pico
nano 基于 pico,Pico是由华盛顿大学(University of Washington)计算与通讯研究所(Computing and Communications Group)编写并维护的文本编辑程序。
nano 是基于字符终端的文本编辑器。它比 vi/vim 要简单得多,适合 Linux 初学者使用。某些 Linux 发行版的默认编辑器就是 nano
nano [options] [[+line[,column]] file]... nano [options] [[+[crCR](/|?)string] file]...
OPTIONS -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 back- wards). 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, using the current filename suffixed with a tilde (~). -C directory, --backupdir=directory Make and keep not just one backup file, but make and keep a uniquely numbered one every time a file is saved -- when backups are enabled (-B). The uniquely numbered files are stored in the specified directory. -D, --boldtext For the interface, use bold instead of reverse video. This will be overridden by setting the options titlecolor, statuscolor, keycolor, functioncolor, numbercolor, and/or selectedcolor in your nanorc file. See nanorc(5). -E, --tabstospaces Convert each typed tab to spaces -- to the number of spaces that a tab at that position would take up. -F, --multibuffer Read a file into a new buffer by default. -G, --locking Use vim-style file locking when editing files. -H, --historylog Save the last hundred search strings and replacement strings and executed commands, so they can be easily reused in later ses- sions. -I, --ignorercfiles Don't look at the system's nanorc nor at the user's nanorc. -J number, --guidestripe=number Draw a vertical stripe at the given column, to help judge the width of the text. (The color of the stripe can be changed with set stripecolor in your nanorc file.) -K, --rawsequences Interpret escape sequences directly (instead of asking ncurses to translate them). If you need this option to get your key- board to work properly, please report a bug. Using this option disables nano's mouse support. -L, --nonewlines Don't automatically add a newline when a text does not end with one. (This can cause you to save non-POSIX text files.) -M, --trimblanks Snip trailing whitespace from the wrapped line when automatic hard-wrapping occurs or when text is justified. -N, --noconvert Disable automatic conversion of files from DOS/Mac format. -O, --bookstyle When justifying, treat any line that starts with whitespace as the beginning of a paragraph (unless auto-indenting is on). -P, --positionlog For the 200 most recent files, log the last position of the cur- sor, and place it at that position again upon reopening such a file. -Q "regex", --quotestr="regex" Set the regular expression for matching the quoting part of a line. The default value is "^([ \t]*([!#%:;>|}]|//))+". (Note that \t stands for an actual Tab.) This makes it possible to rejustify blocks of quoted text when composing email, and to re- wrap blocks of line comments when writing source code. -R, --restricted Restricted mode: don't read or write to any file not specified on the command line. This means: don't read or write history files; don't allow suspending; don't allow spell checking; don't allow a file to be appended to, prepended to, or saved under a different name if it already has one; and don't make backup files. Restricted mode can also be activated by invoking nano with any name beginning with 'r' (e.g. "rnano"). -S, --softwrap Display over multiple screen rows lines that exceed the screen's width. (You can make this soft-wrapping occur at whitespace instead of rudely at the screen's edge, by using also --atblanks.) (The old short option, -$, is deprecated.) -T number, --tabsize=number Set the size (width) of a tab to number columns. The value of number must be greater than 0. The default value is 8. -U, --quickblank Make status-bar messages disappear after 1 keystroke instead of after 20. Note that options -c (--constantshow) and -_ (--mini- bar) override this. -V, --version Show the current version number and exit. -W, --wordbounds Detect word boundaries differently by treating punctuation char- acters as part of a word. -X "characters", --wordchars="characters" Specify which other characters (besides the normal alphanumeric ones) should be considered as part of a word. When using this option, you probably want to omit -W (--wordbounds). -Y name, --syntax=name Specify the name of the syntax highlighting to use from among the ones defined in the nanorc files. -Z, --zap Let an unmodified Backspace or Delete erase the marked region (instead of a single character, and without affecting the cut- buffer). -a, --atblanks When doing soft line wrapping, wrap lines at whitespace instead of always at the edge of the screen. -b, --breaklonglines Automatically hard-wrap the current line when it becomes over- long. (This option is the opposite of -w (--nowrap) -- the last one given takes effect.) -c, --constantshow Constantly show the cursor position on the status bar. Note that this overrides option -U (--quickblank). -d, --rebinddelete Interpret the Delete and Backspace keys differently so that both Backspace and Delete work properly. You should only use this option when on your system either Backspace acts like Delete or Delete acts like Backspace. -e, --emptyline Do not use the line below the title bar, leaving it entirely blank. -f file, --rcfile=file Read only this file for setting nano's options, instead of read- ing both the system-wide and the user's nanorc files. -g, --showcursor Make the cursor visible in the file browser (putting it on the highlighted item) and in the help viewer. Useful for braille users and people with poor vision. -h, --help Show a summary of the available command-line options and exit. -i, --autoindent Automatically indent a newly created line to the same number of tabs and/or spaces as the previous line (or as the next line if the previous line is the beginning of a paragraph). -j, --jumpyscrolling Scroll the buffer contents per half-screen instead of per line. -k, --cutfromcursor Make the 'Cut Text' command (normally ^K) cut from the current cursor position to the end of the line, instead of cutting the entire line. -l, --linenumbers Display line numbers to the left of the text area. (Any line with an anchor additionally gets a mark in the margin.) -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. Text can still be selected through dragging by holding down the Shift key. -n, --noread Treat any name given on the command line as a new file. This allows nano to write to named pipes: it will start with a blank buffer, and will write to the pipe when the user saves the "file". This way nano can be used as an editor in combination with for instance gpg without having to write sensitive data to disk first. -o directory, --operatingdir=directory Set the operating directory. This 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, --indicator Display a "scrollbar" on the righthand side of the edit window. It shows the position of the viewport in the buffer and how much of the buffer is covered by the viewport. -r number, --fill=number Set the target width for justifying and automatic hard-wrapping at this number of columns. If the value is 0 or less, wrapping will occur at the width of the screen minus number 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 "program [argument ...]", --speller="program [argument ...]" Use this command to perform spell checking and correcting, instead of using the built-in corrector that calls hunspell(1) or spell(1). -t, --saveonexit Save a changed buffer without prompting (when exiting with ^X). (The old form of the long option, --tempfile, is deprecated.) -u, --unix Save a file by default in Unix format. This overrides nano's default behavior of saving a file in the format that it had. (This option has no effect when you also use --noconvert.) -v, --view Just view the file and disallow editing: read-only mode. This mode allows the user to open also other files for viewing, unless --restricted is given too. -w, --nowrap Do not automatically hard-wrap the current line when it becomes overlong. This is the default. (This option is the opposite of -b (--breaklonglines) -- the last one given takes effect.) -x, --nohelp Don't show the two help lines at the bottom of the screen. -y, --afterends Make Ctrl+Right and Ctrl+Delete stop at word ends instead of beginnings. -z, --suspendable Allow the user to suspend the editor (with ^Z by default). -%, --stateflags Use the top-right corner of the screen for showing some state flags: I when auto-indenting, M when the mark is on, L when hard-wrapping (breaking long lines), R when recording a macro, and S when soft-wrapping. When the buffer is modified, a star (*) is shown after the filename in the center of the title bar. -_, --minibar Suppress the title bar and instead show information about the current buffer at the bottom of the screen, in the space for the status bar. In this "minibar" the filename is shown on the left, followed by an asterisk if the buffer has been modified. On the right are displayed the current line and column number, the code of the character under the cursor (in Unicode format: U+xxxx), the same flags as are shown by --stateflags, and a per- centage that expresses how far the cursor is into the file (linewise). When a file is loaded or saved, and also when switching between buffers, the number of lines in the buffer is displayed after the filename. This number is cleared upon the next keystroke, or replaced with an [i/n] counter when multiple buffers are open. The line plus column numbers and the charac- ter code are displayed only when --constantshow is used, and can be toggled on and off with M-C. The state flags are displayed only when --stateflags is used. -!, --magic When neither the file's name nor its first line give a clue, try using libmagic to determine the applicable syntax.
