Associated files are at .Pp \fB${XDG_CONFIG_HOME:-$HOME/.config}/nnn/\fR .Pp Configuration is done using a few optional (set if you need) environment variables. See ENVIRONMENT section. .Pp .Nm uses \fIxdg-open\fR (on Linux), \fIopen(1)\fR (on macOS), \fIcygstart\fR on (Cygwin) and \fIopen\fR on (Haiku) as the desktop opener. It's also possible to specify a custom opener. See ENVIRONMENT section. .Sh CONTEXTS Explore multiple directories simultaneously with 4 contexts. The status is shown in the top left corner: .Pp - the current context is in reverse video .br - other active contexts are underlined .br - rest are inactive .Pp A new context copies the state of the previous context. Each context can have its own color. See ENVIRONMENT section. .Sh SESSIONS Sessions are a way to save and restore states of work. A session stores the settings and contexts. .Pp Sessions can be loaded dynamically from within a running .Nm instance, or with a program option. .Pp When a session is loaded dynamically, the last working session is saved automatically to a dedicated -- "last session" -- session file. The "last session" is also used in persistent session mode. .Pp All the session files are located by session name in the directory .Pp \fB${XDG_CONFIG_HOME:-$HOME/.config}/nnn/sessions\fR .Pp "@" is the "last session" file. .Sh FILTERS Filters are strings (or regex patterns) to find matching entries in the current directory instantly (\fIsearch-as-you-type\fR). Matches are case-insensitive by default. The last filter in each context is persisted at runtime or in saved sessions. .Pp Special keys at filter prompt: .Bd -literal ------ + --------------------------------------- Key | Function ------ + --------------------------------------- ^char | Usual keybind functionality Esc | Exit filter prompt but skip dir refresh ------ + --------------------------------------- .Ed .Pp Special keys at \fBempty filter prompt\fR: .Bd -literal ------ + --------------------------------------- Key | Function ------ + --------------------------------------- ? | Show help and config screen / | Toggle between string and regex : | Toggle case-sensitivity ^L | Clear filter (\fIif prompt is non-empty\fR) | OR apply last filter ------ + --------------------------------------- .Ed .Pp Additional special keys at \fBempty filter prompt\fR in \fBtype-to-nav\fR mode: .Bd -literal ------ + ------------------------ Key | Function ------ + ------------------------ ' | Go to first non-dir file + | Toggle auto-advance , | Pin CWD - | Go to last visited dir . | Show hidden files ; | Run a plugin by its key = | Launch a GUI application > | Export file list @ | Visit start dir ] | Show command prompt ` | Visit / ~ | Go HOME ------ + ------------------------ .Ed .Pp Common regex use cases: .Pp (1) To list all matches starting with the filter expression, start the expression with a '^' (caret) symbol. .br (2) Type '\\.mkv' to list all MKV files. .br (3) Use '.*' to match any character (\fIsort of\fR fuzzy search). .br (4) Exclude filenames having 'nnn' (compiled with PCRE lib): '^(?!nnn)' .Pp In the \fItype-to-nav\fR mode directories are opened in filter mode, allowing continuous navigation. .br When there's a unique match and it's a directory, .Nm auto selects the directory and enters it in this mode. Use the relevant program option to disable this behaviour. .Sh SELECTION .Nm allows file selection across directories and contexts! .Pp There are 3 groups of keybinds to add files to selection: .Pp (1) hovered file selection toggle - deselects if '+' is visible before the entry, else adds to selection .br (2) add a range of files to selection - repeat the range key on the same entry twice to clear selection completely .br (3) add all files in the current directory to selection .Pp A selection can be edited, copied, moved, removed, archived or linked. .Pp Absolute paths of the selected files are copied to \fB.selection\fR file in the config directory. The selection file is shared between multiple program instances. The most recent instance writing to the file overwrites the entries from earlier writes. If you have 2 instances if .Nm \fIopen\fR in 2 panes of a terminal multiplexer, you can select in one pane and use the selection (e.g. to copy or move) in the other pane (if the instance doesn't have any local selection already). .Pp To edit the selection use the _edit selection_ key. Use this key to remove a file from selection after you navigate away from its directory. Editing doesn't end the selection mode. You can add more files to the selection and edit the list again. If no file is selected in the current session, this option attempts to list the selection file. .Sh LIST INPUT .Nm can receive a list of NUL-separated ('\\0') file paths as input. Paths and can be relative to the current directory or absolute. .Pp Input is limited by 65,536 paths or 256 MiB of input. .Pp Start .Nm in this mode by writing to its standard input. E.g., to list files in current directory larger than 1M: .Bd -literal find -maxdepth 1 -size +1M -print0 | nnn .Ed .Pp or redirect a list from a file: .Bd -literal nnn < files.txt .Ed .Pp Handy bash/zsh shell function to list files by mime-type in current directory: .Bd -literal # to show video files, run: list video list () { find . -maxdepth 1 | file -if- | grep "$1" | awk -F: '{printf "%s\0", $1}' | nnn } .Ed .Pp A temporary directory will be created containing symlinks to the given paths. Any action performed on these symlinks will be performed only on their targets, after which they might become invalid. .Pp Right arrow or 'l' on a symlink in the listing dir takes to the target file. Press '-' to return to the listing dir. Press 'Enter' to open the symlink. .Pp \fBInvalid paths in the input are ignored.\fR .Sh UNITS The minimum file size unit is byte (B). The rest are K, M, G, T, P, E, Z, Y (powers of 1024), same as the default units in \fIls\fR. .Sh ENVIRONMENT The SHELL, EDITOR (VISUAL, if defined) and PAGER environment variables are used. A single combination of arguments is supported for SHELL and PAGER. .Pp \fBNNN_OPTS:\fR binary options to .Nm .Bd -literal export NNN_OPTS="cEnrx" .Ed .Pp \fBNNN_OPENER:\fR specify a custom file opener. .Bd -literal export NNN_OPENER=nuke NOTE: 'nuke' is a file opener available in the plugin repository. .Ed .Pp \fBNNN_BMS:\fR bookmark string as \fIkey_char:location\fR pairs separated by \fI;\fR: .Bd -literal export NNN_BMS='d:~/Documents;u:/home/user/Cam Uploads;D:~/Downloads/' .Ed .Pp \fBNNN_PLUG:\fR directly executable plugins as \fIkey_char:plugin\fR pairs separated by \fI;\fR: .Bd -literal export NNN_PLUG='f:finder;o:fzopen;p:mocplay;d:diffs;t:nmount;v:imgview' NOTES: 1. To run a plugin directly, press \fI;\fR followed by the key. 2. Alternatively, combine with \fIAlt\fR (i.e. \fIAlt+key\fR). 3. To skip directory refresh after running a plugin, prefix with \fB-\fR. export NNN_PLUG='m:-mediainf' .Ed .Pp To assign keys to arbitrary non-background non-shell-interpreted cli commands and invoke like plugins, add \fI_\fR (underscore) before the command. .Bd -literal export NNN_PLUG='x:_chmod +x $nnn;g:_git log;s:_smplayer $nnn' NOTES: 1. Use single quotes for $NNN_PLUG so $nnn is not interpreted 2. $nnn should be the last argument (IF used) 3. (Again) add \fB_\fR before the command 4. To disable directory refresh after running a \fIcommand as plugin\fR, prefix with \fB-_\fR 5. To skip user confirmation after command execution, suffix with \fB*\fR Note: Do not use \fB*\fR with programs those run and exit e.g. cat export NNN_PLUG='y:-_sync*' 6. To run a \fIGUI app as plugin\fR, add a \fB|\fR after \fB_\fR export NNN_PLUG='m:-_|mousepad $nnn' EXAMPLES: ----------------------------------- + ------------------------------------------------- Key:Command | Description ----------------------------------- + ------------------------------------------------- g:-_git diff | Show git diff k:-_fuser -kiv $nnn* | Interactively kill process(es) using hovered file l:-_git log | Show git log n:-_vi /home/user/Dropbox/dir/note* | Take quick notes in a synced file/dir of notes p:-_less -iR $nnn* | Page through hovered file in less s:-_|smplayer -minigui $nnn | Play hovered media file, even unfinished download x:_chmod +x $nnn | Make the hovered file executable y:-_sync* | Flush cached writes ----------------------------------- + ------------------------------------------------- .Ed .Pp \fBNNN_COLORS:\fR string of color codes for each context, e.g.: .Bd -literal export NNN_COLORS='1234' codes: 0-black, 1-red, 2-green, 3-yellow, 4-blue (default), 5-magenta, 6-cyan, 7-white .Ed .Pp \fBNNN_ARCHIVE:\fR archive types to be handled silently (default: bzip2, (g)zip, tar). .Bd -literal export NNN_ARCHIVE="\\\\.(7z|bz2|gz|tar|tgz|zip)$" NOTE: Non-default formats may require a third-party utility. .Ed .Pp \fBNNN_SSHFS:\fR pass additional options to sshfs command: .Bd -literal export NNN_SSHFS='sshfs -o reconnect,idmap=user,cache_timeout=3600' NOTE: The options must be preceded by "sshfs" and comma-separated without any space between them. .Ed .Pp \fBNNN_RCLONE:\fR pass additional options to rclone command: .Bd -literal export NNN_RCLONE='rclone mount --read-only --no-checksum' NOTE: The options must be preceded by "rclone" and max 5 flags are supported. .Ed .Pp \fBNNN_TRASH:\fR trash (instead of \fIdelete\fR) files to desktop Trash. .Bd -literal export NNN_TRASH=1 .Ed .Pp \fBNNN_SEL:\fR absolute path to custom selection file. .Pp \fBNNN_FIFO:\fR path of a named pipe to write the hovered file path: .Bd -literal export NNN_FIFO='/tmp/nnn.fifo' NOTES: 1.
