SLEEP(1) BSD General Commands Manual SLEEP(1)NAME
sleep -- suspend execution for an interval of time
The sleep command suspends execution for a minimum of seconds.
If the sleep command receives a signal, it takes the standard action. When the SIGINFO signal is received, the estimate of the amount of
seconds left to sleep is printed on the standard output.
The SIGALRM signal is not handled specially by this implementation.
The sleep command allows and honors a non-integer number of seconds to sleep in any form acceptable by strtod(3). This is a non-portable
extension, and its use will nearly guarantee that a shell script will not execute properly on another system.
The sleep utility exits 0 on success, and >0 if an error occurs.
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)):
if (! -r zzz.rawdata) then
foreach i (`ls *.rawdata`)
awk -f collapse_data $i >> results
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.
SEE ALSO nanosleep(2), sleep(3)STANDARDS
The sleep command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
A sleep command appeared in Version 4 AT&T UNIX.
