How to get a variables from two different txt files and need to run a command using that values?
Hi

Q1. I have a scenario to run cfsend command,this command will run based on node name,port num,userid and password
I was created one file called test.txt and inserted two values,then called those two values from test.txt file that pointed to node place and ran the script it worked fine

Now i wanna create two or three files for port num,userid and password values to run the cfsend command

here is the script that i have written
Code:
#! /bin/sh
file=/venu/test.txt
while read node;
do
cfsend n:"${node}" port:46464 uid:tibco  pwd:Tibco123 pn:CHCKDIR ud:5563 trtype:c rcmd:"pwd"  
echo "PS is Down On" $node >>test.log
done< $file

Q2. the node names should change every time and will written one conman line "Failed Communicating with partner"
how can monitor only that message and write into a log file that display
".......(expecting the node that written that message) contains Failed Communicating with partner"

can anyone help?
Appreciate you help!

thanks,
venu

Do they really need to be in 3 different files? How about one?

The command may return a status which allows you to detect whether it failed without grubbing its text output. || is a short-form notation, command1 || command2 means "if command1 fails, run command2".

Also, you don't need to reopen your logfile 10,000 times for 10,000 different nodes, you can redirect the output of the entire loop once to catch it all.

Code:
while read NODE PORT UID PWD
do
        cfsend n:"${NODE}" port:${PORT} uid:${UID}  pwd:${PWD} pn:CHCKDIR ud:5563 trtype:c rcmd:"pwd" || echo "PS is down on $NODE"
done < table > output.log 2>/dev/null

it was my first question
thanks for the reply.yes i can use one file and pass all the values from there


can you answer my second question...........
the cfsend command will return the output everytime is

Code:
LocalTransactionNumber is I517600050
MFT Platform Server: Transfer Mode Set To Recv Result of Command
Failed Communicating with partner
Make sure the host is available
and the remote IP address and port are correct
Error Code -1

it could be changed based on the node name
my requirement is when ever any node send output contains Failed Communicating with partner,then need to write into a file with the node name

i used
Code:
cfsend n:PSCFSNB5 port:46464 uid:tibco  pwd:Tibco123 pn:CHCKDIR ud:5563 trtype:c rcmd:"pwd" | grep -Fxq "Failed Communicating with partner"

but,no luck!
please let me know if you have any idea!

thanks,
venu

Did you try my suggestion?

It may return an error code whenever it fails, which you can detect with ordinary shell logic, command || echo error

yes i tried and got below message

Code:
LocalTransactionNumber is I517600073
MFT Platform Server: Transfer Mode Set To Recv Result of Command
Failed Communicating with partner
Make sure the host is available
and the remote IP address and port are correct
Error Code -1
PS is down on

but my requirement is when ever node written Failed Communicating with partner that means Platform server is down on that node and expecting to keep monitoring for that message,if found write into a log file with the name

i wanna put that message in a log file to monitor,expecting in a single line like
Code:
Plat form server is down on ${nodename}with Failed communicating with partner message

if you have any code
please share with me
its helpful


thanks,
venu

It nearly worked! It printed PS is down on ...making me suspect you printed $NODE when you meant $node, or vice versa.

You also didn't redirect the output of the loop into the log file, and might need to redirect the command to /dev/null.

If you absolutely need to make life that much harder on yourself though, you can process the output instead of using the return value as designed:

Code:
while read NODE PORT UID PWD
do
        cfsend n:"${NODE}" port:${PORT} uid:${UID}  pwd:${PWD} pn:CHCKDIR ud:5563 trtype:c rcmd:"pwd" | grep -iq "failed communicating with partner" && echo "PS is down on $NODE"
done < table > output.log 2>/dev/null

Hi Corona,

I agree with you,but my requirement is to monitor only
"Failed Communicating with partner",then write into log file with the node name that it is generating that message

the command that you suggested me
Code:
cfsend n:"${NODE}" port:${PORT} uid:${UID}  pwd:${PWD} pn:CHCKDIR ud:5563 trtype:c rcmd:"pwd" | grep -iq "failed communicating with partner" && echo "PS is down on $NODE"

is not taking only that line,printing all the lines
Code:
LocalTransactionNumber is I517600073
MFT Platform Server: Transfer Mode Set To Recv Result of Command
Failed Communicating with partner
Make sure the host is available
and the remote IP address and port are correct
Error Code -1

any other command that could print only "Failed Communicating with partner"

thanks,
venu
