Question

in my bash script I use a regexp to match a string of variable assignment,
for instance:

1. Var = Value
2. var = Value;
3. Var=Value
4. Var=Value;
5. Var Value

the regexp i developed: \s*${varName}\s*\={0,1}\s*.*\s*;{0,1}

this regexp can match every instances above but also another instance that I don’t want, which is VarValue

I cannot think of a way to make my regexp to not match the VarValue instance.

Modifying yours:

\s*${varName}(\s?[\s\=]\s?).+\s*;{0,1}
