Last active Aug 7, 2020
How can I replace a newline (\n) using sed?
View How can I replace a newline (\n) using sed.md

stackoverflow (hdorio)

Fast answer:

sed ':a;N;$!ba;s/\n/ /g' file
  1. :a create a label 'a'
  2. N append the next line to the pattern space
  3. $! if not the last line, ba branch (go to) label 'a'
  4. s substitute, /\n/ regex for new line, / / by a space, /g global match (as many times as it can)

Adding Ubuntu PPA repository behind a firewall. When you are behind a corporate firewall that only allows outbound traffic on ports 80 and 433 the usual apt-add-repository command will not work. To get around it. Here is the workaround.
View gist:4531580
# trying to install PPA behind firewall fails:
$ sudo add-apt-repository ppa:chris-lea/node.js
gpg: requesting key C7917B12 from hkp server keyserver.ubuntu.com
gpgkeys: HTTP fetch error 7: couldn't connect to host
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
recv failed
# this is how you get around it (use the key from the command above)
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys C7917B12
