DuckDuckGo request command line:

Adding the code bellow in your .bashrc file:

    search=""; bang=""; zeroc=0;
    for term in $@;
     if [ "$term" = "-z" ];
        then zeroc=1
     elif [[ "$term" =~ -([A-Za-z0-9._%+-]*) ]];
        then bang="!${BASH_REMATCH[1]}"
    if [ $zeroc -eq 1 ];
      then w3m  "$bang$search" | sed -n "/Zero-click/,/More at/p" ;
      w3m  "$bang$search" ;
short version:
ddg(){ search=""; bang=""; for term in $@;  do  if [[ "$term" =~ -([A-Za-z0-9._%+-]*) ]]; then bang="!${BASH_REMATCH[1]}" ; else search="$search%20$term" ; fi ;  done ; w3m  "$bang$search" ;}
give you the possibility to ask for

It seems that I was not the first one to wish such a tool... A similar one (not giving direct answer as ddg -z and ggn) is already existing, and has been created by Julian Assange (the known one).

Videotop: command line youtube browser

This is a "command line browser" for youtube you can find here (I'm not the author of this!).
Using this

depends on the following packages: be sure to have an updated youtube-dl version and you may need to add in the '--prefer-insecure' as youtube-dl argument at line 126, mplayer not being able to handle https urls (here) and browsing is similar to vim. Below, an example of YouTube browsing after a search using: ":s Hello World" (or ":search Hello World"): videotop

Pressing Enter starts the download of the vid, pressing "p" plays the downloaded video, and "s" will start the streaming in mplayer without downloading for offline use.
