小编Spr*_*ips的帖子

我有一个方便的脚本,可以返回将在7天后过期或已过期的帐户.我想允许它在多个主机上运行,而不是将脚本放在每个单独的主机上,我添加for loop了ssh $SERVER >> EOF部件,但它只是从运行脚本的系统运行命令.

我相信错误是有的,ssh $SERVER >> EOF但我不确定语法看起来是否正确.

#!/bin/bash

for SERVER in `cat /lists/testlist`
do
  echo $SERVER

  ssh $SERVER >> EOF
    sudo cat /etc/shadow | cut -d: -f1,8 | sed /:$/d > /tmp/expirelist.txt
    totalaccounts=`sudo cat /tmp/expirelist.txt | wc -l`
    for((i=1; i<=$totalaccounts; i++ ))
    do
      tuserval=`sudo head -n $i /tmp/expirelist.txt | tail -n 1`
      username=`sudo echo $tuserval | cut -f1 -d:`
      userexp=`sudo echo $tuserval | cut -f2 -d:`
      userexpireinseconds=$(( $userexp * 86400 ))
      todaystime=`date …

type bool_exp =
    TT
  | FF
  | Var of string
  | And of bool_exp * bool_exp
  | Not of bool_exp ;;

 eval : bool_exp -> (string -> bool) -> bool

我正在尝试编写一个名为的求值函数eval.我是OCaml的新手并不习惯语法.我在哪里可以写这篇文章？

我需要帮助才能在我的Debian 7.2系统上安装emacs.我查看了许多其他表单,无法安装emacs.

我已经尝试运行"sudo apt-get install emacs","sudo apt-get install emacs23",以及任何其他类型emacs的方式.

我也尝试过返回404错误.
