Question

If I run a bash script as

./myscript.sh zone=A build=release

Is there someway I can read the arguments based on the parameters instead of using $1, $2?

Answer 1

No. Unix shells are an ancient technology, hash maps were known at the time but not “en vogue.” They needed more than 1 byte to implement so the professionals didn’t want to use such a wasteful technology.

What else can you do? The usual solution is getopt(1).

An alternative is to write all options to a file and source that:

echo "$@" | tr ' ' '\n' > options
. ./options

echo "zone=${zone}"
