The `-x' operator WFM. Does, say, this script fail for you (make sure perl
is *actually* executable) ?
#!/usr/bin/perl
if (-x "/usr/bin/perl") {
print "yupp, perl is executable.\n";
} else {
print "ut-oh! perl isn't executable.\n";
}
If you haven't already posted cygcheck[1] output, that might help, and also
post your script (I couldn't find it in my archives). Sorry if you've
already done this.
