# There are several domain name servers that allow # for bulk searching of domain names. # http://www.godaddy.com/bulk-domain-search.aspx # http://www.namestation.com/bulk-domain-search # However, they do not provide any wildcard support # and instead expect users to supply their own list. # Which is not a problem if you are an R coder. # This single command will copy to the clipboard a list # of mysite1 mysite2 mysite3....mysite500. You can then # paste it directly into the godaddy window. writeClipboard(paste0("mysite", 1:500)) # Using the built in vector letters will produce: # mysite-a mysite-b mysite-c....mysite-z writeClipboard(paste0("mysite-", letters)) # I have also written a bulk search command but # I am not sure that it is really any better than # the above command since it is really not as powerful. # However, it does demonstrate how one might # generate a wildcard search algorithm. bulk.search <- function(intext) { # Add spaces before and after intext <- paste0(" ", intext, " ") card <- c("|", "?", "#") # Declare the wildcards # Declare the wildcard values cardvalues <- list(c(letters,0:9), letters, 0:9) # A vector for saving wildcard detections ncards <- NULL for (i in 1:length(card)) ncards[i] <- nchar(gsub(sprintf("[^%s]", card[i]),"",intext)) stopifnot(sum(ncards)<2) # If a wildcard is selected expand the intext if (sum(ncards)==1) { intext <- unlist(strsplit(intext, card[ncards==1], fixed = TRUE)) intext <- paste0(intext[1], cardvalues[[(1:3)[ncards==1]]],intext[2]) } intext <- gsub(" ", "", intext) # Remove the extra spaces writeClipboard(intext) cat(paste("Coppied to clipboard:\n", paste(intext, "\n", collapse=" "))) intext } bulk.search("mysite?") bulk.search("mysite|") bulk.search("mysite#")Created by Pretty R at inside-R.org
