Question

我需要從數組中刪除制表符空間，並將值與一個帶有字符串的數組值進行比較。

inspec> command("chage -l root").stdout.split("\n").flatten{|x| x.strip || x}
=> ["Last password change\t\t\t\t\t: Feb 27, 2017",
 "Password expires\t\t\t\t\t: May 28, 2017",
 "Password inactive\t\t\t\t\t: Apr 20, 2067",
 "Account expires\t\t\t\t\t\t: Nov 27, 2019",
 "Minimum number of days between password change\t\t: 0",
 "Maximum number of days between password change\t\t: 90",
 "Number of days of warning before password expires\t: 7"]
inspec> 

Answer 1

使用Array＃map和String＃gsub 。

因此，代碼將是：

command("chage -l root").stdout.split("\\n").flatten{|x| x.strip || x}.map{|x| x.gsub(/\\t/, '')}
