The person who associated a work with this deed has dedicated the work to the public domain by waiving all of his or her rights to the work worldwide under copyright law, including all related and neighboring rights, to the extent allowed by law.

You can copy, modify, distribute and perform the work, even for commercial purposes, all without asking permission.

Statement of Purpose

The laws of most jurisdictions throughout the world automatically confer exclusive Copyright and Related Rights (defined below) upon the creator and subsequent owner(s) (each and all, an "owner") of an original work of authorship and/or a database (each, a "Work").

Certain owners wish to permanently relinquish those rights to a Work for the purpose of contributing to a commons of creative, cultural and scientific works ("Commons") that the public can reliably and without fear of later claims of infringement build upon, modify, incorporate in other works, reuse and redistribute as freely as possible in any form whatsoever and for any purposes, including without limitation commercial purposes. These owners may contribute to the Commons to promote the ideal of a free culture and the further production of creative, cultural and scientific works, or to gain reputation or greater distribution for their Work in part through the use and efforts of others.

For these and/or other purposes and motivations, and without any expectation of additional consideration or compensation, the person associating CC0 with a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and publicly distribute the Work under its terms, with knowledge of his or her Copyright and Related Rights in the Work and the meaning and intended legal effect of CC0 on those rights.

1. Copyright and Related Rights. A Work made available under CC0 may be protected by copyright and related or neighboring rights ("Copyright and Related Rights"). Copyright and Related Rights include, but are not limited to, the following:

   the right to reproduce, adapt, distribute, perform, display, communicate, and translate a Work;
   moral rights retained by the original author(s) and/or performer(s);
   publicity and privacy rights pertaining to a person's image or likeness depicted in a Work;
   rights protecting against unfair competition in regards to a Work, subject to the limitations in paragraph 4(a), below;
   rights protecting the extraction, dissemination, use and reuse of data in a Work;
   database rights (such as those arising under Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, and under any national implementation thereof, including any amended or successor version of such directive); and
   other similar, equivalent or corresponding rights throughout the world based on applicable law or treaty, and any national implementations thereof.

2. Waiver. To the greatest extent permitted by, but not in contravention of, applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and unconditionally waives, abandons, and surrenders all of Affirmer's Copyright and Related Rights and associated claims and causes of action, whether now known or unknown (including existing as well as future claims and causes of action), in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each member of the public at large and to the detriment of Affirmer's heirs and successors, fully intending that such Waiver shall not be subject to revocation, rescission, cancellation, termination, or any other legal or equitable action to disrupt the quiet enjoyment of the Work by the public as contemplated by Affirmer's express Statement of Purpose.

3. Public License Fallback. Should any part of the Waiver for any reason be judged legally invalid or ineffective under applicable law, then the Waiver shall be preserved to the maximum extent permitted taking into account Affirmer's express Statement of Purpose. In addition, to the extent the Waiver is so judged Affirmer hereby grants to each affected person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and unconditional license to exercise Affirmer's Copyright and Related Rights in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "License"). The License shall be deemed effective as of the date CC0 was applied by Affirmer to the Work. Should any part of the License for any reason be judged legally invalid or ineffective under applicable law, such partial invalidity or ineffectiveness shall not invalidate the remainder of the License, and in such case Affirmer hereby affirms that he or she will not (i) exercise any of his or her remaining Copyright and Related Rights in the Work or (ii) assert any associated claims and causes of action with respect to the Work, in either case contrary to Affirmer's express Statement of Purpose.

4. Limitations and Disclaimers.

   No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.
   Affirmer offers the Work as-is and makes no representations or warranties of any kind concerning the Work, express, implied, statutory or otherwise, including without limitation warranties of title, merchantability, fitness for a particular purpose, non infringement, or the absence of latent or other defects, accuracy, or the present or absence of errors, whether or not discoverable, all to the greatest extent permissible under applicable law.
   Affirmer disclaims responsibility for clearing rights of other persons that may apply to the Work or any use thereof, including without limitation any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims responsibility for obtaining any necessary consents, permissions or other rights required for any use of the Work.
   Affirmer understands and acknowledges that Creative Commons is not a party to this document and has no duty or obligation with respect to this CC0 or use of the Work.

Nano Ubuntu

Getting Started

To start using Nano on Ubuntu 22.04, follow these steps:

Open your terminal or command prompt.
Type nano followed by the name of the file you want to edit. For example, to edit a file called myfile.txt, type nano myfile.txt.
Once Nano opens, you will see the contents of the file you are editing.

Navigating the File

Nano uses keyboard shortcuts for navigation. Here are some essential navigation commands:

Ctrl+F - Move forward one character
Ctrl+B - Move backward one character
Ctrl+N - Move to the next line
Ctrl+P - Move to the previous line
Ctrl+A - Move to the beginning of the current line
Ctrl+E - Move to the end of the current line
Ctrl+V - Move forward one page
Ctrl+Y - Move backward one page

Editing Text

Here are the commands for editing text in Nano:

Ctrl+K - Cut the current line or selected text
Ctrl+U - Uncut (paste) the last cut text
Ctrl+Shift+6 - Mark the beginning of a selection
Ctrl+Shift+7 - Mark the end of a selection
Ctrl+T - Transpose two characters
Ctrl+O - Save the changes to the file
Ctrl+X - Exit Nano without saving the changes

Wipe Entire File:

To wipe the entire content of a file in Nano:

Move the cursor to the beginning of the file by pressing Ctrl+Y repeatedly until you reach the top.
Press Ctrl+Shift+6 to set the beginning of the selection.
Move the cursor to the end of the file by pressing Ctrl+V repeatedly until you reach the end.
Press Ctrl+K to cut the selected text.
To paste the cut text elsewhere, move the cursor to the desired location and press Ctrl+U.

Alternatively, you can use the terminal command > /path/to/file.txt to wipe the file's contents. However, use this with caution as it can easily overwrite the wrong file.

Transpose:

The Ctrl+T command is used to transpose (swap) the characters at the current cursor position with the characters immediately before the cursor position.

To use Ctrl+T:

Move the cursor to the position between two characters you want to swap.
Press Ctrl+T.
The two characters will be swapped, and the cursor will move to the right by one character.

For example:

This is a test.
     ^ Cursor is here

To swap "s" and "i" in "is":

Move the cursor between "s" and "i":

This is a test.
      ^ Cursor is here

Press Ctrl+T.

The characters "s" and "i" will be swapped:

This si a test.
      ^ Cursor moves here

Searching for Text

To search for text in Nano:

Ctrl+W - Search for a word or phrase in the current file
Alt+W - Repeat the last search

Replacing Text

To replace text in Nano:

Alt+R - Replace the current occurrence of a search term

Other Useful Commands

Ctrl+G - Display the Nano help menu
Ctrl+_ - Go to a specific line and column number
Ctrl+Y - Move backward one page
Ctrl+V - Move forward one page

Note: To scroll line by line, use the arrow keys or Ctrl+P (previous line) and Ctrl+N (next line).

Note: Nano does not have built-in commands to increase or decrease text size. To adjust text size, use your terminal emulator's settings or shortcuts. For example, in GNOME Terminal, use Ctrl+Shift+'+' to increase and Ctrl+'-' to decrease text size.
