I have not tried what you want, Someone else may be able to give a
complete answer.

However, when I have a similar question, a very good and handy reference
to locate the answers for most and to lead me in the right direction in
shell scripting is the book /UNIX shell programming/ by Lowell Jar
Arthur and Ted Burns.

If I am considering Perl instead of the shell I use the /Perl Cookbook/
and /Programming Perl/ among others to get the details as to how/why it
works that way.

With these and a little research I find most things I need for anything
I want to do.  Over time even the difficult task becomes easier as the
techniques are learned.

YMMV
