How to count the length of fasta sequences?

I could calculate the length of entire fasta sequences by following command,
Code:
awk '/^>/{if (l!="") print l; print; l=0; next}{l+=length($0)}END{print l}' unique.fasta

But, I need to calculate the length of a particular fasta sequence specified/listed in another txt file. The results to to be printed in a csv file.
Therefore, please help me to do the same.
Thanks in advance.
