Subject: Variable Replacement Question
Hello all,
COMPANY='JOE'S TRUCKING CO. ' <== Problem (3 hyphens in one line)
^=== when using hyphen as part of variable
COMPANYx='JOES TRUCKING CO. ' <== Not a problem, theres no hyphen in
JOES
ADDRESS='123 MAIN ST. '
Couple of requirements:
1. The hyphens enclosing the entire variable MUST be used as displayed
above.
Open/Closed quotation marks cannot be used... single or double.
2. Objective is to change JOE'S ==> JOES as in COMPANYx above
WITHOUT modifying the the first and last hyphens.
I'm hoping there's a simple solution... but my noodle is cooked.
Any input would be greatly appreciated.

I think you need to re-post that.
I don't even see one hyphen and don't know what the problem would be if
there were.
... ah, you mean single forward quotes?
easy, but somethings are still not clear, but I'll assume that this is a
file or data stream that you have to process that has lines that look like
that
and not a script you can edit directly where the problem is merely how to
handle variables containing tricky data.
In other words, these are not variables (at least not at this point), they
are lines of text. (which will probably be variables in some later step.)
One way might be to strip all quotes, then add the leading & trailing back
on.
awk -F= -v q=\' '{gsub(q,"",$2);print $1"="q$2q}' in.txt >out.txt
or
myprog |awk -F= -v q=\' '{gsub(q,"",$2);print $1"="q$2q}' >out.txt
If you meant something else and you are inside a script and there are
variables whose contents contain the quotes, then this will do it, uglily:
COMPANY=\'`echo "$COMPANY" |tr -d "'"`\'
you only need the 2nd variable COMPANYx if you want to preserve the
original, and both of these do preserve the trailing spaces.
I'd cut & paste that 2nd one if you need it. It has both forward and back
single quotes in it and some fonts do not show the difference very well
just by eyesight.
