PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Overview

Here you will find instructions for importing the datasets for M001: MongoDB Basics into a locally running MongoDB deployment.

Datasets

All datasets are provided in Amazon S3 in a single zip file (243 MB zipped; 1.5 GB unzipped). The files were created with the mongodump command. They may be imported into your MongoDB deployment using mongorestore. Note that these datasets include the indexes necessary to support example queries and labs used in M001. The datasets included are as follows.

object Solution {
    def solution(N: Int): Int = {
      if (N < 1) sys.error(s"Invalid input: $N")

      @scala.annotation.tailrec
      def foo(i: Int, total: Int): (Int, Int) = {
        if ((i * i) >= N) (total, i)
        else if (N % i == 0) foo(i + 1, total + 2)
        else foo(i + 1, total)
      }

Add user to group and make sudoer/nopassword-access

Ubuntu

• adduser username
• usermod -aG groupname username or gpasswd -a user_name group_name
  • usermod -aG sudo username
• visudo
  • username ALL=(ALL) NOPASSWD:ALL
• Remove a user from a group

royki

To copy using scp and no password

• create a folder of own user and become the owner of that folder by chown: folder_name

copy over ssh using scp

• scp gitlabhq_stag.backup royki@gitlab127.0.0.1.net:/gitlab-data/dump

Copy a Local File to a Remote System with the scp Command

• scp file.txt royki@10.10.0.2:/remote/directory
• If SSH on the remote host is listening on a port other than the default 22 then you can specify the port using the -P argument:
  • scp -P 2322 file.txt royki@10.10.0.2:/remote/directory
