Hi there,

I wanted to pick a variable from a file dynamically, to be used
in following kind of loop

do
commands <variable to be taken from file>
done


file contains a list of variables to be used in the loop.

How can I use those in the loop dynamically?


Thanks in advance

If you want variables from one file to other use

source filename

This will read the file filename and get all the variables.

Easiest (non secure etc) way: store the file in form variable=value and in each iteration 'source' the file

Hello again,

I am sorry guys better I would have searched before I posted my
problem.

As it is:-

billym.primadtpdev>cat ~/1

while read line;do
eval $line
done
echo $XX_abba $XX_beatle $XX_cloop


My implementation simplified:-

alive.sh:--------------------------------


echo Pinging $lnx
ping -c 1 $lnx
if [ $? != 0 ]; then
echo
echo
echo
echo OOPS $lnx is not responding
echo
echo
echo
fi

for line in `cat ser.dat`
do lnx=$line
export lnx
