          Try using the -o flag, to only print matching strings, e.g.



          $ cat <<HEREDOC | grep -Po 'w+'

          • Did you mean grep -Po 'w+' HEREDOC? This works, thank you.

          • No, I meant what I wrote there - it works for me if I copy-paste it. In practice, I imagine you would use a file instead of a heredoc string, and it would look like grep -Po 'w+' /path/to/file.

          • Substituting HEREDOC for path to file, cat <<HEREDOC | grep -Po 'w+' doesn't work for me while cat HEREDOC | grep -Po 'w+' (or better grep -Po 'w+' HEREDOC) works fine.

          • It sounds to me like you're confused about what a heredoc is - it's not supposed to represent a file path. You can read more about "here documents" in the Bash manual: gnu.org/software/bash/manual/bashref.html#Here-Documents

          Replacing all matches of W with newlines, using Perl (from which the W expression originated):



          $ perl -pe '$_ =~ s/W/n/g' <file
          
www
          
wifi
          
in
          
ua
          
YI
          
HondBrychka


          Or, more in line with the actual wording of the question:



          $ perl -pe '$_ = join("n", split(/W/)) . "n"' <file
          
www
          
wifi
          
in
          
ua
          
YI
          
HondBrychka


          Expressing the PCRE W as the ERE [^[:alnum:]] and using GNU awk:



          awk -v RS='[^[:alnum:]]' 1 file


          The 1 is short for '{ print }' and this sets the input record separator to any W character. The records are then printed on individual lines.



          Or with GNU sed:



          sed 's/[^[:alnum:]]/n/g' file


          With tr, it becomes



          $ tr -c '[:alnum:]' 'n' <file
          
www
          
wifi
          
in
          
ua
          
YI
          
HondBrychka


          where -c makes it replace each character that is not an [:alnum:] with a newline.

          • @dizcza Add -s to the command line. It will make it squeeze multiple newlines into one. But on the other hand, you do have an empty word between 9 and 8.

          The 1 is short for '{ print }' and this sets the input record separator to any W character. The records are then printed on individual lines.

          • The last solution has an artifact of empty new lines. Compare tr -c '[:alpha:]' 'n' < HEREDOC with grep -Po '[a-zA-Z]+' HEREDOC if we add "Zhenek_Lebed98" to the input file HEREDOC.

          • @dizcza Add -s to the command line. It will make it squeeze multiple newlines into one. But on the other hand, you do have an empty word between 9 and 8.

          ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

          Image
          0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited. ...
