Script check for file, alert if not there, and continue checking until file arrives
All,
Is there a way to keep checking for a file over and over again in the same script for an interval of time?

Ie

If [no file] {
mail -user
continue checking until file arrives
file arrives
tasks
exit

I don't want the script to run each time and email the user each time a file isn't there. So, I want it to continue checking the file until it arrives and only exit when the file shows up.

NAME

       away - terminal locking program

SYNOPSIS

       away [OPTIONS] message [...]

DESCRIPTION

       away  is a simple program that locks your terminal, checks for new mail in any given number of mailboxes, and lets other users know why you
       are inactive.

OPTIONS

       -c, --mail
	      Enable checking of mail.

       -C, --nomail
	      Disable checking of mail.

       -f, --rcfile=FILE
	      Specify an alternative configuration file instead of the default ~/.awayrc file.

       -F, --norcfile
	      Ignore user configuration file.

       -h, --help
	      Display help.

       -m, --message
	      Execute as the remainder of the command line, effectively stripping off the executable name and additional switches.

       -p, --persist
	      Continue checking for new mail as long as there is at least one mailbox that has not received new mail.

       -P, --nopersist
	      Stop checking mail if any mailbox is found to have new mail.

       -t, --time=SECONDS
	      Set the number of second that away sleeps before performing its background tasks.  Presently, the only  background  task	that  away
	      will perform is the checking of mailboxes.

       -T, --notime
	      Ignore any options to set the time interval and use the default number of seconds.

       -v, --version
	      Display version information.

FILES

       ~/.awayrc
	      Per user configuration file. See awayrc(5) for further details.

       /etc/pam.d/away
	      The Linux-PAM configuration file.
