Instant configuration restoringThe configuration we have seen in this chapter might take some time to set up manually, but, onceeverything is configured, we can create a script that will restore the Vim configuration instantly.For this, we paste all the commands issued up to now into a bash script that can be run to bring Vim tothe exact same configuration. All that is missing from this script is the vimrc file from the homefolder, which we can also restore through a technique called heredocs. Just type cat, redirect theoutput to vimrc, and use heredoc as input, delimited by eof:cat > ~/.vimrc << EOF...<vimrc content>...EOF
Using heredocs is a common technique for manipulating large chunks of text inside bash scripts.Basically it treats a section of code like a separate file (in our case everything after the cat and untilthe EOF). With this script, we can restore all the Vim configurations we have done and we can alsorun it on any computer we work on, so that we get our Vim set up in no time!We hope you have enjoyed this material and see you in the chapter!
