tldr:

• wget can skip existing download
• after research, i found out the aria2c are more faster download between wget/curl. but aria2c doesn't have progress bar download, it's annoying me when i don't know how far along the download process is.
• using trap to handle signint (CTRL+C) , if stopped while wget still downloading it will be delete uncompleted download.
• the most wallpaper size are big, but it's posible to stop and continue it anytime.
