| 标题 | expect实现批量修改linux密码脚本分享 |
| 内容 | 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: 代码如下: #!/usr/bin/expect if { $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.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 |
