Hi All, Windows Pro Chromebook Edition 22H2 (W11) raku -v Welcome to RakudoΓäó v2022.07. When ever I run the following, it opens a Notepad with the text of the calling raku program. raku -e "use lib '.'; use NativeWinUtils :RunCmd; say RunCmd(Q[ls]);" This is RunCmd sub RunCmd( Str $CommandStr, Bool $EchoOff = False ) returns Str is export( :RunCmd ) { my $PathIAm = $?FILE; my Str $BatFile = $PathIAm ~ ".bat"; # print "$BatFile\n"; my Str $RtnStr; my Str $CmdStr = ""; if $EchoOff { $CmdStr = Q[@echo off] ~ "\n"; } $CmdStr = $CmdStr ~ $CommandStr ~ "\n"; # print "$CmdStr"; spurt( $BatFile, $CmdStr ); $RtnStr = qqx { $BatFile }; # print "$RtnStr\n"; } It is the qqx command (it runs the created .bat file) that opens the notepad. The .bat file, which I leave on the disk, runs fine manually. And I did this to myself. I had a pop up that asked me what to do with something and I must have clicked on it by accident. -TThread Next
