To wipe a file in terminal you can also use <code>> /path/to/file.txt</code> to wipe the file.
Alternatively, you can use the terminal command <code>> /path/to/file.txt</code> to wipe the file's contents. However, use this with caution as it can easily overwrite the wrong file.
* The '''>''' operator is used to redirect standard output to a file. If the file doesn't exist, it will be created; if it does exist, it will be overwritten.
* So, this command would effectively create an empty file at '''/path/to/file.txt''' if the file doesn't exist, or clear the contents of the file if it already exists.
* Be Careful when using this, as it becomes easier to nuke the wrong file.

Here's how to use the '''Ctrl+T''' command:
 
:    Move the cursor to the position between two characters that you want to swap.

For example, let's say you have the following line of text in Nano:
For example:


<pre>
<pre>
Line 74: Line 67:
</pre>
</pre>


If you want to swap the characters "s" and "i" in the word "is", you would do the following:
To swap "s" and "i" in "is":


:    Move the cursor to the position between the "s" and the "i", like this:
# Move the cursor between "s" and "i":


<pre>
<pre>
Line 83: Line 76:
</pre>
</pre>


:    Press '''Ctrl+T'''.
# Press <code>Ctrl+T</code>.
:    The characters "s" and "i" will be swapped, like this:
 
# The characters "s" and "i" will be swapped:


<pre>

       ^ Cursor moves here
       ^ Cursor moves here
