Re^2: Perl and cat > wpa_supplicant/.config << "EOF"

Hi Choroba,

That's just what I'm looking for.

Why does $out need the curly brackets?

Can I also put lines like:


CONFIG_PEERKEY=$yorn
[download]

in the data?

Regards

Steve.

Why does $out need the curly brackets? It does not. `$OUT{wpa}` would need them, though, if the file handles were stored in a hash. I use it just to make it visually more distinct from `print $OUT, $data`. See <<EOF on how to make a here document interpolate variables (basically, just use double quotes when introducing the terminating string). لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]
