So, maybe that long of a sleep is giving the CPU fits? when I had this problem before, and wasn't using a sleep command, I solved it using sleep 1 which gave the CPU plenty of time to catch up on other things.
I can't imagine a company setting a policy against using one of the most powerful friends a sysadmin has. Amazing what people do.... But, I've an open mind. Convince me that prohibiting the use of cron is a good idea.
eg: If I execute an example tail statement to put rows from one file to another, it truncates some of the data.
/carrier>wc -l IntIndA.txt
1918 IntIndA.txt
/carrier>tail -1918 IntIndA.txt > test
/carrier>wc -l test
132 test
The tail command should copy 1918 rows to test file instead of... (4 Replies)

sleep
sleep(3) Library Functions Manual sleep(3)Name
sleep - suspend execution for interval
Syntax
unsigned
sleep(seconds)
unsigned seconds;
Description
The current process is suspended from execution for the number of seconds specified by the argument. The actual suspension time may be up
to 1 second less than that requested, because scheduled wakeups occur at fixed 1-second intervals, and an arbitrary amount longer because
of other activity in the system.
The routine is implemented by setting an interval timer and pausing until it occurs. The previous state of this timer is saved and
restored. If the sleep time exceeds the time to the expiration of the previous timer, the process sleeps only until the signal would have
occurred, and the signal is sent 1 second later.
Return Values
The value returned by is the unslept amount(the requested time minus the time actually slept). This return value may be non-zero in cases
where the caller had an alarm set to go off earlier than the end of the requested time, or where was interrupted due to a caught signal(see
ENVIRONMENT below).
Environment
POSIX
SYSTEM_FIVE
When your program is compiled in POSIX or System V mode, the will be terminated by any caught signal. The function will return following
execution of the signal's catching routine.
