我正在製作一個將通過打印機服務器運行的程序，並取消掛起的作業。截至目前它輸出的一切，我想要做的是排除root：從prt_jobs中排除根目錄

#<= No more root

有沒有一種方法，我可以輸出相同的信息，但排除根作業？

來源：

#!/local/usr/bin/ruby 

require 'rubygems' 
require 'net/ssh' 
require 'etc'   

class PrintJobs 

    HOST = '<server here>' #<= Left blank for security 
    USERNAME = Etc.getlogin 
    PASSWORD = nil 

    def scan_for_jobs 
    check_jobs = Net::SSH.start(HOST, USERNAME, :password => PASSWORD) do |ssh| 
     cmd = "prt_jobs" 
     res = ssh.exec!(cmd) 
     puts res 
    end 
    end 
end 

test = PrintJobs.new 
test.scan_for_jobs

如果答案對您有幫助，請接受。 –

@WandMaker沒有先生。 – Bam

您可以通過下面的代碼擺脫多餘線條：

res = ssh.exec!(cmd) 
    res = res.split("\n").reject {|line| line.match(/\s+root\s+/)}.join("\n") 
    puts res

的exec!結果發出了SSH一個包含命令的輸出字符串。因此，我們需要通過換行來拆分它，並遍歷數組以拒絕包含root的行，並使用新行重新加入數組。
