    Hi all,
    I have a script which can check server certificate expiry and get result how many days left.
    (=script download cert, save to file,convert and check date)
    Problem is that I have a lot of servers to check.
    Is here any way how rewrite code to load server’s IPs from text file? For example: line1 in server.txt: “some_description some_hostname IP_address_port”; Line2: same structure, different values. Always separate by “gap”. I need load just Ip_address_port from end of each line to check expiry for every server(every line) in servers.txt
    Can I do this with Split function or some simmilar? How put this into code?

    Other question is, when script find certificate with specify conditions, 20 days left to expiry or cert is expired eg., if is possible write line to other file (output.tx) with name of certificate (load CN from txt file?) and with line from server.txt ? I mean main output from script will be output.txt where I can see which certificates will expiry and when or which certificates are expired already.

    Thanks for suggestions!
