Usage
|
||||
-----
|
||||
sxiv has no useful command line options yet, but they will be added in the next
|
||||
releases. Right now, it simply displays all files given on the command line.
|
||||
sxiv supports the following command-line options:
|
||||
|
||||
-w WIDTHxHEIGHT set window width to WIDTH and height to HEIGHT
|
||||
(if HEIGHT is omitted, height is also set to WIDTH)
|
||||
|
||||
Use the following keys to control sxiv:
