Help in running a script after a particular time
Unix Gurus,

I have a requirement where the shell script needs to do specific tasks after certain period of time.

Daily we receive few files in a particular folder. The script does the file renaming, pass parameters to run some web services and pushes to remote FTP location.

But my requirement is to run the script 30 mins after the first file arrived. How to check and add that condition?

For example the 10 files start arriving from 10.00 AM. When I run the script it should get the earliest file saved time and do all the tasks 30 minutes later.
Basically it need to keep on checking the condition whether the time is +30mins of the first file saved time.

Note that the folder will always be empty after the script is run and hence there will be no expired time or overlap.

Please help.

Thanks in advance.

nqs2pbs

nqs2pbs(1B)								PBS							       nqs2pbs(1B)

NAME

       nqs2pbs - convert NQS job scripts to PBS

SYNOPSIS

       nqs2pbs nqs_script [pbs_script]

DESCRIPTION

       This  utility  converts	a  existing NQS job script to work with PBS and NQS.  The existing script is copied and PBS directives, #PBS , are
       inserted prior to each NQS directive #QSUB or #@$ , in the original script.

       Certain NQS date specification and options are not supported by PBS.  A warning message will be displayed indicating the  problem  and  the
       line of the script on which it occurred.

       If  any	unrecognizable	NQS  directives  are encountered, an error message is displayed.  The new PBS script will be deleted if any errors
       occur.

OPERANDS

       nqs_script
	      Specifies the file name of the NQS script to convert.  This file is not changed.

       pbs_script
	      If specified, it is the name of the new PBS script.   If not specified, the new file name is nqs_script.new .

NOTES

       Converting NQS date specifications to the PBS form may result in a warning message and an incompleted converted date.  PBS does not support
       date  specifications  of  "today",  "tomorrow", or the name of the days of the week such as "Monday".  If any of these are encountered in a
       script, the PBS specification will contain only the time portion of the NQS specification, i.e. #PBS -a hhmm[.ss].   It is  suggested  that
       you specify the execution time on the qsub command line rather than in the script.

       Note that PBS will interpret a time specification without a date in the following way:

       -  If the time specified has not yet been reached, the job will become eligible to run at that time today.

       -  If the specified time has already passed when the job is submitted, the job will become eligible to run at that time tomorrow.

       PBS does not support time zone identifiers.  All times are taken as local time.
