前提：当前Linux服务器已安装expect命令
在当前Linux服务器上，通过执行命令 sudo -u testid expect /home/test/expect.sh 20181103 201811达到调用远程服务器(192.168.1.1)上/home/testid/remote_test.sh的目的。
#!/usr/bin/expect
set timeout -1
set USER "testid"
set PWD "testpwd"
set HOST "192.168.1.1"
set YMD [lindex $argv 0]
set YM [lindex $argv 1]
spawn ssh $USER@$HOST
expect {
"*yes/no" { send "yes\r"; exp_continue }
"*password:" { send "$PWD\r"}
}
expect "$*" {
send "/home/testid/remote_test.sh \r"
}
expect {
"fail" {
send "exit \r"
exit 1
}
"success" {
send "exit \r"
exit 0
}
"$*" {
send "exit \r"
exit 2
}
}
