Its a bug in Raku:
qqx tries to run the module, not the sub inside the module:
Windows 10 Pro 21H2
Windows 11 Pro 22H2
https://rakudo.org/dl/rakudo/rakudo-moar-2022.07-01-win-x86_64-msvc.msi
When you run this sub inside your program, there is no issue.
If you put the sub into a module, then qqx tries to
run the module itself, not the batch file this sub
creates:
<RunCmdModule.pm6>
# unit module RunCmdModule;
# RunCmdModule.pm6
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";
}
</RunCmdModule.pm6>
Test one liner (run in the same directory as the module):
raku -e "use lib '.'; use RunCmdModule :RunCmd; say RunCmd(Q[ls]);
Result: Windwos tries to run a .pm6 file
