[Jaime Vargas <jev@xxxxxxx>]

Still no luck. Am I missing something stupid?

nerd% ./zpty-test.zsh
+./zpty-test.zsh:4> zmodload zsh/zpty
+./zpty-test.zsh:8> zpty scppty scp hello.world 'user@host:~/'
+./zpty-test.zsh:9> zpty -t scppty
+./zpty-test.zsh:10> zpty -r scppty line assword:

#!/opt/csw/bin/zsh
set -x
zmodload zsh/zpty
die() {print -r -- $1 >&2; exit 1;}
zpty scppty scp hello.world user@host:~/
zpty -t scppty || die "fuck"
zpty -r scppty line "assword:" || die "no password asked"
zpty -w scppty "TopSecret"
while zpty -r scppty line;
    do
        result+="$line"$'\n'
    done
zpty -d scppty
print $result
