Script should keep checking for availability of files.
Hi,
I want my script to check for availability of few files contineously for some time.
Lets say from 10:00 AM to 10:30 AM script should keep checking on a particular location for each file one by one. If all the files are available then only it should complete the next processing part, else it should keep checking for the availability of the file. and after 10.30 AM the script should run completely as all files are available and if still file is not available by 10.30 then log error in logfile, but script should run by this time as it crossed the threshold 10.30.
If files available at 10.10 AM then script should run complete by the same time and no need to wait till 10.30.
thanks
Amit

itruns(8) System Manager's Manual itruns(8)
NAME
itruns - set up files for use by the it command
SYNOPSIS
/sbin/itruns file [file...] in run-state [, file [file...] in run-state] [,...]
DESCRIPTION
The itruns program sets up scripts to be run by it(8). (These programs are typically used within system configuration and installation
scripts.) The itruns command searches for /sbin/it.d/bin/file. If itruns finds the file, it creates one or more symbolic links from
/sbin/it.d/run-state.d/file to /sbin/it.d/bin/file.
The run-state argument can be a single run state, or it can be two run states separated by either the word or or the word and. If two run
states are specified with the or keyword, itruns checks for (and creates, if necessary) a directory whose name combines both run states and
places a link in that directory so that the file will be executed when the it program detects either state. You can collapse two or-sepa-
rated states into a single expression; for example, 2 or 3 can be expressed as 23. If the and keyword is used, itruns checks for (and cre-
ates, if necessary) two separate directories and places a link in each of them so that either state triggers execution of the file indepen-
dently of the other state.
If two or more files are specified for a single run-state argument, links are created for all of the files as indicated by the run-state
argument.
If two or more combinations of files and run states are specified as comma-separated expressions, itruns treats each combination individu-
ally.
RESTRICTIONS
The itruns command must be executed from the root directory (/). The command finds only files that are located in the /sbin/it.d/bin direc-
tory.
EXAMPLES
This example sets up the doconfig script to be run when the system is booted to run state 2: itruns doconfig in 2 Either of the command
lines in this example sets up the doconfig and getdate scripts to be run when the system is booted to run state 2 or to run state 3: itruns
doconfig getdate in 2 or 3 itruns doconfig getdate in 23 This example sets up the doconfig script to be run when the system is booted to
run state 2 and again when the system comes to run state 3, the getdate script to be run only in run state 2, and the getsysname script to
be run only in run state 3: itruns doconfig in 2 and 3, getdate in 2, getsysname in 3
