Trying to describe regular expressions for use with the archive server, I just realized that arch_retrieve passes the regular expression unquoted to egrep. This means that regular expressions may not contain whitespace or shell meta characters. Is this intentional, or just a flaw?
Looks like a flaw to me. The use of $regxp on line 255 of arch_retrieve should be in double quotes.
PS: Shell meta characters seem not to hurt ([], (), and | work fine). How comes? Does flist unset IFS?
Shell syntax characters like (), |, and ; are never special when enountered as the result of variable expansion: shell syntax parsing is required to take place before variable expansion.
If no matches are found to a file globbing, the pattern is left unexpanded.
