Hi, folks:

In most programming language, we can have a tenary operator like:

A = ( condition ) ? A1 : A2;

How can I do this nicely in bash. Currently I am using:

if [ condition ]; then
A=A1
else
A=A2
fi

which looks baggy, any better ways to handle this, many thanks..

lihao..

A=$(( condition ? A1 : A2 ))
Depending on what "condition" is, you might do
test condition; X=$?
A=$(( X ? A1 : A2 ))
