp4" "$a") # 2-digit numbers
  mv -- "$i" "$new"
  let a=a+1
done

You can adjust "Lecture_%02d.mp4" as needed.
