*Description:*
time runs the program COMMAND with any given arguments . When COMMAND finishes, time displays information about resources used by COMMAND (on the standard error output, by default). If COMMAND exits with non-zero status, time displays a warning message and the exit status. time can be used to track the real,system and user time of COMMAND. *Dependent Binaries:* - /usr/bin/time *Approach:* - Create a custom python script which will be given as input to time package. - This custom python script will record its own resource usage statistics in temporary file. - The time package is also made to store the resource usage statistics using its switches of the custom python script in another file. - The values in the above mentioned files are compared to verify the correct working of time. - A custom shell script is also made so that the real time given by the time can be confirmed. - This custom shell script has nothing except sleep command. - Switches to be tested : 1. time -p (lists real ,user and system time0 2. time -v(Outputs an elaborated resource usage statistics) *Test:* *time -p:* - Run time -p with custom shell script. - Confirm the "real time" output with that of argument to sleep in custom shell script. *time -v:* - Run time -v with custom python script. - Compare the values in two output files generated by the time and the custom python script. *Clean Up:* - Clean all the scripts/output files generated by the test -- *Regards,* *Paul Davies C* vivafoss.blogspot.com
