This is not a traditional shell script; it is not even a POSIX shell script. It includes non-standard syntax, and doesn't take advantage of the features of the POSIX shell.

## It works, it can handle different cases,
## The only drawback is it has several lines of code.

## Run it as: cat <input_file> | <this_shell>
Do not run it like that! There is no need for cat:

Code:
path_to_script < INPUTFILE

savefld1=""
Out=""
while read iLine
do
fld1=`echo $iLine | cut -f1 -d"-"`
fld2=`echo $iLine | cut -f2 -d"-"`
In a POSIX shell, you do not need cut to split up a string:

Code:
fld1=${iLine%%-*}
fld2=${iLine#*-}

Quote:
if [[ $fld1 = $savefld1 ]]; then
That is non-standard syntax; use the standard [ ... ] instead:

Code:
if [ "$fld1" = "$savefld1" ]; then[/QUOTE]

netid

netid(4)							   File Formats 							  netid(4)

NAME

       netid - netname database

SYNOPSIS

       /etc/netid

DESCRIPTION

       The  netid file is a local source of information on mappings between netnames (see secure_rpc(3NSL)) and user ids or hostnames in the local
       domain. The netid file can be used in conjunction with, or instead of, the  network source: NIS or  NIS+. The  publickey entry in the  nss-
       witch.conf (see	nsswitch.conf(4)) file determines which of these sources will be queried by the system to translate netnames to local user
       ids or hostnames.

       Each entry in the netid file is a single line of the form:

	      netname uid:gid, gid, gid...

       or

	      netname	    0:hostname

       The first entry associates a local user id with a netname. The second entry associates a hostname with a netname.

       The  netid file field descriptions are as follows:

       netname	       The operating system independent network name for the user or host. netname has one of two formats.   The  format  used	to
		       specify a host is of the form:

		       unix.hostname@domain

		       where  hostname is the name of the host and  domain is the network domain name.

		       The format used to specify a user id is of the form:

		       unix.uid@domain

		       where uid is the numerical id of the user and domain is the network domain name.

       uid	       The numerical id of the user (see   passwd(4)). When specifying a host name, uid is always zero.

       group	       The numerical id of the group the user belongs to (see  group(4)). Several groups, separated by commas, may be listed for a
		       single uid.

       hostname        The local hostname (see	hosts(4)).

       Blank lines are ignored.  Any part of a line to the right of a `#' symbol is treated as a comment.

EXAMPLES

       Example 1: A sample netid file.

       Here is a sample netid file:

       unix.789@West.Sun.COM	789:30,65
       unix.123@Bldg_xy.Sun.COM 123:20,1521
       unix.candlestick@campus1.bayarea.EDU    0:candlestick

FILES

       /etc/group	       groups file

       /etc/hosts	       hosts database

       /etc/netid	       netname database

       /etc/passwd	       password file

       /etc/publickey	       public key database
