Hi,

There are several errors in your script. Try something like this:
Code:
$ cat script.sh
#!/usr/bin/env bash

while read line
do
        WInstname=`echo $line | awk -F"Iname -" '{print $2}'`
done < input.txt
echo "$WInstname"
$ bash script.sh
 123

Regards,
Birei

Thnks bro..We did exactly like you said however we are getting a blank output

[user@machine]# cat test
#!/usr/bin/ bash
while read line
do
WInstname=`echo $line | awk -F "Iname -" '{print $2}'`
done < input.txt
echo $WInstname





#WInstname = awk -F"Instancename -" '{print $2}'
[user@machine]# cat input.txt
Iname - 123

[user@machine]# ./test

[user@machine]#

Looks like there is a space in your shebang statement between bin/ and bash. i.e. first line
#!/usr/bin/ bash

Remove the space and try.

Code:
awk -F"-" '{print $2}' iput.txt
