我有一个脚本会检查我们的服务器是否有使用net/ssh挂起的打印作业。
现在我要做的是使用脚本输出的job ID（包含所有数字的第3列）并取消作业（我知道我将如何取消）在Ruby中，有没有办法使用输出数字作为输入？
来源：
#!/usr/local/bin/ruby
require 'rubygems'
require 'net/ssh'
require 'etc'
require 'adfitech/mail'
class PrintJobs
HOST = ARGV[0]
USERNAME = Etc.getlogin
PASSWORD = nil
def scan_for_jobs
check_jobs = Net::SSH.start(HOST, USERNAME, :password => PASSWORD) do |ssh|
cmd = "prt_jobs"
info = ssh.exec!(cmd)
res = info.split("\n").reject {|line| line.match(/\s+2016\s+/)}.join("\n")
puts res
print "Kill jobs: "
input = STDIN.gets.chomp.upcase
if input == "YES"
kill_jobs(check_jobs, res)
else
exit 1
end
end
end
def kill_jobs(check_jobs, res)
puts "Loading jobs in kill que.."
# <= Here output digits
end
end
test = PrintJobs.new
test.scan_for_jobs
输出：
#3rd column with the digits is the job ID

答案 0 :(得分：1)
你的问题很模糊，但我想我明白了，所以我会捅它。我想你想解析那个输出并得到工作ID，对吧？我假设工作ID在该输出的第3列中，让我们摘录一下：
output = <<-HEREDOC
laser26-828837 kaj 1042432 Fri 21 Aug 2015 03:59:35 PM CDT
laser26-828982 leb 446464 Fri 21 Aug 2015 04:52:20 PM CDT
laser26-828983 leb 1042432 Fri 21 Aug 2015 04:52:20 PM CDT
HEREDOC
要从该字符串中获取所有Job IDS，我们可以映射每一行，将这些行按空格分开并获得第3项：
column = 2 # 3rd column
job_ids = output.lines.map { |line| line.split(/\s+/)[2] }
# => ["1042432", "446464", "1042432"]
希望有所帮助。
