在/bin/bash中使expect off

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

#!/bin/bash #定义一个变量pw pw=123456   function vncpw(){ /usr/bin/expect <<eof set timeout 10 spawn vncpasswd   expect "Password:" send "$pw\n" expect "Verify:" send "$pw\n"   expect "password (y/n)?" send   "n\n" expect eof eof }   vncpw

　以上命令将会生成文件 /root/.vnc/passwd

使用下面的命令将不会生成/root/.vnc/passwd #!/bin/bash pw=123456   function vncpw(){ /usr/bin/expect <<eof set timeout 10 spawn vncpasswd   expect "Password:" send "$pw\n" expect "Verify:" send "$pw\n"   expect "password (y/n)?" send   "n\n" interact  eof }   vncpw
