Hi,
I want to substitue some variable names, to build another variable,
therefore I have a script like this:
#!/bin/bash
NETS="NET0 NET1 NET2"
NET0_IF=eth0
NET1_IF=eth1
NET2_IF=eth2
CNT=0
for NET in $NETS;do
echo ${${NET}_IF}
done
What I want is the output to look like like:
eth0
eth1
eth2
but whatever I try, it ends with a "bad substitution", or wrong output.
Is there a way of this kind of double substitution in bash?
kind regards
Sebastian
