nawk time substracting
Nawk ‘BEGIN {printf “0t%d=Y\n”,srand () -1800}' | adb
I know that printf is printing the value in %d which is for a day of the month and subtracting the value by -1800 (30 minutes).
So if date is 14:25:45 subtracting from 1800 then time will equal to 13:55:45
I also know that srand () is function that is used to set a new seed for the random number generator.
However I don't know what is 0t doing? What is for?Is | adb - debugging the code?
Also what I want is to store the workout value in variable (so every time I run the script it subtracts 30 minutes from current time and stores the value in variable). So I can use the variable in loop which will check all the logs created 30 minutes ago. I can't use gawk
Any help will be greatly appreciated
Thank you all
