When illustrating the contents of a file or a fragment from a file a different font is used. The following example demonstrates this:
#!/bin/bash # A simple script echo "Hello, world!"
At various points, the output seen in a terminal session is given. This, too, uses a different font and has a slightly different appearance to a file contents. For example:
paul@pythia:~$ chmod 755 hello-world.sh paul@pythia:~$ ./hello-world.sh Hello, world!
