Try [ "$port" != "PORT_C" ] && { read -p"Do you want to continue script? " ANS; [ "${ANS^*}" != "Y" ] && exit; }

Continue the original script OR run a new script? However, look into your shell's man page for the case statement.

Please read the proposal carefully. It does exactly what you specified: if PORT_A or _B, it asks the user and, if answer is y or Y , it sources a script called "script". If PORT_C, it does not ask...

Hello Ganesh,

RudiC code is good, only thing please change PORT_C to port_C, it should work then I think.

Thanks,
R. Singh

Don't call/source another script, exit the original script.

Try [ "$port" != "PORT_C" ] && { read -p"Do you want to run script? " ANS; [ "${ANS^*}" == "Y" ] && . script; }

Try this

awk '/[^-]-[^-].*:/{s = $1; next } NF==5 && $1~/[0-9]+/{print $2,s,$NF}' infile

[akshay@localhost tmp]$ cat infile
[ U-UU-YRYT-NOD-6002 ] GETA-TILL-INF;

No I mean directly, without using heads and tails..

cmd_sys NOD_$y GETA-TILL-INF | awk 'NR==3{s=$1} NR==8{p=1} /--/{p=0} p{print s, $NF}'

You haven't given any rule on how to select a) the prefix b) the data/data lines. Making wild assumptions, this will give the desired result for EXACTLY the...

For a new one, you writing quite complex scripts :p
Anyway, just writing the basics, try (untested):
while read tIP pIP
ping6 -c1 $pIP | grep -e trans -e ms && \
echo "$pIP : Found"...

Good morning:

I'd start by changing the main loop, first and last line:
To:
while read tIP pIP

done</home/lotus/bin/cmd/$iptable_fil
So it now reads the the first value for 't'elnet-ip,...

As has been stated many times, your requirement for a CSV output file and your requirement for fixed width output fields are conflicting requirements. The fact that you have presented three...

Do you mean you want the output in fixed-width columns?

When you don't use CODE tags to show how your input is formatted, it confuses volunteers trying to help you. When you say you want CSV output and show us text that is not in the format of a CSV file...

How about trying sth yourself? Anyhow, tryawk 'BEGIN {print "NODE ID IP"} {gsub(/\(|\)|\[|\]|NOD_/,_); print $2, $3, $6}' file
NODE ID IP

Do you have GNU awk?

Try:
awk '/NOD/ {print $2 OFS $4 OFS $11}' FS=' |\\]|\\[|\\)|\\(' Output.TXT

Or this should work on any version:
awk '/NOD/ {print $2 OFS substr($3,2,length($3)-2) OFS...

If we don't answer immediately, wait! Nobody here is "on call".

You must alter your expect script to return a value, 0 on success, 1 on error, so that your shell script can tell if anything goes...

> ip.csv would suffice, I think. This would not delete the file but render it empty.

The $ is not a command ;)

Change it to:
echo "" > ip.csv

You can do something like this
NodeId=$1
if [ -z "$NodeId" ]; then
printf "%s" "Enter the node ID here: "
read NodeId
fi

and then use $NodeId instead of $1 everywhere

Knowing what shell and operating system you're using could make a big difference here. In addition to what Scrutinizer suggested, maybe something like this will help with your problem:
