Removing deleted remote branches from local repo

Sometimes we have a POC(Proof of concept) branches, which are forked off the main/feature branches. After a while when POC is complete, we/the dev no longer uses it.
Now over time the no of such POC branches increase and the repo doesnt look good.
So during our periodic maintenance and cleaning of GIT repo, we delete all such POC branches.

How to sync your local branch list.
Simple:

[parag@paragpc: ~/ProjectCodeName] git fetch -p

 x [deleted]   (none)  ->origin/POC-webCache

 x [deleted]   (none)  ->origin/POC-CDNChange

[parag@paragpc: ~/ProjectCodeName] 

where -p = --prune
                     After fetching, remove any remote-tracking branches which no longer exist on the remote. 


Similarly, if you are have created a local branch and committed some changes while the remote tracking branch is not present at origin, issue:

[parag@paragpc: ~/GitProject] git branch -d <the_dirty_poc_branch>

where -d = --delete
        Delete a branch. The branch must be fully merged in its upstream branch, or in HEAD if no upstream was set with --track or --set-upstream

PS: Before running any delete related operation on branch its better to double check and understand what you are doing!.

Clean untracked files in GIT repo

Sometimes you add some files/directory to your (local cloned) git repo directory. May be because you need them for testing or they are additional files required for reference
and it does not makes sense to add a particular directory/path in your .gitignore file. But then you want to clean those files.

git reset --hard HEAD ./<folder>

[parag@machine: Workdir] git reset --hard HEAD ./<foler>

does not work, as it does not clean with specific paths. You can do it via:

[parag@machine: Workdir] git clean -d -f
