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? – steeldriver Apr 05 '19 at 12:06

You need to use double quotes for the expression. – pa4080 Apr 05 '19 at 12:12
