nsxiv:tldr:9515d
The command "nsxiv -r ${path-to-directory1 path-to-directory2 ---}" is likely referring to the usage of the "nsxiv" command-line program with the "-r" option and multiple directory path arguments. Below is an explanation of each component:
-
"nsxiv": This is the name of the command-line program, and it is commonly used as an image viewer in Unix-like operating systems.
-
"-r": This is an option or flag for the "nsxiv" program. The specific functionality of this option may vary depending on the program's implementation. In this case, it could potentially refer to recursively scanning directories for image files.
-
"${path-to-directory1 path-to-directory2 ---}": This represents the placeholder for specifying one or more directory paths. "path-to-directory1" and "path-to-directory2" are placeholders for actual directory paths. "---" indicates the end of the option/flag section in some command-line programs.
Overall, this command is likely used to recursively display and view image files in the specified directory paths using the "nsxiv" program.
