Ruby腳本在Linux中管理進(jìn)程

在Linux中，可以使用Ruby腳本來管理進(jìn)程

1. 獲取進(jìn)程列表：

#!/usr/bin/env ruby

def get_process_list
  `ps aux`.split("\n").drop(1).map { |line| line.split }
end

process_list = get_process_list
process_list.each { |process| puts process.join("\t") }

2. 根據(jù)進(jìn)程名篩選進(jìn)程：

#!/usr/bin/env ruby

def get_process_list(process_name)
  `ps aux | grep #{process_name}`.split("\n").drop(1).map { |line| line.split }
end

process_name = "ruby"
process_list = get_process_list(process_name)
process_list.each { |process| puts process.join("\t") }

3. 殺死指定進(jìn)程：

#!/usr/bin/env ruby

def kill_process(pid)
  system("kill -9 #{pid}")
end

pid = 12345
result = kill_process(pid)
puts result ? "Process killed successfully" : "Failed to kill the process"

4. 殺死所有匹配的進(jìn)程：

#!/usr/bin/env ruby

def get_process_list(process_name)
  `ps aux | grep #{process_name}`.split("\n").drop(1).map { |line| line.split }
end

def kill_process(pid)
  system("kill -9 #{pid}")
end

process_name = "ruby"
process_list = get_process_list(process_name)
process_list.each do |process|
  pid = process[1].to_i
  kill_process(pid)
end

請(qǐng)注意，這些示例僅適用于Linux系統(tǒng)。在運(yùn)行這些腳本之前，請(qǐng)確保已經(jīng)安裝了Ruby并將其添加到系統(tǒng)路徑中。同時(shí)，根據(jù)實(shí)際需求修改腳本中的進(jìn)程名和PID。
