Chapter 1: Introduction to the Command Line

Activity 1: Navigating the Filesystem and Viewing Files

1. Use the cd command to navigate to the appropriate folder and use less to read the relevant information:

   robin ~ $ cd Lesson1/data
   robin ~/Lesson1/data $ cd pinaceae/cedrus/deodara/
   robin ~/Lesson1/data/pinaceae/cedrus/deodara $ less data.txt

2. Use the cd command to navigate the appropriate folder and view the file with less. Use the / command to search for the phrase "derives from" and read the rest of the sentence to get the answer:

   robin ~/Lesson1/data/pinaceae/cedrus/deodara $ cd ../../..
   robin ~/Lesson1/data $ cd pinaceae/abies/pindrow/
   robin ~/Lesson1/data/pinaceae/abies/pindrow $ less data.txt

3. Navigate to the right folder and run the tree command, which reports the number of directories in it. Each directory is a species:

   robin ~/Lesson1/data/pinaceae/abies/pindrow $ cd ../../..
   robin ~/Lesson1/data $ cd taxaceae/taxus/
   robin ~/Lesson1/data/taxaceae/taxus ...
