I'm not sure exactly what you mean but I think I will take a guess.

To be able to find out how long it takes to complete the command you would use the time command as a prefix to your process. Here is an example of me checking how long it takes to backup the directories /root and /home to the file /backup.tgz

[root@rpmdev.pantek.com /]# time tar -zcf backup.tgz root home

real 0m46.977s
user 0m14.625s
sys 0m10.857s
[root@rpmdev.pantek.com /]#

hi kentyler:-
what i mean
1- i have some script run at scheduler time
2- this script take a duration time
3- this script put log into scecific folder (the log doesn't include start time and the end time)

what i need if i want to know the duration time for each script what can i do

You can just do what kentyler rightly suggested, i.e. prefixing the script by the time command.

If you would like to have the output in a seperate file you would do this:

/usr/bin/time -o timescripttakes.txt scriptname.sh

To append the time it takes to execute your script to your current scripts log you would use the following

/usr/bin/time -a -o scriptoutputlog.txt scriptname.sh

Note that the builtin version of time without full path does not accept options.

hi kentyler:-
i am new user for unix i am also using open solaris 5.11 could you please explain

really i can't understand

real 0m46.977s
user 0m14.625s
sys 0m10.857s
what is this output

The first line (real 0m46.877s) is precisely telling the duration time it took too execute the command (tar ...). It means the tar took 0 minute, 46 seconds and 977 thousandths of seconds.
The remaining two lines relate to how the CPU was loaded by the tar command.
