最简单的非交互ssh远程执行命令expect脚本

标题有点绕口~

#!/usr/bin/expect -f



if { $argc<4 } {

    puts stderr "Usage: $argv0 <host> <user> <passwd> <cmd>"

    exit 1   

}



set HOST [lindex $argv 0]

set USER [lindex $argv 1]

set PSWD [lindex $argv 2]

set CMDS [lindex $argv 3]



log_user 0

set timeout 3

spawn -noecho ssh $USER@$HOST "$CMDS"

while {1} {

    expect {

        "(yes/no)? " { send "yes\r"; continue; }

        "Password: " { send "$PSWD\r"; log_user 1 }

        eof { break }

        timeout { send_user "\[timeout\]\n"; exit 255 }

    }

}
