Appending a variable

[sumncguy]

In Sunos Ksh ...
if iplist contains a list of ip address :

while read ips
do
$nlist=`echo $ips`
echo "$nlist"
done < iplist


every time through the loop, $nlist is rewritten.
I want to append a variable with every iteration through the loop instead of rewriting it. (although wrong) something like this ..

echo $nlist >> $finallist


Thanks alot

Something like this ?
while read ips
do
nlist="$nlist $ips"
echo $nlist
done < iplist

Hope This Helps, PH.

How about...

#!/bin/ksh

export FINALLIST=$(cat iplist | tr '\n' ' ')

print ${FINALLIST}

That puts each line in the file one one line in the variable, separated by spaces.

UUOC Police!

#!/bin/ksh

export FINALLIST=$(tr '\n' ' ' <iplist)

print ${FINALLIST}

#!/bin/ksh

export FINALLIST=$(cat iplist | cat | cat | cat | cat | tr '\n' ' ')

print ${FINALLIST}

Watch it Sam!!!

Or I'll have you repeat 100 times: "I will not use cat unnecessarily in shell scripts" [robocop]
