Just Saying Hi from kb5zxm aka Darrell Derrick Magnolia Texas

Hello darrell derrick,

Welcome to Linux Lite and the forum 

When using the terminal cli these are a few of the first commands I have learned relating to navigating.

Code:

--help

type the command name a space and then --help will show a description of the command.
example

Code:

ls --help

Code:

man

man or manual pages display the manual about a command or program, you type man then a space and the command for example man ls will show the manual pages for the ls command.

Code:

info

then the command name, like man pages but it can have more detailed, if unavailable it will default to the man page usually it seems.
Try

Code:

man ls

then try

Code:

info ls

as an example comparison.

Code:

pwd

present working directory

Code:

ls

lists the contents of the current directory

Code:

ls -R

lists recursively , shows the contents of the directory and the contents of the folders in the directory.

Code:

ls -a

lists the directory contents and lists the hidden files in the directory.

Code:

ls -aR

lists the directory contents and the contents of all folders , and all the hidden files.

Code:

cd

cd a space and then the Directory name, (case sensitive directory names) will change to that directory as the pwd.
Example

Code:

cd Music

Code:

cd ~

cd and a tilde, used in any directory will change your pwd to your Home directory, for your username.
It's a really great command, and helped me/gave me a bit more confidence not to get lost whilst navigating.

Code:

cd ..

will move you up /back the directory structure by 1 level.

Code:

ls -l

will list the files and give more information about them, such as permissions, file size, dates. Long file format.

Code:

cal

was one of the first commands I used , and I like it, it displays a useful calendar with current date highlighted.

Code:

free

displays system stats, initially I used this and the above command to get used to cli.

Then added

Code:

clear

which clears the cli window other than the prompt.

Code:

exit

to close the cli for the session/day

I think these are the only ones I know so far that I've practiced.
Most important I found is to just relax and have fun with learning.
