• Replace newlines with commas:

  • sd: sd '\n' ','
  • sed: sed ':a;N;$!ba;s/\n/,/g'

sed

sed -i 's;/resources;~/resources;g' repo.py

you can use any delimiter char for a sed expression

• doesn’t have to be/
• if you know you’re going to have/
• you can pick something else to avoid needing to escape / a bunch of times

One liner to remove lines that match a pattern from a file

This example removes [localhost]:56789 from ~/.ssh/known_hosts

sed -i '' '/^\[localhost\]:56789/d' ~/.ssh/known_hosts

As an alias

alias rm-known-localhost="sed -i '' '/^\[localhost\]:56789/d' ~/.ssh/known_hosts"

A line in ~/.ssh/known_hosts looks like

[localhost]:56789 name key
