If the scripts (short) name is "GEN_POSCAR", then it is a file in directory "/scratch/scratchdirs/saleheen/Scripts/My-scripts". The full name would be "/scratch/scratchdirs/saleheen/Scripts/My-scripts/GEN_POSCAR",

but you were told by MadeInGermany to do this:
Code:
# cd /scratch/scratchdirs/saleheen/Scripts/My-scripts
# ./GEN_POSCAR

As i sense there is some confusion about the directory concept, here it is:

Every file is placed somewhere under the "root"-hierarchy, which is denominated by "/". "/" is the topmost directory on every UNIX- (and UNIX-like) system. Now, every directory can hold two (in fact there are more, i am simplifying here) types of entries: other directories and files. Each of these other directories can also hold directories and files, and so forth. Every directory si separated by the directory "above" by a slash "/".

Therefore, "/scratch/scratchdirs/saleheen/Scripts/My-scripts" means: in the root directory "/", there is a directory "scratch". Inside "/scratch" there is another directory "scratchdirs", hence: "/scratch/scratchdirs". Inside "/scratch/scratchdirs" there is the directory "salaheen" and inside this is "Scripts", asf.. Inside the bottom directory "/scratch/scratchdirs/saleheen/Scripts/My-scripts" is a file called "GEN_POSCAR", which holds your scripts source code.

Think of it like that: you open the topmost box. Inside you find several smaller boxes (subdirectories) and some loose sheets of paper (files). Opening one of the smaller boxes you find again smaller boxes (sub-subdirectories) and other loose sheets of paper. And so on, until a box contains only loose sheets and no other boxes.

I hope this helps.

dh_installdeb

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.

       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.  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.

	   A versioned Pre-Dependency on dpkg is needed to use dpkg-maintscript-helper(1). An appropriate Pre-Dependency is set in
	   ${misc:Pre-Depends} ; you should make sure to put that token into an appropriate place in your debian/control file.

       This program is a part of debhelper.
