I added the echo in the loop to show that when nothing matches the N??? pattern the fn variable assumes value of N??? and that is the root of the question - when using
construct I thought the pattern evaluation happens before do and shell would simply not enter the do loop part when nothing matches.
Hi I have a bit of c code which I'm trying to use as a relay between apache and a scgi cluster.

wildmat
WILDMAT(3) Library Functions Manual WILDMAT(3)NAME
wildmat - perform shell-style wildcard matching
SYNOPSIS
int
wildmat(text, pattern)
char *text;
char *pattern;
DESCRIPTION
Wildmat is part of libinn (3). Wildmat compares the text against the pattern and returns non-zero if the pattern matches the text. The
pattern is interpreted according to rules similar to shell filename wildcards, and not as a full regular expression such as those handled
by the grep(1) family of programs or the regex(3) or regexp(3) set of routines.
The pattern is interpreted as follows:
x Turns off the special meaning of x and matches it directly; this is used mostly before a question mark or asterisk, and is not spe-
cial inside square brackets.
? Matches any single character.
* Matches any sequence of zero or more characters.
[x...y]
Matches any single character specified by the set x...y. A minus sign may be used to indicate a range of characters. That is,
[0-5abc] is a shorthand for [012345abc]. More than one range may appear inside a character set; [0-9a-zA-Z._] matches almost all of
the legal characters for a host name. The close bracket, ], may be used if it is the first character in the set. The minus sign,
-, may be used if it is either the first or last character in the set.
[^x...y]
This matches any character not in the set x...y, which is interpreted as described above. For example, [^]-] matches any character
other than a close bracket or minus sign.
