Time duration from one command to another
 

Hi. I have made a shell script as below to find that how much time is taking between one command to another.
echo weekly backup started `date '+%Y-%m-%d/%k-%M'` > /var/log/backup/weekly.log
tar -cjvf something.tar.bz2 /directory
echo weekly backup completed `date '+%Y-%m-%d/%k-%M'` >> /var/log/backup/weekly.log
If I cat the content of /var/log/backup/weekly.log file the actual time is taken 5 hours 30 minutes for compressing and given 38GB *.bz2 file.
But for sending that 38GB *.bz2 file to some other server it is taking around only 25 minutes. for that the shell script as below
echo weekly backup sending to someserver `date '+%Y-%m-%d/%k-%M'` > /var/log/backup/nfsweekly.log
scp /directory/*.bz2 root@IP_Addr:/directory
echo weekly backup sent to someserver `date '+%Y-%m-%d/%k-%M'` >> /var/log/backup/nfsweekly.log
But I found only 29GB size in another server instead of 38GB. So there is a suspection of 2nd shell script, becuase if I realy use scp command insted of script it will take more than hour. In another server lot of free space is there where I am sending *.bz2 file. Although the file size is only 29GB instead of 38GB. So how can I made changes that only then that 3rd command(echo weekly backup sent to someserver `date '+%Y-%m-%d/%k-%M'` >> /var/log/backup/nfsweekly.log) should execute when 2nd(scp /directory/*.bz2 root@IP_Addr:/directory) command is successfully completed.

Sorry but I've some difficulty to get what you are doing.

1. You create a tar.bz2 file. (which is one file only right? or you split the file?)
2. Then, I lost you... :(


Can you please clarify your issue?

Thanks,
Angel.

Please number your step so it will be easier to follow you.

Can time commands separately
 

You can always use the time command to get the exact time taken by a command:
This would output the time given to compress your directory.
Just prepend time before the command you want to clock...

If I cat the content of /var/log/backup/weekly.log file the actual time is taken 5 hours 30 minutes for compressing and given 38GB *.bz2 file.
But for sending that 38GB *.bz2 file to some other server it is taking around only 25 minutes. for that the shell script as below
If you are posting scripts longer than one line please bracket them using the code ... /code surrounded by square brackets. That makes things easier to read as you can see from the above example.
