set -x
var_123=123
f() {
while (( $# )); do
shift
local var=var_123
local -n var=$var; : status is $?
local -p
: var is $var
done
}
f one two
Running above script gives the follow output:
+ var_123=123
+ f one two
+ (( 2 ))
+ shift
+ local var=var_123
+ local -n var=var_123
+ : status is 0
+ local -p
var=var_123
+ : var is 123
+ (( 1 ))
+ shift
+ local var=var_123
+ local -n var=123
./x.sh: line 10: local: `123': invalid variable name for name reference
+ : status is 1
+ local -p
var=var_123
+ : var is 123
+ (( 0 ))
With Bash 4.3 the output is:
+ var_123=123
+ f one two
+ (( 2 ))
+ shift
+ local var=var_123
+ local -n var=var_123
+ : status is 0
+ local -p
var=var_123
+ : var is 123
+ (( 1 ))
+ shift
+ local var=var_123
+ local -n var=var_123
+ : status is 0
+ local -p
var=var_123
+ : var is 123
+ (( 0 ))
Thanks
