vifm-thumbnailer
|
||
|
|
|
||
|
|
Easily show images/thumbnails from the vifm file manager.
|
||
|
|
|
||
|
|
Usage: vifm-thumbnailer <current file>
|
||
|
|
|
||
|
|
Point it to a file whose directory you want thumbnailed.
|
||
|
|
If you point it to a directory itself, it will list its contents.
|
||
|
|
|
||
|
|
Options:
|
||
|
|
|
||
|
|
-h Display this help.
|
||
|
|
|
||
|
|
-r Show images recursively from current folder.
|
||
|
|
|
||
|
|
-t Open viewer in thumbnail mode.
|
||
|
|
|
||
|
|
-m Show thumbnails for video files in addition to image files.
|
||
|
|
Will take longer to load up and requires ffmpeg utilities.
|
||
|
|
|
||
|
|
Vifm:
|
||
|
|
|
||
|
|
If the file is on your path (e.g. in ~/.vifm/scripts) from within
|
||
|
|
vifm you can run the script by invoking it with:
|
||
|
|
\`:!vifm-thumbnailer \%%c\`
|
||
|
|
which will show all directory thumbnails with the current file
|
||
|
|
initially shown.
|
||
|
|
|
||
|
|
If you want to have vifm show a filtered view for selected files
|
||
|
|
afterwards add a \%%u to the command.
