expect批量修改linux密码

最近对linux批量执行的脚本很感兴趣,在网上到处找有关expect批量执行脚本,今天就给大家共享一个批量修改密码的脚本.脚本内容:
#!/usr/bin/expect#yemaosheng.comif { $argc<2 } {    send_user "usage: $argv0 <host file> <cmd file> \n"    exit} # 机器列表数据格式:  IP  端口  旧密码  新密码set hostfile    [ open [lindex $argv 0] ]# 命令列表数据格式:  一条命令一行set cmdfile    [ open [lindex $argv 1] ] # 数据文件分割符,默认为空格set part "\ " # 过滤关键字set key_password "password:\ "set key_init "\(yes/no\)\?\ "set key_confirm "'yes'\ or\ 'no':\ "set key_ps "*]#\ "set key_newpassword "UNIX password:\ "set timeout 30 log_file ./exprct.logmatch_max 20480 while {[gets $hostfile _hosts_] >= 0} {    set hosts [string trim $_hosts_]    set str_index [string first $part $hosts]    set host [string trim [string range $hosts 0 $str_index]]    set temp [string trim [string range $hosts [expr $str_index + 1] [string length $hosts]]]    set str_index [string first $part $temp]     if { $str_index == -1 } {        set port 22        set pass $temp        set newpass $temp    } else {        set port [string trim [string range $temp 0 $str_index]]        set temp_pass [string trim [string range $temp [expr $str_index + 1] [string length $temp]]]        set str_index [string first $part $temp_pass]        set pass [string trim [string range $temp_pass 0 $str_index]]        set newpass [string trim [string range $temp_pass [expr $str_index + 1] [string length $temp_pass]]]    }     spawn ssh -p $port $host    while {1} {        expect {            "$key_password" {                send "$pass\r"            }            "$key_init" {                send "yes\r"            }            "$key_confirm" {                send "yes\r"            }            "$key_ps" {                while {[gets $cmdfile cmd] >= 0} {                    send "$cmd\r"                    expect {                        "$key_ps" {                            continue                        }                        "$key_newpassword" {                            send "$newpass\r"                            expect "$key_newpassword" {                                send "$newpass\r"                                expect "$key_ps"                                continue                            }                        }                    }                }                seek $cmdfile 0 start                send_user "\r"                break            }            timeout {                puts "$host timeout\n"                break            }        }    }    send "exit\r"    close    wait} close $hostfileclose $cmdfile exit
