Hi,
I'm trying to understand expansion end substitution and I'm lost in
what should be a simple substitution. Here my example


foo=4
echo ${foo}

4

FO=fo
O=o
echo \${${FO}${O}}

${foo}

while I was expecting '4'. What am I missing?


eval echo \${${FO}${O}}

But I guess this is not what you expected.
