![]() Inside this window, you can see the Database tab. Unfortunately, the way the system processes the shebang line, everything after the first space is passed as a single parameter (as if quoted) to the env command, and env fails to find and run it. Step 1 Preparing the Sample Database To explain how to create queries in MongoDB including how to filter documents with multiple fields, nested documents, and arrays this guide uses an example database containing a collection of documents that describe the five highest mountains in the world. When you are connected to the MongoDB Atlas or Mongo Shell, the following window will appear. I have tried adding the database name to the shebang, which you would think would work. It functions exactly like "mongo " which means it does not let you use the "use " command. And all you save by doing so is not having to type "mongo" on the command line. You can't mix regular shell commands with mongo shell commands. It only works if you are trying to make a mongo shell script executable from the command line. The MongoDB shell enables you to connect to the database from a command line prompt and interactively work with it from a terminal window. There are several problems with this solution: The MongoDB shell is an interactive console you can use to connect to the database server and execute commands on it, allowing you to perform administrative tasks and read, write, or manipulate data directly. The down side: That doesn't work if you need to put shell parameters/variables in your mongo script.Īnother option you can play with is to mess with your shebang. Now, you can put all the dollar signs you want in your heredoc, and the dollar signs are ignored. The other option is to escape the EOF, like this: #!/usr/bin/sh I do NOT recommend this, because it is easy to forget to escape. ![]() First, the ugly one: escape the $ signs: #!/usr/bin/sh In order to have it pass through you have two options. The above will NOT work, because the phrase "$exists" will be seen by the shell and substituted with the value of the environment variable named "exists." Which, likely, doesn't exist, so after shell expansion, it becomes: #!/usr/bin/sh I use the "heredoc" syntax, which David Young mentions.
