Problem using sed in script
Hey guys,

I'm looking to write a script that takes a variable line number and prints that line via sed, but I'm having an issue with the syntax. As I understand it, the sed syntax to print line number 52 (for example) is as follows:

sed -n '52p'
sed '52!d'
sed '52q;d'

But how can you make 52 a variable when everything is surrounded by single quotes? I've tried double quotes and omitting the single quotes to no avail. Does anybody know?

Thanks!

Code:
a=52
sed "${a}q;d" myFile
