Using Sed to Delete Words in a File
This is a Nagios situation.

So i have a list of servers in one file called Servers.txt

And in another file called hostgroups.cfg, i want to remove each and every one of the servers in the Servers.txt file.

The problem is, the script I wrote is having a problem removing the exact servers in the Servers.txt file.

Code:
for EACH in `cat /var/home/me/Servers.txt`

do

cat /var/home/me/hostgroups.cfg | sed "s/$EACH//g" > /var/home/me/hostgroups.cfg1

cp /var/home/me/hostgroups.cfg1 /var/home/me/hostgroups.cfg2
cp /var/home/me/hostgroups.cfg1 /var/home/me/hostgroups.cfg

done

The hostgroups.cfg file often contains servernames with similar matching names and getting sed to remove JUST the server in the $EACH variable is another problem i keep encountering.

can someone please help me with this?

slist

SLIST(1)							       slist								  SLIST(1)

NAME

       slist - Lists available NetWare Servers

SYNOPSIS

       slist [ pattern ]

DESCRIPTION

       slist lists all NetWare Servers available in your network.

       If slist does not print to a tty, the decorative header line is not printed, so that you can count the servers on your network by doing

       slist | wc -l

OPTIONS

       pattern
	  pattern is used to list only servers whose names match the specified pattern. For a server to be listed, the pattern must match the full
	  server name. You can use wildcards for the pattern, but you must protect these wildcards from any command  line  expansion  by  quoting.
	  Case doesn't matter.

EXAMPLE

       slist "I*"

       or

       slist "i*"
	      List all available Netware servers on your Network, that begin with an "I".

SEE ALSO

       ncpmount(8), ncpumount(8), pqlist(1), nprint(1)

CREDITS

       slist was written by Volker Lendecke (lendecke@math.uni-goettingen.de)

BUGS

       slist works only in IPX environment, as it uses SAP to find first server and then Bindery to get list of servers.
