Is there an easy or "how to" way in understanding the commands used in the CLI?

[sharee]

I am having a hard time understanding how to order the commands in the CLI. Its like I don't have a clue as to what do next.
I get to a certain point and stop.

Hi and Welcome !

I would suggest you to check linuxcommand.org first. Follow its tutorials and you will have enough knowledge to work in CLI. There are a lot of another websites on Linux commands and scripting but linuxcommand.org is best place to start, imho.

Another good resource is to use man pages. man pages (short for "manual") are essentially the documentation for a given command.

For instance, if you learn about using the command "grep" to solve a specific problem, you can run the command "man grep" to learn even more about grep and all of its features.

This way, you can also expand your knowledge of commands on your own.

You may also want to look into the command "man -k WORD", which looks for commands that contain WORD in their description. So if you want to replace text in a file, you might run:

alex@danu:~$ man -k replace
argz_replace (3)     - functions to handle an argz list
ExtUtils::Command (3perl) - utilities to replace common UNIX commands in Make...
Fatal (3perl)        - replace functions with equivalents which succeed or die
perlclib (1)         - Internal replacements for standard C library functions
pkfix (1)            - replace pk fonts in postscript files with type1 versions
replace (1)          - a string-replacement utility
run-with-aspell (1)  - script to help use GNU Aspell as an ispell replacement
ssh-argv0 (1)        - replaces the old ssh command-name as hostname handling
XkbGetKeyboardByName (3) - Build a new keyboard description from a set of nam...

And now you can check, for instance, the man page for "replace" to see if it does what you want.
