[Solved] Check for a file and keep waiting for 30 mins

Hi All!


I want to have a shell script that checks for a file in a particular folder and then if the file is not found it should wait for 30 minutes. Again check for the file, if it FOUND then successfuly exit the shell script stating the file is found. Else it should continue to wait.



Scenario:

> data/source

if a.txt is not found in data/source folder then wait for 30 minutes and then check again the folder data/source

if a.txt is found in data/source folder then exit the script stating that file found

COMMAND-NOT-FOUND(1)					    http://en.opensuse.org/Sco					      COMMAND-NOT-FOUND(1)

NAME
command-not-found - A command-not-found handler SYNOPSIS
command-not-found {binary_name} {repository} ARGUMENTS
The following arguments are required: binary_name The name of binary you are looking for. repository The name of repository for search. For most cases, use zypp DESCRIPTION
command-not-found handler is designed to tell users which package contains a missing command. The handler is integrated to bash(1) and zsh(1) shells and is not necessary to call it directly. Just type a name of the command in your favourite shell and you'll get a result. If you consider c-n-f handler useless, just add unset command_not_found_handle to your profile or remove the command-not-found package. Handler doesn't call the command-not-found binary directly, it only prints info about it. If you want to invoke it automatically, just add export COMMAND_NOT_FOUND_AUTO=1 to your bash profile. EXAMPLE
: NORMAL USAGE For example you want to try blender, because you have heard that is an amazing program. So just type blender in shell: $ blender You get the following output: The program 'blender' can be found in the following package: * blender [ path: /usr/bin/blender, repository: zypp (openSUSE 11.1-0) ] Try installing with: sudo zypper install blender bash: blender: command not found SEE ALSO
