The following bash script prints out c
, but I'm not sure why.
a=b
b=c
echo ${!a}
I believe that !a
will be converted to the last command which began with a
, so in this case that would be a=b
. This should mean that the last command is equivalent to the following.
echo ${a=b}
However, that prints b
, not c
. Is anyone able to explain why this is the case?
