Examine a Script with Syntax Highlighting in the Editor

Navigate into the cellar and select treasure to view it in the code editor.
At the top of the script is a shebang statement: #!/bin/bash
- The shebang statement tells the system to use bash to interpret the commands in this script file.
- The editor uses that same statement to perform syntax highlighting. That is, it colors the statements in the script based on its knowledge of bash.
The exact coloring can be set by changing the theme (File → Preferences → Color theme), but the default used here is:

heredoc

A heredoc is a special block of code that behaves as a separate code block. The heredocs in bashcrawl are delimited by EOF (end of file). A heredoc is often used to echo text to the screen as it is less cumbersome for a big block than using echo "blah blah" at the beginning of each line.
