Hi,

I want to write a script which will compare the 1st column of both the files and will give the difference.
e.g:-
my 1st file contains:

89 /usr
52 /usr/local
36 /tmp
92 /opt
96 /home
27 /etc/opt/EMCom
1 /SF_Appl_01
7 /SF_Data_01
1 /tmpiq


my 2nd file contains:
79 /usr
22 /usr/local
26 /tmp
92 /opt
86 /home
17 /etc/opt/EMCom
1 /SF_Appl_01
7 /SF_Data_01
8 /tmpiq
87 /HS_Appl_01
86 /HS_Data_01


Now I want to find the differnce of 1st column of both the files and notify if differnce is more than 10. Please help me on this.

LEARN ABOUT FREEBSD

man.conf

MAN.CONF(5)						      BSD File Formats Manual						       MAN.CONF(5)

NAME

     man.conf -- man(1) and manpath(1) configuration files

DESCRIPTION

     The man.conf file is used to configure the manual search path, locales, and utility set for man(1) and its related utilities.  During ini-
     tialization, man(1) reads the configuration files located at /usr/local/etc/man.d/*.conf and /etc/man.conf.

     The files contained in /usr/local/etc/man.d/*.conf are intended to be used by the ports(7) system for extending the manual set to support
     additional paths and locales.  /etc/man.conf is intended to be used by the local administrator to set additional policy.

     Currently supported configuration variables include:

	   MANCONFIG	 Overrides the default location to import additional manual configuration files.  Defaults to /usr/local/etc/man.d/*.conf.

	   MANPATH	 Adds the specified directory to the manual search path.

	   MANLOCALE	 Indicates support is available for the given locale.

     For pages in a given language, overriding the default toolset for display is supported via the following definitions:

	   EQN_LANG
	   NROFF_LANG
	   PIC_LANG
	   TBL_LANG
	   TROFF_LANG
	   REFER_LANG
	   VGRIND_LANG

     See the EXAMPLES section for how to use these variables.

IMPLEMENTATION NOTES

     The parser used for this utility is very basic and only supports comment characters (#) at the beginning of a line.

FILES

     /etc/man.conf		     System configuration file.
     /usr/local/etc/man.d/*.conf     Local configuration files.

EXAMPLES

     A perl port that needs to install additional manual pages outside of the default location could install a file in
     /usr/local/etc/man.d/perl.conf with the following contents:

	   # Add perl man pages to search path
	   MANPATH /usr/local/lib/perl5/5.8.9/man
	   MANPATH /usr/local/lib/perl5/5.8.9/perl/man

     A Japanese localization port could install a custom toolset and include a file in /usr/local/etc/man.d/ja-man-doc.conf with the following
     contents:

	   # Setup Japanese toolset
	   MANLOCALE	   ja_JP.eucJP
	   EQN_JA	   /usr/local/bin/geqn
	   PIC_JA	   /usr/local/bin/gpic
	   TBL_JA	   /usr/local/bin/gtbl
	   NROFF_JA	   /usr/local/bin/groff -man -dlang=ja_JP.eucJP
	   TROFF_JA	   /usr/local/bin/groff -man -dlang=ja_JP.euc.jp

     If the system administrator decides to override the LOCALBASE make(1) variable causing all ports(7) to be installed into /opt instead of
     /usr/local, specifying the following in /etc/man.conf will accommodate this change:

	   # Look for additional configuration files
	   MANCONFIG /opt/etc/man.d/*.conf
