Question

I’m trying to replace a line of text in a properties file.
For example:

food.type=banana

With this line of code I can replace banana entirely with another entered input.

FOOD=apple
sed "s/food.type=.*/food.type=$FOOD/" 

Output:

food.type=apple

However when the previous line of text I’m trying to replace has a / in it, I can’t get the replacement to work.
For example:

food.type=/yellow/banana

Any help is much appreciated. Thanks!

Answer 1

The slashes are being read as closing the reg-ex match/substitute patterns,

Do

sed "[e-mail]=.*@food.type=$FOOD@" 

Some seds require that you escape the first instance of a non-standard delimiter, ie

sed "s\@food.type=.*@food.type=$FOOD@" 

I hope this helps.
