cat | sed -e 's,%,$,g' | sudo tee /etc/init.d/dropbox << EOF
echo "Hello World"
EOF
What does the “sed” command do?

sedis the Stream EDitor. It can do a whole pile of really cool things, but the most common is text replacement.The
s,%,$,gpart of the command line is thesedcommand to execute. Thesstands for substitute, the,characters are delimiters (other characters can be used;/,:and@are popular). The%is the pattern to match (here a literal percent sign) and the$is the second pattern to match (here a literal dollar sign). Thegat the end means toglobally replace on each line (otherwise it would only update the first match).
