Shell script to find the run time based on log entries?
Shell script to find the run time based on log entries?
Below is the log files content updated when the script test.sh runs. I would like to calculte the difference between first update time stamp and last update time stamp to find the run time of the script. The below log file shows the first update as 16:50 and last update 17:42.


Is there any way to find the run time with the difference between first update line and last update line.

Code:
l106:/opt/PATH… cat SETCSH_20101030_205037.log

Hi,

Try this 'awk' solution:
Code:
$ cat script.awk
BEGIN {
  FS = "[ ,]"; 
} 

NR==1 { 
  datef = $1; 
  timef = $2; 
} 

END { 
  datet = $1; 
  timet = $2;

  split(datef, arrDatef, "-"); 
  split(datet, arrDatet, "-"); 
  split(timef, arrTimef, ":"); 
  split(timet, arrTimet, ":");
  utcDateTimeF = mktime(arrDatef[1] " " arrDatef[2] " " arrDatef[3] " " arrTimef[1] " " arrTimef[2] " " arrTimef[3]);
  utcDateTimeT = mktime(arrDatet[1] " " arrDatet[2] " " arrDatet[3] " " arrTimet[1] " " arrTimet[2] " " arrTimet[3]);
  printf "%s\n", strftime("%H:%M:%S", utcDateTimeT - utcDateTimeF, 1);
}

Code:
$ cat infile
