if somthing is equal to nothing ?

[TRiNuX]

Hey..

using if,then,else....
how can I check if a variable is equal to nothing?

{if $var == ""} gives an error saying 'extra characters after close-bracket'

I'm probably using the wrong syntax.. anyone help?

you typed it wrong, try

Code: Select all

if {$var == ""} { 
  #do stuff 
}
