.Sh CONFIGURATION
|
|
.Nm
|
|
uses \fIxdg-open\fR (on Linux) and \fIopen(1)\fR (on OS X) as the desktop
|
|
opener. It invokes
|
|
.Pa nlay
|
|
to run desktop search utility or screensaver. Read more on
|
|
.Pa nlay
|
|
at:
|
|
.br
|
|
.Em https://github.com/jarun/nnn/wiki/all-about-nlay
|
|
.Pp
|
|
Configuring
|
|
.Nm
|
|
to change to the last visited directory on quit requires shell integration in a
|
|
few easy steps. Please visit the project page (linked below) for the
|
|
instructions.
|
|
.Sh FILTERS
|
|
Filters support regexes to display only the matched
|
|
entries in the current directory view. This effectively allows
|
|
searching through the directory tree for a particular entry. Matching entries
|
|
are shown instantly (search-as-you-type).
|
|
.Pp
|
|
Filters do not stack on top of each other. They are applied anew
|
|
every time. There are 4 ways to reset a filter: \fI^L\fR, an empty filter
|
|
expression, a search with no results or an extra backspace at the filter prompt
|
|
(like vi).
|
|
.Pp
|
|
If you want to list all matches starting with the filter expression (a common
|
|
use case), start the expression with a
|
|
.Pa ^
|
|
(caret) symbol.
|
|
.Pp
|
|
If
|
|
.Nm
|
|
is invoked as root the default filter will also match hidden files.
|
|
.Pp
|
|
In the \fInavigate-as-you-type mode\fR directories are opened in filter mode,
|
|
allowing continuous navigation. Works best with the \fBarrow keys\fR.
|
|
.Sh ENVIRONMENT
|
|
The SHELL, EDITOR and PAGER environment variables take precedence
|
|
when dealing with the !, e and p commands respectively.
|
|
.Pp
|
|
\fBNNN_USE_EDITOR:\fR use EDITOR (preferably CLI, fallback vi) to handle text
|
|
files.
|
|
.Bd -literal
|
|
export NNN_USE_EDITOR=1
|
|
.Ed
|
|
.Pp
|
|
\fBNNN_DE_FILE_MANAGER:\fR set to a desktop file manager to open the current
|
|
directory with. E.g.:
|
|
.Bd -literal
|
|
export NNN_DE_FILE_MANAGER=thunar
|
|
.Ed
|
|
.Pp
|
|
\fBNNN_IDLE_TIMEOUT:\fR set idle timeout (in seconds) to invoke terminal
|
|
screensaver.
|
|
.Pp
|
|
\fBNNN_COPIER:\fR set to a clipboard copier script. For example, on Linux:
|
|
.Bd -literal
|
|
-------------------------------------
|
|
#!/bin/sh
|
|
|
|
echo -n $1 | xsel --clipboard --input
|
|
-------------------------------------
