Using Sed to Append Lines to File During Vagrant Provisioning

Question

I\'m currently using Vagrant to set up a development machine running Ubuntu. I want to add a few lines to my .profile that add directories to my $PATH

Answer 1

To fix "sed: -e expression #1, char 44: extra characters after command", escape \n, that is add another backslash to all \n:

config.vm.provision "shell", inline:
"sudo sed -i \'$ a if [ -d \\\"/usr/local/lib\\\" ] then\\n    PATH=\\\"/usr/local/lib:$PATH\\\"\\nfi\' /home/vagrant/.profile"
