Subject: evaluation of env variables in DASH
Date: Wed, 19 Oct 2011 23:24:50 +0200 [thread overview]
Message-ID: <87aa8woesd.fsf@minignu.minidns.net> (raw)
Hi.
The following DASH behaviour seems buggy to me
-----------------
$ export A='\n'
$ echo $A
$
-----------------
whereas using BASH would result in printing literally \n .
I.e. presumingly DASH does secondary interpolation of escaped
symols in values of environment variables.
Please CC me with replies, I am not in the list.
Thanks, regards,
Dima.
P.S.
Wrom the other hand
$ export B=1
$ export A='$B'
$ echo $A
PRINTS $B
$
