I have based my script on the following quesstion
Find and replace text within a file using commands



I have a lot of files named test_xxx_01.sql in which i need to replace a text testoriginal with testoriginal_xxx
so I wrote the following command



for i in {220,630,1000}; do sed -i 's/testoriginal/testoriginal_${i}/g' test_${i}_01.sql; done


the expected output is that in the file test_221_01.sql, i should now have 'testoriginal_221'.



but instead i have testoriginal_${i}



how can i fix this command?

    It's basically a matter of using the right quotes - but be careful of metacharacters. See How can I use variables in the LHS and RHS of a sed substitution?

    You need to use double quotes for the expression.
