我正在尝试使用Expect确定应用程序RA-POS是否在Mac上运行在远程Windows XP上。我通过PHP页面发送此信息，希望在该页面上返回结果作为初始测试。不幸的是，当我全部运行它们时，结果是命令行提示符，而不是有关程序是否正在运行的实际信息。最后我想创建一个条件，其中expect根据RA-POS是否正在运行返回值1或0，然后继续到另一个脚本或停止该过程。
这是期望
#!/usr/bin/expect -d
set login "administrator"
set password "password"
set machineid [lindex $argv 0]
set portid [lindex $argv 1]
set cmdprompt "C:\Documents and Settings\Administrator>"
set output $expect_out(0,string)
spawn telnet -l administrator $machineid.noerrpole.com $portid
expect "password:"
send "$password\r"
expect "$cmdprompt"
send "tasklist /nh /FI \"IMAGENAME eq RA-POS.exe\"\r"
expect -re "(INFO:*)\r"
send_user "$expect_out(0,string)\n"
expect "$cmdprompt"
send "exit\r"
interact
这是PHP
<?php
echo "<html>";
echo "<head>";
echo "<title>Turn off Windows Automatic Update</title>";
echo "</head>";
echo "<body>";
echo '<img src="NOERRlogofinal.jpg">';
echo "<br>";
echo "<br>";
echo "<pre>";
$portoffset = 1000 * $_POST["station"];
$port = 21023 + $portoffset;
$mall = $_POST["mall"];
$cmd = "/usr/bin/expect /home/dev/www/RAPOStest " . $_POST["mall"] . " " . $port;
echo "Running " . $cmd;
$retval = system($cmd);
echo "<br>";
echo "sss <br>";
echo "$retval";
echo "sss <br>";
echo "</pre>";
echo "<br>Your POS has been updated " . $_POST["mall"];
echo "<br>";
echo "<br>";
echo "</body>";
echo "</html>";
这是输出......
