[SOLVED] sed -n command or variable substitution

Issue

I'm trying to substitute date command in sed.

As shown below, I'm trying boh command & variable substitution but neither of the approaches produce output. I've tried a few things of which I'm posting below the one that doesn't error out.

sed -n "/$(date -d '1 year ago' '+%Y-%m')/,$p" filename.csv

search=$(date -d "1 year ago" '+%Y-%m')
sed -ne '/"${search}"/,$p' filename.csv

How could I substitute either a variable or a command into sed please?

Solution

sed -n '/'"$(date -d "1 year ago" '+%Y-%m')"'/,$p' filename.csv
