I am writing a script to search files in a certain pattern
and manipulate them. Something like:
for i in *.vhd; do
# do some operation on $i here
done
# do other stuff
This works fine if there is at least one file matches the
pattern. Otherwise, it exits with an error and 'other stuff'
never gets done.
How can I make it so that it will just skip 'for' loop if
there aren't any files matches the pattern?

for i in *.vhd(N); do
# do some stuff
done
The (N) says to use the nullglob option for this particular
glob pattern.

Writing
for i in *.vhd(N); do
is better since it does not change the options (the setopt nullglob
is "local").
