.Sh CONFIGURATION
|
|
There is no configuration file. Associated files are at
|
|
.Pp
|
|
.Pa ${XDG_CONFIG_HOME:-$HOME/.config}/nnn/
|
|
.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
|
|
Open multiple locations 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. Sessions can be loaded at runtime or with a program
|
|
option.
|
|
.Pp
|
|
- When a session is loaded at runtime, the last working state is saved
|
|
automatically to a dedicated "auto session" session file. Session option
|
|
\fIrestore\fR would restore the "auto session".
|
|
.br
|
|
- The persistent session option is global. If it is used, the last active session
|
|
will be updated with the final state at program quit.
|
|
.br
|
|
- The "auto session" is used in persistent session mode if no session is active.
|
|
.br
|
|
- Listing input stream and opening a bookmark by key have a higher priority to
|
|
session options (-s/-S).
|
|
.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 "auto 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
|
|

.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. Selection from multiple instances are not merged. The last instance
|
|
writing to the file overwrites earlier contents. If you have 2 instances of
|
|
.Nm
|
|
\fIopen\fR in 2 panes of a terminal multiplexer, you can select in one pane and
|
|
use the selection in the other pane.
|
|
.Pp
|
|
.Nm
|
|
clears the selection after an operation with the selection. Plugins are allowed
|
|
to define the behaviour individually.
|
|
.Pp
|
|
.Nm
|
|
doesn't match directory entries for selected files after a redraw or after the
|
|
user navigates away from the directory. An attempt to do so will increase
|
|
memory consumption and processing significantly as
|
|
.Nm
|
|
allows selection across directories. So the selection marks are cleared. The
|
|
selection can still be edited in the same instance.
|
|
.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 or to remove
|
|
duplicates. 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 FIND AND LIST
|
|
There are two ways to search and list:
|
|
.Pp
|
|
- feed a list of file paths as input
|
|
.br
|
|
- search using a plugin (e.g. \fIfinder\fR) and list the results
|
|
.Pp
|
|
File paths must be NUL-separated ('\\0'). Paths and can be relative to the
|
|
current directory or absolute. Invalid paths in the input are ignored. Input
|
|
limit is 65,536 paths or 256 MiB of data.
|
|
.Pp
|
|
To list the input stream, start
|
|
.Nm
|
|
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
|
|
Listing input stream can be scripted. It can be extended to pick (option -p)
|
|
selected entries from the listed results.
|
|
.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, VISUAL (else EDITOR) and PAGER environment variables are
|
|
used. A single combination of arguments is supported for SHELL and PAGER.
|
|
.Pp
|
|
\fBNNN_OPTS:\fR binary options to

.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.

export NNN_BMS="d:$HOME/Docs;u:/home/user/Cam Uploads;D:$HOME/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='p:-plugin'
|
|
.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'
|
|
|
|
To pick and run an unassigned plugin, press \fBEnter\fR at the plugin prompt.
|
|
To run a plugin at startup, use the option `-P` followed by the plugin key.
|
|
|
|
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'
|
|
|
|
7. To show the output of run-and-exit commands which do not need user input,
|
|
add \fB|\fR (pipe) after \fB!\fR
|
|
Note: This option is incompatible with \fB&\fR (terminal output is masked
|
|
for GUI programs) and ignores \fB*\fR (output is already paged for user)
|
|
|
|
export NNN_PLUG='m:-!|mediainfo $nnn;t:-!|tree -ps;l:-!|ls -lah --group-directories-first'
