Many thanks. As it happens, I'm only interested in capturing stdout. I
tried 3 x variations, based on your suggestions:-
Attempt #1:
my $output = 'gtk-update-icon-cache --force
--ignore-theme-index --source builtin_icons gtk/stock-icons';
Response a) - simply running 'my_perl-script.pl' produces no output file.
Response b) - running 'my_perl_script.pl > test.txt' produces an output
file called "test.txt" but it's still empty.
Attempt #2:
use IPC::Run3;
my $output;
run3(["gtk-update-icon-cache", "--force",
"--ignore-theme-index", "--source", "builtin_icons", "gtk/stock-icons"],
undef, \$output);
Response a) - simply running 'my_perl-script.pl' produces no output file.
Response b) - running 'my_perl_script.pl > test.txt' produces this error
message:-
run3(): Permission denied saving STDOUT at
F:\GTK-SOURCES\my_per_script.pl line 6.
Attempt #3:
use IPC::Run3;
my $output;
run3(["gtk-update-icon-cache", "--force",
"--ignore-theme-index", "--source", "builtin_icons", "gtk/stock-icons"],
undef, \$std_out);
Responses are identical to attempt #2
It seems so near and yet so far away!
