Navigating the file system using the command line.
Current Working Directory
The 'pwd' command prints the current working directory.
pwd
In your case it will show /home/{your-username}
List Current files and Directory
The 'ls" command lists the files and directories in the current directory.
ls
"ls -a" will list all the files and directories present in the current directory including hidden files.
ls -a
(The names beginning with '.' are hidden files and directories)
"ls -l" will list the files and directories present in the current directory in a list view giving details such as
ls -l
The task for you is to think what "ls -al" command will do.
Change Directory
The 'cd' command allows you to change the current directory to a new directory.
cd /Desktop
"cd " will take you to your current users home directory(which is /home/abhi in my case).
cd
"cd .." will take you to your parent directory. The directory that the current directory is inside of. (here ".." signifies the parent directory)
cd ..
