I would like to print only the following output :

Code:
    elapsed

       0.00 
     239.91 
       0.00

     239.91 


    elapsed 
 ---------- 
       0.00 
       0.00 
       0.59 
 ---------- 
       0.59

I tryied :

Code:
cat filename.txt | awk '{print $4} '

But its not enough since i get all the output under column 4.

Thanks

dapptrace(1m)							   USER COMMANDS						     dapptrace(1m)

NAME
dapptrace - trace user and library function usage. Uses DTrace. SYNOPSIS
dapptrace [-acdeFlhoU] [-u lib] { -p PID | command } DESCRIPTION
dapptrace prints details on user and library function calls. By default it traces user functions only, options can be used to trace library activity. Of particular interest is the elapsed times and on cpu times, which can identify both function calls that are slow to complete, and those which are consuming CPU cycles. Since this uses DTrace, only users with root privileges can run this command. OPTIONS
-a print all details -b bufsize dynamic variable buffer size. Increase this if you notice dynamic variable drop errors. The default is "4m" for 4 megabytes per CPU. -c print function call counts -d print relative timestamps, us -e print elapsed times, us -F print flow indentation -l force printing of pid/lwpid per line -o print on-cpu times, us -p PID examine this PID -u lib trace this library instead -U trace all library and user functions EXAMPLES
run and examine the "df -h" command, # dapptrace df -h examine PID 1871, # dapptrace -p 1871 print using flow indents, # dapptrace -Fp 1871 print elapsed and CPU times, # dapptrace -eop 1871 FIELDS
PID/LWPID Process ID / Lightweight Process ID RELATIVE relative timestamps to the start of the thread, us (microseconds) ELAPSD elapsed time for this system call, us CPU on-cpu time for this system call, us CALL(args) function call name, with some arguments in hexadecimal DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver- bose descriptions explaining the output. EXIT
dapptrace will run forever until Ctrl-C is hit, or if a command was executed dapptrace will finish when the command ends. AUTHOR
