Subject: Double Evaluation Question (not in FAQ)
Date: Mon, 4 Sep 2006 08:18:19 +0200 [thread overview]
Message-ID: <F7507090F1A72B43A51444325DFBE431011F293C@MCHP7R6A.ww002.siemens.net> (raw)
Assuming that variables are assigned in the following way:
x=abc
y=def
z='$x $y' # Note: Single Quotes!
How could I write an expression, which "evaluates" $z, in
that it would return "abc def"? The simple
eval "echo $z"
would not work here, because it would not
preserve the spaces.
eval "echo \"$z\""
would indeed do the job, but I consider this a very ugly
solution because of the nested quoting. Does anyone know
a more elegant alternative?
