after finding the IP_ADD from this I have to write into a text file and later i will intialize with domain names from command prompt.
please help me to write a script.
1: how to find IP_add from the files present in the below 3 applications
2:after finding how to write into a text file ie redirect
3:how to intialize doman names from command prompt to that IP_add which written in text file.
For the 1st and 2nd item maybe this works:

Code:
find . -type f | xargs grep '[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*'| sed 's#.* \([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\).*#\1#'

gives the names of the files which includes any IP address (if you only look for a specific IP then you should give it there).

DH_INSTALLDEB(1)						     Debhelper							  DH_INSTALLDEB(1)

NAME
dh_installdeb - install files into the DEBIAN directory SYNOPSIS
dh_installdeb [debhelperoptions] DESCRIPTION
dh_installdeb is a debhelper program that is responsible for installing files into the DEBIAN directories in package build directories with the correct permissions. FILES
package.postinst package.preinst package.postrm package.prerm These maintainer scripts are installed into the DEBIAN directory. Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands. package.triggers package.shlibs These control files are installed into the DEBIAN directory. Note that package.shlibs is only installed in compat level 9 and earlier. In compat 10, please use dh_makeshlibs(1). package.conffiles This control file will be installed into the DEBIAN directory. In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this program, so there is no need to list them manually here. package.maintscript Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters. However, the "maint-script-parameters" should not be included as debhelper will add those automatically. Example: # Correct rm_conffile /etc/obsolete.conf 0.2~ foo # INCORRECT rm_conffile /etc/obsolete.conf 0.2~ foo -- "$@" In compat 10 or later, any shell metacharacters will be escaped, so arbitrary shell code cannot be inserted here. For example, a line such as "mv_conffile /etc/oldconffile /etc/newconffile" will insert maintainer script snippets into all maintainer scripts sufficient to move that conffile. It was also the intention to escape shell metacharacters in previous compat levels. However, it did not work properly and as such it was possible to embed arbitrary shell code in earlier compat levels. The dh_installdeb tool will do some basic validation of some of the commands listed in this file to catch common mistakes. The validation is enabled as a warning since compat 10 and as a hard error in compat 12. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
