In Windows PowerShell, you can delete all branches except main or master branch of a git repository using the following command

git branch | Where-Object { $_ -notmatch "master" -and $_ -notmatch "main" } | ForEach-Object { git branch -D $_.Trim() }

Explanation:

  • git branch: Lists all branches.
  • Where-Object { $_ -notmatch "master" -and $_ -notmatch "main" }: Filters out the branch named master or main using PowerShell’s pattern matching.
  • ForEach-Object { git branch -D $_.Trim() }: Iterates over each remaining branch name, trims any extra whitespace, and deletes it with git branch -D.
