sxiv cannot handle filenames with newlines in input mode

[ykonstant1]

Affected system: any linux system

Description: Suppose your current directory contains a file with newline, such as $'hello\nworld.jpg'. A command such as find . -name "*.jpg" | sxiv -i will then fail, as sxiv interprets the above file as two separate inputs.

In the same manner, sxiv -o returns a newline-terminated list of files, which will cause problems for further processing in the above scenario. This is a very common trap with unix filenames, and can lead to serious security issues.

Suggestion: Tools like find and xargs include a -0 and -print0 option to return path lists as null terminated strings. My suggestion is to add a -0 option in sxiv with -i in order to accept a list of null-terminated pathnames, rather than newline-terminated. Similarly, add a -print0 option to return null-terminated output.

This will prevent breakage due to unusual filenames and make sxiv compatible with find, xargs etc.

Hi @ykonstant1

We've implemented -0 for outputting NULL separated list on nsxiv. However option for NULL seperated input can be done easily via xargs -0 so that will not be added.
