Even without the shopt -s extglob the folllowing is expanded: echo {*,*/*,*/*/*}.{opt,texi}

Yes 97 works, but not 10.
The problem is that the $( ) (likewise the ` `) strips a trailing newline; this is mostly for convenience.

x=$(echo "

When read indicates an EOF and the loop ends, it still has read the last incomplete line into the variable.
So you can process it after the loop.

I am not an AIX expert, but NFS is a standard - I guess IBM even licenced it from SUN.
The NFS version is "negotiated" once, at mount time. The client simply asks the server via rpcinfo what...

With an ERE you can ensure the input is a number:
[[ $NUM =~ ^[0-9]+$ ]] || continue

&2>/dev/null is still odd, the & is too many. The & before a descriptor number is needed on the RHS only, to distinguish it from a file name.

With two capture groups and back-references one can insert a newline in the middle:
sed 's/\(.\)\(.:\)/\1\

Consequently you should replace the other grep -E -q with a [[ =~ ]].

And &2>/dev/zero looks odd. Perhaps you mean 2>/dev/null but this is not appropriate after a [[ ]] compound.

If it arranged like this, two fields per line, then you can sort by field 2 numerically

Pipe this to a tool that displays the first (head-1) or the last line (tail-1).
