Usage of ECHO and grep commands
set -A TELNET_HOST_ARR ${telnet_host_str}
The content present in telnet_host_str :-==========================================
alden 15.146.230.119 harpo 15.146.230.90 15.146.230.205
and target_system=alden
1>I found ipaddress by below way..Please let me know if you have any better idea.
ipaddress=$(nslookup ${target_system} |grep -p ${target_system} | grep Address | awk '{print $2}')
2>My doubt is in telnet_host_str eventhough i give ipaddress or target_system content "$? " status should be equal to zero.
echo ${telnet_host_str} || (grep $target_system && grep $ipaddress)
if [[ $? -eq 0 ]]; then
I did as above.Please let me know if you have better idea.
Thanks,
Shammer

Re: Usage of ECHO and grep commands
Why don you use netstat -in or nslookup.

Re: Usage of ECHO and grep commands
value is set by the last command in the
pipeline. In this case, that's your "awk"
command, not the "grep".
You could check for a null string ("-n" or
"-z"), instead of checking the final status.
(There are ways of extracting the status from
a command in the middle of a pipeline, but
they tend to be messy, or to use features
which are available only in fancy new shells,
like "bash".)

ipaddress=$(nslookup ${target_system} |grep -p ${target_system} | grep Addre
ss | awk '{print $2}')
echo $ipaddress<======== here getting correct answer
echo ${telnet_host_str} || (grep $target_system && grep $ipaddress)
if [[ $? -eq 0 ]]; then
lat_server=""
if [[ ${lat_server} = "rcon" ]]
then
...........
..........
else
lat_port=""
lat_server=""
echo $ipaddress<========= here getting value=0
please let me know...

Re: Usage of ECHO and grep commands
I've read your original post a couple of time now and am struggling to see what you're actually trying to do...
Could you clarify please.
Cheers
Rob

Re: Usage of ECHO and grep commands
My main intention is:-
set -A TELNET_HOST_ARR ${telnet_host_str}
where {telnet_host_str} contains ipaddress as well as hostnames of machines.
Current script is checking only if you mention hostnames of machines in telnet_host_str.
Current script:-echo ${telnet_host_str} | (grep $target_system)
if [[ $? -eq 0 ]]; then
So now i am enhancing the script to check for ipaddress as well as hostnames.
So i found ipaddress as below:-
ipaddress=$(nslookup ${target_system} |grep -p ${target_system} | grep Address | awk '{print $2}')
Checking the content of telnet_host_str :-
echo ${telnet_host_str} || (grep $target_system && grep $ipaddress)
if [[ $? -eq 0 ]]; then
Hope you understood.. Please let me know if you need further information..
Please let me know if you have better way of doing it..
Thanks,
Shammer

Re: Usage of ECHO and grep commands
Personally I'd look to use Perl rather than shell scripting as you are at the moment...
It should make things much more efficient.

Rob

Thanks,

Re: Usage of ECHO and grep commands
target_system=groucho
ipaddress="15.146.230.119"
set -A TELNET_HOST_ARR ${telnet_host_str}
Below are the list of contents present in $(telnet_host_str}:-
alden baknblak beggar biddy billion bingo bobcat bogey bradford bulldogs cos curly cyberstorm diamond dimaggi

If you want to check for BOTH being in the string you can use:
echo ${telnet_host_str} | grep $target_system | grep $ipaddress
