Coder’s Computer Notes

A text editor is a piece of software that you download and install on your computer, or you access online through your web browser, that allows you to write and manage text, especially the text that you write to build a web site.

Syntax highlighting is a feature that takes the text > you type, and makes it more noticeable by colorizing the text. Usually, web developers use a dark background and brightly colored text. This combination seems to be easier on the eyes but there are other themes to choose from as well.

What other software can you use to edit?

  • Notepad++
  • Text Wrangler
  • BB Edit
  • Visual Studio Code
  • Atom
  • Brackets
  • Sublime Text

Some of these softwore are free and some will have to purchase

Cheat Sheet

  • pwd is Print Working Directory..Where are we currently.
  • ls means List the contents of a directory.
  • cd is Change Directories…move to another directory.
  • file is obtain information about what type of file a file or directory is.
  • ls -a is List the contents of a directory, including hidden files.
  • tilde is a shortcut for your home directory. eg, if your home directory is /home/ryan then you could refer to the directory Documents with the path /home/ryan/Documents or ~/Documents
  • dot is a reference to your current directory. eg in the example above we referred to Documents on line 4 with a relative path. It could also be written as ./Documents (Normally this extra bit is not required but in later sections we will see where it comes in handy).

  • dotdot is a reference to the parent directory. You can use this several times in a path to keep going up the hierarchy. eg if you were in the path /home/ryan you could run the command ls ../../ and this would do a listing of the root directory.

  • Relative path A file or directory location relative to where we currently are in the file system.
  • Absolute path A file or directory location in relation to the root of the file system.

Important to Remember

  • Everything is a file under Linux

Even directories

  • Linux is an extensionless system

Files can have any extension they like or none at all

  • Linux is case sensitive

Beware of silly typos
