@methyl this is a perf test suite of scripts and this "test" is to simulate Teradata, and network performance to the ETL box.
So currently have a script to run X predefined queries for Y minutes. Queries are re-submitted after they complete until Y minutes is up. Any running at this point stay running and have to be manually forced off. So am trying to re-code this process.
The reports are then generated from the number of queries run, run time for each, a seperate report is done from the log tables in the database. All this is then put in a report database available to managers after any major changes.
Think the solution is going to be pipe the rows to awk, generate the print statement into a temp file, (export NUMROWS=402) and then run that file to get that figure. bit more hassle but easy to implement. :-)

Hello all,
How do I start a background process and save the process id to a file on my system. For example %wait 5 & will execute and print the process id. I can't figure out how to get it to a file. I've tried: > filename 0>filename 1>filename.
Any assistance is most appreciated.
Thanks,

sleep
SLEEP(1) BSD General Commands Manual SLEEP(1)NAME
sleep -- suspend execution for an interval of time
SYNOPSIS
sleep seconds
DESCRIPTION
The sleep command suspends execution for a minimum of seconds.
If the sleep command receives a signal, it takes the standard action.
IMPLEMENTATION NOTES
The SIGALRM signal is not handled specially by this implementation.
The sleep command will accept and honor a non-integer number of specified seconds (with a '.' character as a decimal point). This is a non-
portable extension, and its use will nearly guarantee that a shell script will not execute properly on another system.
EXAMPLES
To schedule the execution of a command for x number seconds later (with csh(1)):
(sleep 1800; sh command_file >& errors)&
This incantation would wait a half hour before running the script command_file. (See the at(1) utility.)
To reiteratively run a command (with the csh(1)):
while (1)
if (! -r zzz.rawdata) then
sleep 300
else
foreach i (`ls *.rawdata`)
sleep 70
awk -f collapse_data $i >> results
end
break
endif
end
The scenario for a script such as this might be: a program currently running is taking longer than expected to process a series of files, and
it would be nice to have another program start processing the files created by the first program as soon as it is finished (when zzz.rawdata
is created). The script checks every five minutes for the file zzz.rawdata, when the file is found, then another portion processing is done
courteously by sleeping for 70 seconds in between each awk job.
DIAGNOSTICS
The sleep utility exits 0 on success, and >0 if an error occurs.
SEE ALSO nanosleep(2), sleep(3)STANDARDS
The sleep command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
HISTORY
A sleep command appeared in Version 4 AT&T UNIX.
BSD April 18, 1994 BSD
