However, it is worth noting that the date command can also be used to set the time on a computer. The syntax is as follows for the GNU/date and BSD/date command: date +FORMAT date +'FORMAT' date +'FORMATFORMAT' date +'FORMAT-FORMAT' An operand with a leading plus ( +) sign signals a user-defined format string which specifies the format in which to display the date and time. The date command isn’t used as much to set time any more, since most systems rely on a Network Time Protocol (NTP) server to supply date and time information. To grab the date formatted as such, the following command can be used:ĭate -j -f “%a %b %d %T %Z %Y” “`date`” “+%s” Some of you will be using log analyzers that depend, for example, on unix epoch time. Now, in our shell script we can create files, add lines to files, etc, with the shortened date stamp. It is currently not possible to manipulate EFI variables from within a running guest (e.g. Here we’re going to grab the current system date from ESX, OS X or Linux (or whatever OSen really) and then use a variable, currentdate, to put that date, formatted into a pretty standard format, YYYYMMDD:Ĭurrentdate=`date ”+%c%m%d” | awk ‘’` The only NVRAM variable that appears to be settable is boot-args. In a script this can choose fairly challenging, especially in cases where you just need the date stamp without the time and time zone, etc. Print('address: ' + ni.At a terminal prompt, it is really straight forward to grab the date, simply use the date command, with no arguments and you will get something similar to the following, including the day, date, time (with seconds), time zone and year: Yet ANOTHER option if you just want to enumerate over up interfaces, since nobody seems to be able to understand exactly what you want: import netifaces as ni

If all you want is the IP of the up and outbound interface, this works. #define AF_INET 2 /* Internet IP Protocol */ Theres also live online events, interactive content, certification prep materials, and more. The numbers used to index protocols are from /usr/include/linux/socket.h (in Linux).

In this file, you can define all the build logic and add build dependencies. It operates using a build rule file in XML format. It supports multiple platforms like Windows, Linux, and Mac OS X. 1.1- What is ANT Script First of all, you should know that ANT is a universal build tool created in Java. netifaces.AF_INET, and whose values are a list of addresses in that family that are attached to the network interface.' Ant script to change system date and time. 'Obtain information about the specified network interface. Returns a dict whose keys are equal to the address family constants, e.g. Ip addr | grep 'state UP' -A2 | tail -n1 | awk '
