最近對linux批量執(zhí)行的腳本很感興趣,在網上到處找有關expect批量執(zhí)行腳本,今天就給大家共享一個批量修改密碼的腳本.
    腳本內容:
    代碼如下:
    #!/usr/bin/expect
    if { $argc<2 } {
    send_user "usage: $argv0 <host file> <cmd file> \n"
    exit
    }
    # 機器列表數(shù)據(jù)格式: IP 端口 舊密碼 新密碼
    set hostfile [ open [lindex $argv 0] ]
    # 命令列表數(shù)據(jù)格式: 一條命令一行
    set cmdfile [ open [lindex $argv 1] ]
    # 數(shù)據(jù)文件分割符,默認為空格
    set part "\ "
    # 過濾關鍵字
    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.log
    match_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 $hostfile
    close $cmdfile
    exit
