Question

i have a variable $x having a sample values like isd21anms.com, isd31anms.com etc. Now i want to iterate through for loop to change the no 1 from 1 through 1,2,3 4. Please look below code

for i in 1 2 3 4
do
     change $i such that I get values isd21anms.com, isd22anms.com, isd23anms.com, isd24anms.com
done

remember $x can have values like isd21anms.com, isd31anms.com, isd41anms.com. So i have to save it in variable and apply for loop on it instead of using a constant value.

Answer 1

for i in 1 2 3 4
do
y=`echo $temp | sed "s/\(.*\).\(anms.com\)/\1"${i}"\2/g"`
echo "y is $y"
done

tested below:

> ./temp.sh
y is isd21anms.com
y is isd22anms.com
y is isd23anms.com
y is isd24anms.com
> setenv temp "isd31anms.com"
> ./temp.sh
y is isd31anms.com
y is isd32anms.com
y is isd33anms.com
y is isd34anms.com
