I have a large file where I want to extract the data by using awk script. I have made a small sample of the input data. I have in the awk script two condition . The first one is to collect the initial time and the second one to collect the end time. I stored the difference between (Time=end-start) in an array. However, when I'm trying to loop through the array to print the results, I'm not getting the difference correct. It seems the code storing the end time in the Time array instead of the difference.
here is the sample ;
and here is my code:
any suggestions what is the problem ???
Split usage is wrong
from gnu
Divide string into pieces separated by fieldsep and store the pieces in array and the separator strings in the seps array. The first piece is stored in array[1], the second piece in array[2], and so forth. The string value of the third argument, fieldsep, is a regexp describing where to split string (much as FS can be a regexp describing where to split input records; see Regexp Field Splitting). If fieldsep is omitted, the value of FS is used. split() returns the number of elements created. seps is a gawk extension with seps[i] being the separator string between array[i] and array[i+1]. If fieldsep is a single space then any leading whitespace goes into seps[0] and any trailing whitespace goes into seps[n] where n is the return value of split() (that is, the number of elements in array).
The split() function splits strings into pieces in a manner similar to the way input lines are split into fields. For example:
splits the string ‘cul-de-sac' into three fields using ‘-' as the separator. It sets the contents of the array a as follows:
and sets the contents of the array seps as follows:
