Import git history

Robin Michael

• 1 min read

Need to import the git history of one repository into another due to consolidation of several separate microservices into a single vertical slice service.

Example

I have a repository called infra and I want to import the history of commits into the new current folder as it holds my consolidated repository. Need to get the git content by applying git ls-tree to each file element is the goal.

Bash

  • git ls-tree --name-only HEAD | grep -v '^infra$' | xargs -I {} git mv {} infra/

PowerShell

Unfortunately there is no grep or xargs to help me out here and the unix approach of using .hidden for files and folders means git history can get imported so need to skip those files hence the need for the ^$folder$|^\." -notMatch

  • $folder = "infra"; git ls-tree --name-only HEAD | Select-String -pattern "^$folder$|^\." -notMatch | ForEach-Object { Move-Item $_ -Destination #$folder/$_"
