DIRECTORY STRUCTURE

mkdir | // creates new folder within directory

mkdir -p directory\ level_1/level_2/level_3 // creates a directory structure

mkdir -p zeta ia lury // creates 3 directories

mkdir mkdir -p zeta/zeta_level_1 ia/ia_level_1 lury/lury_level_1 // adds folder to directory structure

ls -R // shows directory structure in levels

rmdir // removes a directory // if directory is not empty the entire path requires specification

directory structure a/b/c/d/e // e is referred as the directory at the top

rmdir a/b/d/d/e // removes directory e only

rmdir -p a/b/d/d/e // removes entire directory

rmdir -pv a/b/d/d/e // removes entire directory with step description // directory documents require specification

rm // removes folder and documents inside without specification

rm -r // removes directory from Parent directory

rm - r -rv // recursive step verbose removal of directory

cp text_0.txt text_3.txt // copies document text to new document

Material Irreversibilities to Human Life|Time

The Quantifiable Divisorial Illustrative to the Problem of the Act over the Knowledge

The Reliance over the Loss of [ ]

Materially Observing the Universe to Understand a Problem to Engineer a Solution

The Production of Information to Satisfy a Person Want to a Limit of one Day over the Limit of Solving any Productivity Problem termed Scientific > The Results on Observation to the Illustration of Fundamental Problems with and without the Understanding of The People to First Identify the Problem.

The Structure of the Computer is Result to Solving a Material Problem that any calculation is balanced with a Human.

The Limit to Knowledge resides within Scientific Information that the collection of corruptible information over the time that the Digital Computer has existed is Catastrophic over the denial of the existence of information without the result of eliminating the root causes of the problems themselves that a person creating a law would interpret reality without knowledge is catastrophic. The results of information to perpetuate a form of acceptability of irreversibilities to the climate and the economy remain the persistent problem to solve. The results on what remains irreversible are and have been presently knowable so the Humans will in a form utilize technology to honor their resposibility to the Planet.

Think about how you interact with your environment to Infinity.

Thinking in the ability of what is quantifiable exists to the use of obtained information to the limit of how the information is actionable to produce an immediate result > The Action is Executed with the Available Information[X]

When no new information exists to create a solution and new information is required the sources of the new information are considered and the process of how the new information is obtained. In Computer Science the process of creating solutions requires Human Collaboration just like in Architecture Engineering Every Science. After +100 years of this era of digital computer use the problem of Collaboration persists to the gravest of forms to the redundancy over the loss of Total Collaboration outside of the problem of Collaboration that existed in Social Development before the prevalent use of computers at any time in the 20th century. In one day the Total Activity of a Human is metric that the knowledge of any problem that does not result in new scientific development is determinable in ways that do not require computation that the use of the computer has resulted in a Communication Problem tied to the use of technology not exclusively. The examples of how technology results in less communication are rooted in how the human decides to use the technology and not the technology itself grave to the progress of technology as any improvement that human communication and decision making will reach a normal level of acceptability from the acceptance of social uses of technology from thoughts that a generation looses the core behavior of previous generations. The functionality of any technology progresses without the total knowledge of the development of the technology so technological development does not erase how technology is approached.
