Could someone help in writing a shell script to monitor different cron jobs in crontab. As everyone knows different cron jobs run at different time I want to capture following things in ".csv" format:



  1. Script Name

  2. Scheduled times

  3. Next scheduled time

  4. Last Run time.

  5. Did the script ended successfully or it had an error after executing (Success/Fail).

I have certain limitations:




  1. syslog is not printing all the debug logs.

  2. Can't edit crontab.

I have logs which are directed which could be used.




shell-script cron logs

    Unless you have root access this is next to impossible because the necessary information is not available to non- root users. If you do have root you can edit crontab (technically, if not administratively).

Given the criteria you have specified this is not possible.



The necessary information is not available to non- root users. If you do have root you can edit crontab (technically, if not administratively) or change the flags used to run from, or read the cron log files.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
