Navigating through the folder structure in Linux is easy if you know a few commands. A major issue for many technicians is that Linux cares about capitalization (FOLDER != folder), and using / with the cd command causes Linux to look for the folder in the System Root.

Notes

Capitalization matters in navigation. “FOLDER” is different than “Folder”. You can have 4 separate folders named: FOLDER, Folder, folder, foldeR.
when using cd to go into a lower level folder DO NOT use /. If you are in the “home” folder and want to go into the “bob” folder you would type “cd bob” NOT “cd /bob”
Find Where You Are

The “pwd” command tells you your location in the folder structure

Changing Directories

The basic command to change directories is “cd”.
“cd ..” moves you up one folder level.
“/” represents the system root.
From the “home” folder you could use “cd” like this:
cd ..
cd bob
cd /
cd /home/bob
Listing Folder Contents with “ls”

“ls” lists the contents of a folder
“ls -l” lists contents of a folder and displays ownership and permissions
“ls -lh” is the same as “ls -l” but formats the file sizes to be easier to read.
