You can extract the keys and values using a POSIX shell (sh) but you cannot store them in an associative array since sh does not have that feature. The best you can do is a generic list, which is just a text.

You're not getting the most out of UNIX if you can't write shell programs! This sections covers the POSIX shell, an improvement over the original shell. The actual shell executable might have.
Starting Bash with the --posix command-line option or executing set -o posix while Bash is running will cause Bash to conform more closely to the POSIX standard by changing the behavior to match that.
This book teaches portable shell scripting using POSIX-compliant syntax, ensuring your scripts work across Linux, macOS, BSD, and other Unix-like systems. Written with humor and practical.
refer to the same shell as that in POSIX.12008 so that interactive users can also be application programmers without having to deal with programmatic differences in their two environments. It is also.
Key Insights
Is it possible, or is there some elegant hack to do indirect variable expansion in POSIX as can be done in Bash? For context, I'm trying to do the following: for key in $ {!map_*} do # do some...
POSIX .
We require a script that simulates associative arrays or map-like data structure for shell scripting. Can anyone let's know how it is done?
