solaris cron

A few months ago, the Server OS was changed from Ubuntu 10.04 to CentOS 6.3. After wine is installed, you can run the shell script manually to run the specified exe program (the script is the same as that in Ubuntu ), therefore, the script is automatically run when crontab is modified. Recently, it was found that the exe was not automatically executed once (Dahan, which serves as a backup database and clearing outdated backup). So I immediately searched for the cause of the problem and prelimina

A cron expression has at least 6 (or possibly 7) time elements that have a space separation.In order of1 seconds (0~59)2 minutes (0~59)3 hours (0~23)4 Days (0~31)May (0~11)6 weeks (1~7 1=sun or Sun,mon,tue,wed,thu,fri,sat)7. Year (1970-2099)Each of these elements can be a value (such as 6), a continuous interval (9-12), a time interval (8-18/4) (/= every 4 hours), a list (1,3,5), and a wildcard character. Because the "date in the month" and "date in t

This little trick, though small, is very useful.I wrote a cron script, but every other day I found out that the cron script of yesterday was still running and didn't stop, there must be a program plugged in.But it takes a lot of time if I run again. What about this?The most need now is to know that the program is parked on that line of code. Using GDB:$sudo gdb-p14973(gdb) print (Char*) executor_globals.act

A few days ago the friend said his station consumes the cloud bean to be formidable, then sees the log to discover most is the visit cron.php. And then is not the intranet IP access, and also did not add monitoring and so on, it is estimated that the malicious visit by others. But feel that the modification of the name is also somewhat unsafe, the IP blacklist effect will not be very strong. Because IP can be changed at any time, so I added a piece of code to solve this problem. is to add a get

Crontrigger Crontriggers tend to be more useful than simpletrigger, if you need to base the concept on calendars, rather than simpletrigger a fully specified time interval, recurrence of the launch work schedule.Crontrigger, you can specify the trigger schedule such as "Every Friday noon", or "every weekday 9:30", or even "every 5 minutes, 9:00 and 10:00 per day, Monday mornings, Wednesday Fridays".Even so, as with Simpletrigger, Crontrigger owns the starttime specified timesheet when the specif

Use the-i option if you want to show the total number of I nodes in the file system, the number of idle I nodes, the number of I nodes that have been used, and the percentage of the I node that I used to use. For example, under Solaris, executable: Df-o I (note oh: I before "-", hehe) When there is less free space in the file system so that the efficiency of the file system is reduced, the following meas

How to make the cron send an error message know that if MAILTO is set, cron will send the task output to the specified mailbox. However, if you only want to receive an error alert email, that is, if the task is not sent during normal execution, but only when an error occurs, how can this problem be achieved? The method is simple. Specify the standard output of the task as/dev/null. MAILTO = mybox@gmail.com0
