Look this:

mediaid=WNT001

echo '/$mediaid/d|x' | ex - scratchtapes

Runnig this command I get :

Pattern not found

My question:

echo '/$mediaid/d|x' | ex - scratchtapes
^
|
How can I put a variable in this command ?

Thanks
Obrigado

Single quotes will take the $ literally, while double quotes will expand
the enclosed variables. (You'll see that if you omit '| ex ...' part.)
