NAME ls - list directory contents SYNOPSIS ls [OPTION]... [FILE]... DESCRIPTION List information about the FILEs (the current directory by de‐ fault). Sort entries alphabetically if none of -cftuvSUX nor --sort is specified. Mandatory arguments to long options are mandatory for short options too. -a, --all do not ignore entries starting with . -A, --almost-all do not list implied . and .. --author with -l, print the author of each file -b, --escape print C-style escapes for nongraphic characters --block-size=SIZE with -l, scale sizes by SIZE when printing them; e.g., '--block-size=M'; see SIZE format below -B, --ignore-backups do not list implied entries ending with ~ -c with -lt: sort by, and show, ctime (time of last modifica‐ tion of file status information); with -l: show ctime and sort by name; otherwise: sort by ctime, newest first -C list entries by columns --color[=WHEN] colorize the output; WHEN can be 'always' (default if omit‐ ted), 'auto', or 'never'; more info below -d, --directory list directories themselves, not their contents -D, --dired generate output designed for Emacs' dired mode -f do not sort, enable -aU, disable -ls --color -F, --classify append indicator (one of */=>@|) to entries --file-type likewise, except do not append '*' --format=WORD across -x, commas -m, horizontal -x, long -l, single-column -1, verbose -l, vertical -C --full-time like -l --time-style=full-iso -g like -l, but do not list owner --group-directories-first group directories before files; can be augmented with a --sort option, but any use of --sort=none (-U) disables grouping -G, --no-group in a long listing, don't print group names -h, --human-readable with -l and -s, print sizes like 1K 234M 2G etc. --si likewise, but use powers of 1000 not 1024 -H, --dereference-command-line follow symbolic links listed on the command line --dereference-command-line-symlink-to-dir follow each command line symbolic link that points to a directory --hide=PATTERN do not list implied entries matching shell PATTERN (overrid‐ den by -a or -A) --hyperlink[=WHEN] hyperlink file names; WHEN can be 'always' (default if omit‐ ted), 'auto', or 'never' --indicator-style=WORD append indicator with style WORD to entry names: none (de‐ fault), slash (-p), file-type (--file-type), classify (-F) -i, --inode print the index number of each file -I, --ignore=PATTERN do not list implied entries matching shell PATTERN -k, --kibibytes default to 1024-byte blocks for disk usage; used only with -s and per directory totals -l use a long listing format -L, --dereference when showing file information for a symbolic link, show in‐ formation for the file the link references rather than for the link itself -m fill width with a comma separated list of entries -n, --numeric-uid-gid like -l, but list numeric user and group IDs -N, --literal print entry names without quoting -o like -l, but do not list group information -p, --indicator-style=slash append / indicator to directories -q, --hide-control-chars print ? instead of nongraphic characters --show-control-chars show nongraphic characters as-is (the default, unless pro‐ gram is 'ls' and output is a terminal) -Q, --quote-name enclose entry names in double quotes --quoting-style=WORD use quoting style WORD for entry names: literal, locale, shell, shell-always, shell-escape, shell-escape-always, c, escape (overrides QUOTING_STYLE environment variable) -r, --reverse reverse order while sorting -R, --recursive list subdirectories recursively -s, --size print the allocated size of each file, in blocks -S sort by file size, largest first --sort=WORD sort by WORD instead of name: none (-U), size (-S), time (-t), version (-v), extension (-X) --time=WORD change the default of using modification times; access time (-u): atime, access, use; change time (-c): ctime, status; birth time: birth, creation; with -l, WORD determines which time to show; with --sort=time, sort by WORD (newest first) --time-style=TIME_STYLE time/date format with -l; see TIME_STYLE below -t sort by time, newest first; see --time -T, --tabsize=COLS assume tab stops at each COLS instead of 8 -u with -lt: sort by, and show, access time; with -l: show ac‐ cess time and sort by name; otherwise: sort by access time, newest first -U do not sort; list entries in directory order -v natural sort of (version) numbers within text -w, --width=COLS set output width to COLS. 0 means no limit -x list entries by lines instead of by columns -X sort alphabetically by entry extension -Z, --context print any security context of each file -1 list one file per line. Avoid '\n' with -q or -b --help display this help and exit --version 2 if serious trouble (e.g., cannot access command-line argu‐ ment). AUTHOR Written by Richard M. Stallman and David MacKenzie.

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.
