Deleting a file or folder from git uses the rm command.

  • Delete the folder locally and remotely.
git rm dist
git commit -m "Removing distribution files from repo."
  • Delete the folder ONLY from the remote branch:
git rm --cached dist
git commit -m "Removing distribution files from repo."


StackOverflow saves the day again:




This is a great article on the Git Branching Model.

Basically, all development work should be done on a separate branch off the master, which we would call “develop”. Any features would be branches off develop and merged back to develop once tested and complete.

Atlassian also describes several Git models, with the branching model also explained:



Deleting a remote branch seems is easy.

  • First, delete the branch locally.
git branch -d feature-to-delete
  • Next, delete the branch remotely by “pushing” the deletion.
git push origin --delete feature-to-delete
git push origin :feature-to-delete

Note that doing a push to delete a remote branch deletes the remote-tracking branch (there are actually 3 branches when a local branch has a remote), so no pruning is necessary.

Pretty easy right!

Things to note: the -d will give you a warning if the branch has not yet been merged. The -D option will do a force deletion and you may lose your un-merged changes.


This StackOverflow article has a lot of good answers:




When searching for records that fall within a certain date, using a timestamp, you may want to look at these queries:

// From

db.posts.find( //query today up to tonight
  {"created_on": {"$gte": new Date(2012, 7, 14), "$lt": new Date(2012, 7, 15)}})

Another way to do this:

var start = new Date(2010, 11, 1);
var end = new Date(2010, 11, 30);

db.posts.find({created_on: {$gte: start, $lt: end}});
//taken from

If searching against the ObjectID timestamp, use this query:

> var objIdMin = ObjectId(Math.floor((new Date('1990/10/10'))/1000).toString(16) + "000
> var objIdMax = ObjectId(Math.floor((new Date('2011/10/10'))/1000).toString(16) + "000
> db.myCollection.find({_id:{$gt: objIdMin, $lt: objIdMax}})

// From

Querying using the Mongo Timestamp object:

  created_at : {
      '$gte': new Timestamp(new Date(2012, 0, 21), 0), 
      '$lte': new Timestamp(new Date(2012, 0, 22), 0)

// From GIST


When performing find() queries in the Mongo shell, you may have noticed you get a maximum of 20 rows before having to request the next records with the “it” command.

This can be configured!

From, enter this line of code in the shell

DBQuery.shellBatchSize = 100;

This will allow you to display up to 100 records at a time when performing queries in the shell. You can configure this at any time to get more or less records in the command line.

If you’re like me, you may have added one too many files to your git repository on a late night of coding… You don’t want to delete the files locally, so you can’t just delete the files and commit. Read More »
