Bash variables: case sensitive or not?

StackOverflow https://stackoverflow.com/questions/15571706

Question

Is bash shell scripting case sensitive?

Is variable date the same as DATE?

Was it helpful?

Solution

Yes, it is case sensitive, just like the rest of UNIX. $date and $DATE are two different variables. makefile and Makefile are two different files. -h and -H are two distinct flags (usually).
