Using a variable in an expression 1

[cuttersw]

Nooby question:

I am trying to use a variable in a 'match' expression but am having no luck. Can anyone advise how i should be doing this.

This works:
$4 ~ /@domain.com/ { print NR "\t" # $0 }

But this does not:
variable="@domain.com"
$4 ~ /$variable/ { print NR "\t" # $0 }

Shaun.

variable="@domain.com"
$4 ~ variable { ... }

Hope This Helps, PH.

Could have swore i'd already tried that but obviously not as it works fine! - Thanks very much for the help PH.
