Shell Programming and Scripting

Hi All,

I have a file which contains two lines as below :

Thu Mar 18 19:23:46 EDT 2010: exeStoredProc.sh (info) OSA_rule.bteq D031810.T190447 993210020
Thu Mar 18 19:47:03 EDT 2010: exeStoredProc.sh (info) rc=0


I need to calculate the difference between the highlighted time values. Is it possible to do in Unix. If so please let me know how can we do that.

Thanks,
Satya Ranjon

Take a look at this one:
https://www.unix.com/shell-programmin...e-solaris.html

And search for others. One thought to keep in mind is to convert each date/time to epoch time, then do your math.

Try this,

Code:

#!/bin/sh
time_start=`date +%s -d "$1"`
time_end=`date +%s -d "$2"`
diff_time=`expr $time_end - $time_start`
echo $diff_time;

Hi Nila,
How can i use it. I am getting the format as a input from a file and need to calculate the difference between the two time. Can u explain a bit.

Just I gave the code for handling the command line arguments in shell script. If you have the time value in separate variable, you can use your variable instead of "$1" and "$2" in my script.
