Top Forums Shell Programming and Scripting How to read and Split a file? Post 302885533 by clx on Monday 27th of January 2014 08:52:15 AM

Start with (always) looking at the man pages.

Code:
man head
man tail
man split

By your luck, all the three man pages are very small (single page), and you can understand them very easily.
Please ask back if you have any confusion about understanding.

dh_installmanpages

DH_INSTALLMANPAGES(1)						     Debhelper						     DH_INSTALLMANPAGES(1)

NAME

       dh_installmanpages - old-style man page installer (deprecated)

SYNOPSIS

       dh_installmanpages [debhelperoptions] [file...]

DESCRIPTION

       dh_installmanpages is a debhelper program that is responsible for automatically installing man pages into usr/share/man/ in package build
       directories.

       This is a DWIM-style program, with an interface unlike the rest of debhelper. It is deprecated, and you are encouraged to use
       dh_installman(1) instead.

       dh_installmanpages scans the current directory and all subdirectories for filenames that look like man pages. (Note that only real files
       are looked at; symlinks are ignored.) It uses file(1) to verify that the files are in the correct format. Then, based on the files'
       extensions, it installs them into the correct man directory.

       All filenames specified as parameters will be skipped by dh_installmanpages.  This is useful if by default it installs some man pages that
       you do not want to be installed.

       After the man page installation step, dh_installmanpages will check to see if any of the man pages are .so links. If so, it changes them to
       symlinks.

OPTIONS

       file ...
	   Do not install these files as man pages, even if they look like valid man pages.

BUGS

       dh_installmanpages will install the man pages it finds into all packages you tell it to act on, since it can't tell what package the man
       pages belong in. This is almost never what you really want (use -p to work around this, or use the much better dh_installman(1) program
       instead).

       Files ending in .man will be ignored.

       Files specified as parameters that contain spaces in their filenames will not be processed properly.
