The question does not have to be directly related to Linux and any language is fair game.

I am learning Awk and unix programming. I have a file of data, the first column in time. I have parsed the original files into multiple files each containing 1 cycle. I want to normalise the time in each file so that each file starts from time 0 s. Obviously the first cycle starts from 0 s any way.
I have many cycle files to do so i don't want to do this manualy. Eventually this will all be put in a loop so that i can do all the files with the name cycle_data_* in a given folder.
Using Awk how do I set "t_norm" to be the value of $1 of line 1 when it is processing all lines in the file in the below script?
I have also tried doing this another way, whereby I firstly create a file (file_init_time.txt) with the value which needs to be subtracted from the value $1 of each line in the file. However, i am struggling passing values between the awk commands. I have tried different ways but can't get it to work either.
