Nano syntax highlighting malformed regex?
In general, you could do the "divide and conquer" route. Make a
copy of the file. Remove half, try the config. If the syntax has
an error, it's in the half that's in the file - repeat (remove
half). If not, it's in the half that you deleted. Use the half
that you split out, and remove half from that, until you get to
one line that's bad.
I don't know the file format, but my guess would be the line
#color red ""(\\.|[^\"])*""
It starts with ", then a " right away, closing it, then regex in
between. Im guessing you need to escape the inner quotes:
#color red "\"(\\.|[^\"])*\""

Open a Console Based Editor with limited access
Not exactly what you're looking for, but rvim does some
of what you want. Perhaps it's possible to do some tricks with
chroot. I don't know.
It will not be possible to start shell commands, or suspend
Vim.

An esay way to empty a config file in Linux?
cat /dev/null > file.txt
Executing this command will make the file blank.

Missing the first character of a line on full screen apps on Linux server ssh'ed from OS X Terminal
The problem you describe is typical of an incorrect value for the
TERM environment variable. Specifically, the value of the TERM
variable on Ubuntu selects a set of terminal features and
capabilities that do not match those of the OS X Terminal
application.
If TERM is set to something like xterm-color or
xterm-256color try setting it to other values (e.g.
the other one from the two I mentioned, or plain
xterm, ansi or vt220).
UPDATE:
In OS X Terminal.app, try the following commands
TERM=ansi nano googlef916dafa821844e0.html
TERM=vt220 nano googlef916dafa821844e0.html
TERM=xterm nano googlef916dafa821844e0.html
TERM=xterm-color nano googlef916dafa821844e0.html
TERM=xterm-256color nano googlef916dafa821844e0.html

Find next command in nano?
You can get a list of all keyboard shortcuts by pressing
^G (Ctrl + G).
From Main nano help text:
M-W (F16) Repeat last search
M-W is Vim/Emacs notation, where M means
Meta (a key present on MIT and Sun keyboards).
On IBM-compatible keyboards – depending on, e.g., your window
manager and terminal emulator – you can invoke the shortcut with
Alt + W (hold, tap), Win +
W (hold, tap) or Esc, W (tap,
tap).
In the unlikely case your keyboard has such a key, you can simply
press F16.

Is it possible to remove the $ from nano in linux on longlines?
Yes this is possible. I no longer have nano installed so I can't
lookup how. But you'll find the setting by doing either man
nano or man nanorc.

Copying from one file to another using nano editor
Assuming you are in pure console mode and can't use the mouse to
copy/paste:
- Launch nano in multi-buffer mode (nano -E)
- CTRL-^ to start your selection.
- Arrow key around until you cover all the text you want to
copy.
- ESC-^ to copy the selection into the cut buffer
- CTRL-R ESC-F to open a file into a new buffer
- CTRL-U to paste in the opened file
NOTE: To switch between buffers use ESC-< and ESC->
An alternative to 2-4 above is to go to the line(s) you want to
copy and CTRL-K to delete them, pressing CTRL-K repeatedly to
multiple lines to the buffer. When you've cut all the lines you
want to copy, CTRL-Y to re-paste them back into the current
buffer. Then continue with step 5.

Nano-like editor that support Ctrl+Backspace and Ctrl+Arrow keys
I'm not sure if it's available in your environment, but a useful
piece of software for the terminal is Midnight
Commander (their site uses a self-signed certificate, so
don't worry about this). It has a built-in editor with a lot of
shortcuts, syntax highlighting, etc. and its behaviour is
like in Windows.
source
Is there a way to make Nano support auto-complete and auto-bracket closing?
I just downloaded and perused the source of Nano with some
grepping. I can say with 95% confidence that Nano doesn't support
auto-bracket or auto-complete.
Meta-] will jump to the matching bracket under the cursor though.
Sorry!
source
Making nano accepting previous piped output as a file path
Nano behaves like expected, since a pipe is used to connect on
program's output to another one's input.
What you want instead is to use the output of find
as an argument for nano:
nano `find / -iname httpd.conf`
source
Nano usablely open second file
No, it's not possible. That's what advanced editors (Emacs, Vim,
kate gedit, you name it) are for.
However, it is possible to do something useful, even though more
restricted: you can add files to the one you are working on, and
you can do so in a moderately effective way. When you say Read
(or Write!) file, you may give the command ^T which will open a
graphical window, and you can search for the file by moving
within this graphical windows as if you were inside Nautilus or
Dolphin, or whatever. Alternatively, again after invoking the
Read or Write commands, you may issue commands to the shell by
means of ^X.

Print feature in nano?
I can see no mention of a print command in nano's
manual and it would surprise me to find one. The traditional
method of printing in *nix systems is the lpr
command:
$ lpr foo.txt
From man lpr:
DESCRIPTION
lpr submits files for printing. Files named on the command line are
sent to the named printer (or the default destination if no destination
is specified). If no files are listed on the command-line, lpr reads
the print file from the standard input.
You can also use a slightly more modern equivalent,
enscript:
DESCRIPTION
Enscript converts text files to PostScript or to other output lan?
guages. Enscript can spool the generated output directly to a speci?
fied printer or leave it to a file. If no input files are given,
enscript processes the standard input stdin. Enscript can be extended
to handle different output media and it has many options which can be
used to customize the printouts.

How to save module configuration in Linux Terminal
In nano use "WriteOut" (CtrlO) to save the
file.
description
This manual
page briefly documents the nano command.
nano is
a small, free and friendly editor which aims to replace
Pico, the default editor included in the non-free Pine
package. Rather than just copying Pico’s look and
feel, nano also implements some missing (or disabled
by default) features in Pico, such as "search and
replace" and "go to line and column
number".
options
+LINE,COLUMN
Places cursor at line number
LINE and column number COLUMN (at least one of
which must be specified) on startup, instead of the default
of line 1, column 1.
-A
(--smarthome)
Make the Home key smarter. When
Home is pressed anywhere but at the very beginning of
non-whitespace characters on a line, the cursor will jump to
that beginning (either forwards or backwards). If the cursor
is already at that position, it will jump to the true
beginning of the line.
-B
(--backup)
When saving a file, back up the
previous version of it to the current filename suffixed with
a ~.
-C dir
(--backupdir=dir)
Set the directory where
nano puts unique backup files if file backups are
enabled.
-D
(--boldtext)
Use bold text instead of
reverse video text.
-E
(--tabstospaces)
Convert typed tabs to
spaces.
-F
(--multibuffer)
Enable multiple file buffers,
if available.
-H
(--historylog)
Log search and replace strings
to ~/.nano_history, so they can be retrieved in later
sessions, if nanorc support is available.
-I
(--ignorercfiles)
Don’t look at
SYSCONFDIR/nanorc or ~/.nanorc, if
nanorc support is available.
-K
(--rebindkeypad)
Interpret the numeric keypad
keys so that they all work properly. You should only need to
use this option if they don’t, as mouse support
won’t work properly with this option enabled.
-L
(--nonewlines)
Don’t add newlines to the
ends of files.
-N
(--noconvert)
Disable automatic conversion of
files from DOS/Mac format.
-O
(--morespace)
Use the blank line below the
titlebar as extra editing space.
-Q str
(--quotestr=str)
Set the quoting string for
justifying. The default is
"^([ \t]*[#:>\|}])+" if extended
regular expression support is available, or
"> " otherwise. Note that \t
stands for a Tab.
-R
(--restricted)
Restricted mode: don’t
read or write to any file not specified on the command line;
read any nanorc files; allow suspending; allow a file
to be appended to, prepended to, or saved under a different
name if it already has one; or use backup files or spell
checking. Also accessible by invoking nano with any
name beginning with ’r’ (e.g.
"rnano").
-S
(--smooth)
Enable smooth scrolling. Text
will scroll line-by-line, instead of the usual
chunk-by-chunk behavior.
-T cols
(--tabsize=cols)
Set the size (width) of a tab
to cols columns. The value of cols must be
greater than 0. The default value is 8.
-U
(--quickblank)
Do quick statusbar blanking.
Statusbar messages will disappear after 1 keystroke instead
of 25. Note that -c overrides this.
-V
(--version)
Show the current version number
and exit.
-W
(--wordbounds)
Detect word boundaries more
accurately by treating punctuation characters as part of a
word.
-Y str
(--syntax=str)
Specify a specific syntax
highlighting from the nanorc to use, if
available.
-c
(--const)
Constantly show the cursor
position. Note that this overrides -U.
-d
(--rebinddelete)
Interpret the Delete key
differently so that both Backspace and Delete work properly.
You should only need to use this option if Backspace acts
like Delete on your system.
-h
(--help)
Show a summary of command line
options and exit.
-i
(--autoindent)
Indent new lines to the
previous line’s indentation. Useful when editing
source code.
-k
(--cut)
Enable cut from cursor to end
of line.
-l
(--nofollow)
If the file being edited is a
symbolic link, replace the link with a new file instead of
following it. Good for editing files in /tmp,
perhaps?
-m
(--mouse)
Enable mouse support, if
available for your system. When enabled, mouse clicks can be
used to place the cursor, set the mark (with a double
click), and execute shortcuts. The mouse will work in the X
Window System, and on the console when gpm is running.
-o dir
(--operatingdir=dir)
Set operating directory. Makes
nano set up something similar to a chroot.
-p
(--preserve)
Preserve the XON and XOFF
sequences (^Q and ^S) so they will be caught by the
terminal.
-q
(--quiet)
Do not report errors in the
nanorc file and ask them to be acknowledged by
pressing Enter at startup.
-r cols
(--fill=cols)
Wrap lines at column
cols. If this value is 0 or less, wrapping will occur
at the width of the screen less cols columns,
allowing the wrap point to vary along with the width of the
screen if the screen is resized. The default value is
-8.
-s prog
(--speller=prog)
Enable alternative spell
checker command.
-t
(--tempfile)
Always save changed buffer
without prompting. Same as Pico’s -t
option.
-u
(--undo)
Enable experimental
generic-purpose undo code. By default, the undo and redo
shortcuts are Meta-U and Meta-E, respectively.
-v
(--view)
View file (read only) mode.
-w
(--nowrap)
Disable wrapping of long
lines.
-x
(--nohelp)
Disable help screen at bottom
of editor.
-z
(--suspend)
Enable suspend ability.
-$
(--softwrap)
Enable ’soft
wrapping’. nano will attempt to display the
entire contents of a line, even if it is longer than the
screen width. Since ’$’ normally refers to a
variable in the Unix shell, you should specify this option
last when using other options (e.g. ’nano
-wS$’) or pass it separately (e.g. ’nano
-wS -$’).
-a, -b,
-e, -f, -g, -j
Ignored, for compatibility with
Pico.

initialization file
nano will read initialization files in the following
order: SYSCONFDIR/nanorc, then ~/.nanorc. Please
see nanorc(5) and the example file nanorc.sample,
both of which should be provided with nano.
notes
If no alternative spell checker command is specified on the
command line or in one of the nanorc files, nano
will check the SPELL environment variable for one.
In some cases nano will try to dump the buffer into an
emergency file. This will happen mainly if nano receives a
SIGHUP or SIGTERM or runs out of memory. It will write the buffer
into a file named nano.save if the buffer didn’t have a
name already, or will add a ".save" suffix to the current
filename. If an emergency file with that name already exists in
the current directory, it will add ".save" plus a number (e.g.
".save.1") to the current filename in order to make it unique. In
multibuffer mode, nano will write all the open buffers to
their respective emergency files.
