Help needed with File Watcher script
Hi all,
I am writing a script to do the following:
1) Check if there are any new <csv> files (in abc directory) to process
2) If there is new file, then perform some operation on that file.
3) Move it to a different location(after step2 is successful)
4) Do further processing on the file

Problem is that there can be either one or more <csv> files that will be available in this directory.
All the above steps need to be performed on each new file.

Not sure how i could do this on multiple files

This is how i wrote the script...The script is not coming out of the loop when running this...

Code:
while true
do
  for file in *.csv;
    do
     #Some operation 
   mv $file /xxx/yyy
   #some operation
   done
  sleep 10
  done

PLEASE HELP!!!!!
Thanks in Advance!!!

dh_installdebconf

DH_INSTALLDEBCONF(1)						     Debhelper						      DH_INSTALLDEBCONF(1)

NAME

       dh_installdebconf - install files used by debconf in package build directories

SYNOPSIS

       dh_installdebconf [debhelperoptions] [-n] [--params]

DESCRIPTION

       dh_installdebconf is a debhelper program that is responsible for installing files used by debconf into package build directories.

       It also automatically generates the postrm commands needed to interface with debconf. The commands are added to the maintainer scripts by
       dh_installdeb. See dh_installdeb(1) for an explanation of how that works.

       Note that if you use debconf, your package probably needs to depend on it (it will be added to ${misc:Depends} by this program).

       Note that for your config script to be called by dpkg, your postinst needs to source debconf's confmodule. dh_installdebconf does not
       install this statement into the postinst automatically as it is too hard to do it right.

FILES

       debian/package.config
	   This is the debconf config script, and is installed into the DEBIAN directory in the package build directory.

	   Inside the script, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.

       debian/package.templates
	   This is the debconf templates file, and is installed into the DEBIAN directory in the package build directory.

       debian/po/
	   If this directory is present, this program will automatically use po2debconf(1) to generate merged templates files that include the
	   translations from there.

	   For this to work, your package should build-depend on po-debconf.

OPTIONS

       -n, --no-scripts
	   Do not modify postrm script.

       -- params
	   Pass the params to po2debconf.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
