How to check the user input to be valid using shell script?
The valid input is in the format like as follows.

2. ensure the r, w, x are in the correct order.

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.
