Pipe to/from the clipboard in Bash script

At home, I can send a link from any device to a local web server that saves it for later. Then, when I have time to read, I can see all my saved articles, move them into folders, and refer back to them as needed. At work, though, those links go into a text file. When I get home, I find the text file, open it, copy the list, clear the file, close it, and then send the list to the server. pbcopy makes that process just a little easier. Now, cat ingest.txt > pbcophy & echo "" > ingest.txt puts the contents of ingest.txt on my clipboard and then clears the file, so I can add the links through the web interface with just a bit less hassle.
