.TH NSXIV 1 nsxiv\-VERSION .SH NAME nsxiv \- Neo Simple X Image Viewer .SH SYNOPSIS .B nsxiv .RB [ \-abcfhiopqrtvZ0 ] .RB [ \-A .IR FRAMERATE ] .RB [ \-e .IR WID ] .RB [ \-G .IR GAMMA ] .RB [ \-g .IR GEOMETRY ] .RB [ \-N .IR NAME ] .RB [ \-n .IR NUM ] .RB [ \-S .IR DELAY ] .RB [ \-s .IR MODE ] .RB [ \-z .IR ZOOM ] .IR FILE ... .SH DESCRIPTION nsxiv is a simple image viewer for X. .P It has two modes of operation: image and thumbnail mode. The default is image mode, in which only the current image is shown. In thumbnail mode a grid of small previews is displayed, making it easy to choose an image to open. .P Please note, that the fullscreen mode requires an EWMH/NetWM-compliant window manager. .SH OPTIONS .TP .BI "\-A " FRAMERATE Play animations with a constant frame rate set to .IR FRAMERATE . .TP .B \-a Play animations of multi-frame images. .TP .B \-b Do not show statusbar at the bottom of the window. .TP .B \-c Remove all orphaned cache files from the thumbnail cache directory and exit. .TP .BI "\-e " WID Embed nsxiv's window into window whose ID is .IR WID . .TP .B \-f Start in fullscreen mode. .TP .BI "\-G " GAMMA Set image gamma to GAMMA (\-32..32). .TP .BI "\-g " GEOMETRY Set window position and size. See section GEOMETRY SPECIFICATIONS of X(7) for more information on GEOMETRY argument. .TP .BI "\-N " NAME Set the resource name of nsxiv's X window to NAME. .TP .BI "\-n " NUM Start at picture number NUM. .TP .B \-h Print brief usage information to standard output and exit. .TP .B \-i Read names of files to open from standard input. Also done if FILE is `-'. .TP .B \-o Write list of all marked files to standard output when quitting. In combination with .B \-i nsxiv can be used as a visual filter/pipe. .TP .B \-p Enable private mode, in which nsxiv does not write any cache or temporary files. .TP .B \-q Be quiet, and disable warnings to standard error stream. .TP .B \-r Search the given directories recursively for images to view. .TP .BI "\-S " DELAY Start in slideshow mode. Set the delay between images to .I DELAY seconds. .I DELAY may be a floating-point number. .TP .BI "\-s " MODE Set scale mode according to MODE character. Supported modes are: [d]own, [f]it, [F]ill, [w]idth, [h]eight. .TP .B \-t Start in thumbnail mode. .TP .B \-v Print version information to standard output and exit. .TP .B \-Z The same as `\-z 100'. .TP .BI "\-z " ZOOM Set zoom level to ZOOM percent. .TP .B \-0 Use NULL-separator. With this option, output of \-o and file-list sent to the key-handler and the input of \-i will be separated by a NULL character. .SH KEYBOARD COMMANDS .SS General The following keyboard commands are available in both image and thumbnail modes: .TP .BR 0 \- 9 Prefix the next command with a number (denoted via .IR count ). .TP .B q Quit nsxiv. .TP .B Return Switch to thumbnail mode / open selected image in image mode. .TP .B f Toggle fullscreen mode. .TP .B b Toggle visibility of statusbar at the bottom of the window. .TP .B Ctrl-x Send the next key to the external key-handler.

Defaults to window.foreground .TP Please see xrdb(1) on how to change them. .SH WINDOW TITLE The window title can be replaced with the output of a user-provided script, which is called by nsxiv whenever there's a redraw. The path of this script is .I $XDG_CONFIG_HOME/nsxiv/exec/win-title and the arguments given to it (where "Optional" arguments might be empty) are: .IP $1 4 resolved absolute path of the current file .IP $2 4 current file number .IP $3 4 total file count .IP $4 4 image width (Optional: Disabled on thumbnails mode) .IP $5 4 image height (Optional: Disabled on thumbnails mode) .IP $6 4 current zoom (Optional: Disabled on thumbnails mode) .P The term file is used rather than image as nsxiv does not precheck that the input files are valid images. Total file count may be different from the actual count of valid images. .P There is also an example script installed together with nsxiv as .IR EGPREFIX/win-title . .SH STATUS BAR The information displayed on the left side of the status bar can be replaced with the output of a user-provided script, which is called by nsxiv whenever an image gets loaded. The path of this script is .I $XDG_CONFIG_HOME/nsxiv/exec/image-info and the arguments given to it are: .IP $1 4 path to image file .IP $2 4 image width .IP $3 4 image height .P There is also an example script installed together with nsxiv as .IR EGPREFIX/image-info . .SH EXTERNAL KEY HANDLER Additional external keyboard commands can be defined using a handler program located in .IR $XDG_CONFIG_HOME/nsxiv/exec/key-handler . The handler is invoked by pressing .BR Ctrl-x . The next key combo is passed as its first argument. Passed via stdin are the images to act upon: all marked images, if in thumbnail mode and at least one image has been marked, otherwise the current image. nsxiv(1) will block until the handler terminates. It then checks which images have been modified and reloads them. By default nsxiv(1) will send one image per-line to stdin, however when using \-0 the image list will be NULL separated and the environment variable "$NSXIV_USING_NULL" will be set to 1. The key combo argument has the following form: "[C-][M-][S-]KEY", where C/M/S indicate Ctrl/Meta(Alt)/Shift modifier states and KEY is the X keysym as listed in /usr/include/X11/keysymdef.h without the "XK_" prefix. If KEY has an uppercase equivalent, S-KEY is resolved into it. For instance, K replaces S-k and Scedilla replaces S-scedilla, but S-Delete is sent as-is. There is also an example script installed together with nsxiv as .IR EGPREFIX/key-handler . .SH THUMBNAIL CACHING nsxiv stores all thumbnails under .IR $XDG_CACHE_HOME/nsxiv/ . .P Use the command line option .I \-c to remove all orphaned cache files. Additionally, run the following command afterwards inside the cache directory to remove empty subdirectories: .P .RS find . \-depth \-type d \-empty ! \-name '.' \-exec rmdir {} \\; .RE .SH ORIGINAL AUTHOR .EX Bert Muennich .EE .SH CURRENT MAINTAINERS .EX N-R-K Berke Kocaoğlu TAAPArthur eylles mamg22 LuXu explosion-mental Guilherme Freire Stein Gunnar Bakkeby Anupam Ashish Minz Sam Whitehead Kian Kasad qsmodo .EE .SH CONTRIBUTORS .EX Bastien Dejean Dave Reisner Fung SzeTat Max Voit For additional contributors, run `git shortlog -s` in the nsxiv repository. .EE .SH HOMEPAGE .TP Website: .EE https://nsxiv.github.io/nsxiv/ .EX .TP Source code: .EE https://github.com/nsxiv/nsxiv .EX .SH SEE ALSO .BR X (7), .BR xrdb (1)
