Can we pass a gitlab variable with multiple elements to a shell script

Question

I have a gitlab variable as below:

REGIONS: us-east-1 us-west-2 eu-central-1

I want to pass this gitlab variable to a shell script. But when I pass it to script, its fetching only first element and rest are ignored. The code used to pass variable is: test.sh $REGIONS

Is it not possible to pass it like that or is there a way for it. Please help.

Is us-east-1 us-west-2 eu-central-1 supposed to be three separate values in an collection or one long value? — Daly

@Daly: In script it will loop through each regions. If I directly hard code this in code, it works. — Nikhil Thomas

If REGIONS="us-east-1 us-west-2 eu-central-1", then calling

test.sh $REGIONS

means that

us-east-1 will be assigned to the first positional parameter $1
us-west-2 will be assigned to $2
eu-central-1 will be assigned to $3

All the variables can be get using $@, but a simpler solution would be quoting the variable:

test.sh "$REGIONS"

In this case $1 will contain us-east-1 us-west-2 eu-central-1
