All wikis in an Azure DevOps project are stored as git repositories. I wanted to use Find and Replace to make an update across many files, but this isn't possible through the Azure DevOps web UI. I cloned the repository locally, made my change, and committed it. That's when I ran into an interesting gotcha.

The branch which is used to display the wiki is not called master. It's called wikiMaster. I didn't think to check this, and pushed my changes to origin/master (creating the branch in the process thanks to a nifty git alias I use for pushing changes, as I usually do want to create a branch if it doesn't already exist).

Once I realised the branch name was wrong, the fix was simple:

• I checked out the correct branch:

git checkout wikiMaster

• I merged in my changes:

git merge master

• I pushed the wikiMaster branch:

git push

• I deleted the branch I'd unintentionally created on the server:

git push -d origin master

Job done!
