在列中保存格式输出 [grep、sed、awk 或 ?]答案

【问题标题】：Saved format output in columns [grep, sed, awk or ?]在列中保存格式输出 [grep、sed、awk 或 ?]
【发布时间】：2015-06-04 07:43:57
【问题描述】：

我创建了一个可以远程登录到多个 +200 交换机的 Expect 脚本文件。

我的代码：

#!/usr/bin/expect -f
#Slurp up the input file
set fp [open "ip.txt" r]
# To avoid empty lines, 'nonewline' flag is used
set file_data [read -nonewline $fp]
close $fp
set prompt ">"
log_file -noappend switch_port_status.txt
foreach ip [split $file_data "\n"] {
puts "Switch $ip Interface Status"
spawn telnet $ip
expect "Username:"
send "MyUsername\r"
expect "assword:"
send "MyPassword\r"
expect $prompt
# To avoid sending 'Enter' key on huge configurations
send "show ip int br\r"
expect {
-ex "--More--" { send -- " "; exp_continue }
"*>" { send "exit\r" }
}
#expect $prompt
set timeout 1; # Reverting to default timeout
# Sending 'exit' at global level prompt will close the connection
expect eof

对于 Expect Script "log_file -noappend switch_port_status.txt"，我保存了一个输出文件如下：

这可以用 Linux 中的 awk/sed/grep 实用程序来完成吗？

提前感谢您的帮助。

【问题讨论】：

非常详尽，但对于简单重新格式化来说有点庞大（信息量）
您的输出是完整的或过滤的，例如没有退出 192.168.0.2 但对于其他井，....换句话说，您的标准是什么来重新格式化它？跨度>
输出是满的，它会自动像这样输出。如果我们假设有一个出口，我们应该省略下面的词：『正在尝试 IP 地址......连接到 IP 地址（IP 地址）。转义字符是 '^]'。仅限授权访问如果您不是授权用户，该系统是公司名称的财产立即断开连接！用户访问验证用户名：MyUsername 密码：』『>show ip int br』『>exit Connection closed by foreign host.』
只有 IP、主机名、接口和状态才能获得我的帖子中提到的输出文件条件。我可以编辑期望脚本以将输出文件转换为上面所需的格式输出吗？还是我需要打开另一个 perl 文件？

标签： regex perl awk sed expect

【解决方案1】：

至于 perl 的实现，我建议这样做：

#!/usr/bin/perl -nl

print "\n$1" if (/Connected to (\S+)/);
if ($line_num = (/^(\S+?)(?:>|#)show ip int br/ ... /^.*?(?:>|#)/)) {
    if ($line_num == 1) {
        print $1;
    } elsif ($line_num > 2 && /^(\S+)\s+\S+\s+\S+\s+\S+\s+(.*)\s+\S+$/)  {
        print "$1;$2";
    } elsif ($line_num > 2 && /^\s*$/)  {   # retian empty lines after 
                                            # 'show ip int br' if there are any
        print;
    }
}

用法：squeeze.pl your_swicth_status_script_output.txt 其中squeeze.pl 是上述脚本的名称。

【讨论】：

我已更改脚本以考虑各种提示字符并可能缺少“退出”命令
您提供的脚本可以工作，但还有一个问题。当我使用发布的脚本副本返回交换机时，我可以使用您提供的 perl 获得预期的结果，如图所示。但是，如果我使用相同的 perl 在上一个开关中运行输出文件，则在“show ip interface brief”之后这些行不会分开。我尝试编辑但失败，请建议我如何进行修改。非常感谢。
【格式为我的帖子】：（i109.photobucket.com/albums/n73/CyberLuk/…）【脚本工作】：（i109.photobucket.com/albums/n73/CyberLuk/…）【原始格式进入开关】：（i109.photobucket.com/albums/n73/CyberLuk/…）【只显示IP&主机名】：（ i109.photobucket.com/albums/n73/CyberLuk/…) [原始输出文件下载链接]: (drive.google.com/file/d/0B0tUlNEULMxqZkt2WXZwcnVWcWc/…)
嗨@DannyLuk！如果有空行，您需要在接口表中保留空行吗？如果是这样，请使用答案中的更新脚本版本。否则请您详细说明您的要求吗？
非常感谢！我的帖子中所需的输出格式。当我使用我发布的脚本副本返回交换机时，这是我的帖子格式问题。不使用“$”解决的问题。

【解决方案2】：

@Dmitry Egorov 非常感谢！
我的帖子中所需的输出格式。当我使用我发布的脚本副本返回交换机时，这是我的帖子格式问题。不使用“$”解决的问题。

你之前的代码：

#!/usr/bin/perl -nl

print "\n$1" if (/Connected to (\S+)/);
if ($line_num = (/^(\S+?)(?:>|#)show ip int br/ ... /^.*?(?:>|#)/)) {
    if ($line_num == 1) {
        print $1;
    } elsif ($line_num > 2 && /^(\S+)\s+\S+\s+\S+\s+\S+\s+(.*)\s+\S+$/) {
        print "$1;$2";
    }
}

我当前的代码：

#!/usr/bin/perl -nl

print "\n$1" if (/Connected to (\S+)/);
if ($line_num = (/^(\S+?)(?:>|#)show ip int br/ ... /^.*?(?:>|#)/)) {
    if ($line_num == 1) {
        print $1;
    } elsif ($line_num > 2 && /^(\S+)\s+\S+\s+\S+\s+\S+\s+(.*)\s+\S+/)  {
        print "$1;$2";
    }
}
