Neither of my questions has been answered, none of my suggestions was applied, helpful info was not supplied. Instead of focusing on one problem (specified in the first post), you are broadening the operating field and introduce new errors. In your last post, there are at least two syntactical errors: spaces around the equals signs when assigning shell variables, and single quotes around the variables preventing them from being expanded. No surprise it doesn't do what you expect.
Unless you supply info enabling people to help you, I'm afraid I can't help further.

INFO(5) File Formats Manual INFO(5)
NAME
info - readable online documentation
DESCRIPTION
The Info file format is an easily-parsable representation for online documents. It can be read by emacs(1) and info(1) among other pro-
grams.
Info files are usually created from texinfo(5) sources by makeinfo(1), but can be created from scratch if so desired.
For a full description of the Texinfo language and associated tools, please see the Texinfo manual (written in Texinfo itself). Most
likely, running this command from your shell:
info texinfo
or this key sequence from inside Emacs:
M-x info RET m texinfo RET
will get you there.
AVAILABILITY

Please send bug reports to bug-texinfo@gnu.org, general questions and discussion to help-texinfo@gnu.org.
