unique entries needed
Hi All,

I have the following command which returns the output like this -

PHP Code:
wget URL|grep hostname|awk '{print $1,$3}'|/usr/bin/perl -nle 'm{"(.*?)".*?//(.*):(\d+)/} and print "$1 $2 $3"'|while read host port
do
echo check_env_$port
echo host
done 
OUTPUT
Appname hostname port
Appname2 hostname port2 ...

Appnames are all unique , while hostname is not since I am grepping for single hostname(vip).
Some of the ports are not unique so I am getting the same port for 4-5 different appnames.

Within the same snippet of code I want to add a number to echo command so the its unique..
e.g. check_env_1_1234
check_env_2_1234

So for port 1234 it should increment the numbers.

If that's too hard then atleast get unique entries so that I don't get check_env_1234 not more than once which ever comes first and ignore the rest of the entries with the same port.

Thanks,
Jack.

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
