$ cat /etc/services | sed -e 's/\W//g'

s/ means substitute.

^ matches the beginning of the line only so I've no idea why this even works in
cygwin.

\W means all whitespace. (conversely, \w means match a word)

/g means global.

I'm not certain how portable this is, but it does work for me.

I highly recommend reading the regex section in programming perl on the perl dfa
matching engine.
