Comment:
I guess you're missing a negation there (you're failing if the package is
found).
Don't use `grep -q`, it's not portable. Instead use `grep >/dev/null`.
Finally, your regular expression is probably too complicated, I think
{{{
grep '^fricas-.*' >/dev/null
}}}
should suffice. Your counterexample `fricasaldor-1.0.9` doesn't match it!
To be very safe, use `ls -1` instead of a plain `ls`.
