The command>> attribute in <process> should be a string not a sequence
of strings. I think that is the core of your problem, not sure. Also,
input and output redirection is a feature of the shell, not the os, so
you need to wrap those commands in a subshell. But that is platform
dependent since not all shells are available everywhere and they dont
all have the same features. Here is how you could write a find utility
for Windows (using gnu find), maybe you can use it as a template:
USING: formatting io.launcher kernel ;
IN: cmdpipe
CONSTANT: find-bin "C:\\Program Files (x86)\\Git\\bin\\find.exe"
: shell-command ( str -- str' )
"cmd /C \"%s\"" sprintf ;
: find-command ( dir pattern out-path -- str )
[ find-bin ] 3dip "\"%s\" \"%s\" -name \"%s\" > \"%s\"" sprintf ;
: run-find ( dir pattern out-path -- proc )
find-command shell-command run-process ;
IN: scratchpad "C:\\Users\\bjourne\\Downloads" "*.pdf"
"C:\\Users\\bjourne\\result.txt" run-find
