The original sed command from the first email:
sed -n -e '/^default/ s/^default.*dev //; s/ .*// p;q'
It's equivalent to this:
head -1 | sed 's/^default.*dev //' | sed 's/ .*//'
In plain English:
1. Take the first line.
2. If a portion of the line matches '^default.*dev', remove it:
3. If a portion of the line matches ' .*', remove it.
