Navigate and quote paths

Navigate and quote paths — guided practice

Use relative paths and quote a folder name containing spaces.

Create an empty shell-lab folder. Inside it create input and output folders. Put registrations.tsv in input with these tab-separated rows and a final newline: session<TAB>status; art<TAB>confirmed; code<TAB>confirmed; art<TAB>waiting; code<TAB>confirmed; music<TAB>confirmed. Start the terminal in shell-lab. Bash required; no sudo, remote systems or deletion commands. Start from shell-lab; existing files remain unchanged.

1. 1. Enter input

   Run cd input, then pwd.

   cd input
   pwd

   You should see: The final component changes to input.

   cd changes the shell’s current location.

2. 2. Read the parent path

   Run ls ../output.

   ls ../output

   You should see: The empty output folder prints no names.

   Two dots mean the parent folder, not a filename wildcard.

3. 3. Return

   Run cd .. and verify pwd.

   cd ..
   pwd

   You should see: You are back in shell-lab.

   Returning before the next command keeps paths predictable.

4. 4. Create a quoted folder

   Run mkdir "review notes", then ls.

   mkdir "review notes"
   ls

   You should see: A single folder named review notes appears.

   Quotes prevent the space from splitting two arguments.
